Welcome to Teardown! Tuesday We've got something interesting today. Check out this beast. It's an 82 watt LED Luminaire light while these industrial ones that you are you know hang from the ceiling in factories and things like that. Thank you very much to Frederic Wang from Lot Light and Star they're called.

Who sent this in? He's the CEO of Light and Star. This is a new product. there are designed and selling and it's a real chunky industrial beast. This is a hundred and fifty-nine Australian dollars delivered.

Yes, it's a is specifically designed for the Australian market, but it's also designed for the US and UK markets as well. so it comes permanent with the proper plug with the insulating pins or fully type approved. All that sort of jazz and it is in 8150 Lumen 82 What? LED spotlight for Eva wall or ceiling mounted but generally ceiling mounted for like factories and things like that where you know just light the things up. Designed for 14-7 operations, so pretty much 14 hours a day, seven days a week, very long life, all that sort of stuff.

So it's I think it's actually really quite nice. I Thought we'd do a teardown. I Mean there's not going to be much in it apart from the switch mode, constant current power supply, and the LED chip on board module which we'll take a look at but should still be interesting. Check out that lens in this puppy.

Look at that. Fantastic is that. Don't Don't know if that's a chip or a little imperfection. But anyway, very very nice.

This whole outer case here is all. this is like the heatsink for it. which is it doesn't look like that just for kicks. It needs to actually dissipate all the heat.

Thermal design with these things is you know the most critical aspect of this and that's the thing about this. It's designed for 40,000 hours continuous operation, a 10-year lifespan. It's got a five year warranty on the thing and it only gets am the lead in here which will I take a look at the data sheet for this only gets a 3% output loss after 5 years and it's designed to operate really cool. a maximum temperature rise of 20 degrees C which they claim is like 70% of your typical LED luminaires out there for like you know, factory illumination and things like that.

So yeah, 10 year lifespan, Real. feels like real beefy industrial quality. Really liked it and quite decently priced. 120 US dollars delivered or you can actually pay a bit more and get it I think 30 bucks more or something and get it shipped really fast like in a couple of days.

So the LED module used in this, which we'll take a look at has an efficacy of 99 lumens per watt. You can actually get that's not like the highest on the market, but you can actually get up to 135 lumens per watt from this chip on board module manufacturer which we'll take a look at. But yeah, at 82 watts, that's our 8000 150 lumens rated output 105 degrees C beam angle on the thing so it is actually quite a wider beam angle because you need that when you're lighting from you know the ceiling high up designed for Heights between 3.5 and 5 meters. so you know typical like industrial type Factory Heights and this will give at least 300 lumens over the entire illuminated surface minimum from that height.

So it really is quite a light. Now this model is actually called the In Dual LED module and they only make the one type at the moment with the one color temperature. This is our 5700 K color temperature with the one angle 100 and not 5 degrees but I'm assuming that you know if they've got interest, they'll make ones with different color temperatures and ones with different angles and things like that and glass lens in there. Look at that.

Hmm and it's designed to operate in environments from minus 20 to plus 55 degrees. C As I said, it's got a it's designed to have a temperature rise of at when he degrees see in continuous operation obviously with full you know like hanging in free air kind of thing. It's not like can stick this thing in like some ceiling void and you know expect it to get the same temperature. It comes with a little hook by the way like a screw in I hook so designed to either be wall mounted or hanging from like a guy wire from the ceiling.

There's the badge for those playing along at home. light and star it's the in dual model are 82 watts are normally in Port The CRI is actually quite low. it's only at 70. so as I mentioned in previous LED videos like you know indoors especially if you're doing video and stuff like that you want a d-plus but this one is specifically designed for like industrial environments where the CRI doesn't really matter and Frederick tells me there's just not much call for any CRI greater than 80.

So in terms of the Co B LED module manufacturers in not China they mostly like for the real high power ones they mostly turn out a CRI 70. so if you want a highest and color rendering index it's going to be you know it's gonna cost a lot more and be Availability isn't as good but they will be released in a commercial model soon which will use Art Citizen brand LEDs and that has a color rendering index of greater than 90. So yeah if you using these for like an indoor video studio or something like that then you'd hold out for something like that you you wouldn't use something with a CRI of 70 so I wouldn't necessarily use this one here in the lab here because I Need you know? color balance on my videos is quite important. so if you have a low CRI it just doesn't.

It's exactly what it says. Color render. It doesn't render accurate colors in the things that you're shooting well enough. so.

I wouldn't mix the unless I Was definitely desperate I Wouldn't mix these lights in here with my studio layers. but something for like my bunker. well that has high concrete ceilings. Absolutely perfect.

Hang it from there lights up the entire bunker. Brilliant! Thank you very much. Frederick We're gonna take a look at this puppy. haha.

You know we say you're on the eevblog. don't turn it on apart. So what we got here is a gigantic heat sink right around the lid. That's where all the thermal business is happening.

We'll take a look inside. Hopefully we'll see the thermal couple in between the Co B module and the and the massive heat sink. Here this is where our power supply is going to be. It uses a top quality Meanwell branded power supply module so it'll just be in here so the Warran inside it doesn't use any custom electronics.

I Don't believe I Think it's just you know it. mains input. They've got a decent quality penetrator here and it looks like it's all sealed right around the edges. I Can see like silicon sealant? actually.

Actually, you probably can't see it on that side. Maybe on the other you can see it sort of like something. They've got some sort of seal in there. This is, um, Ip66 rated so you know it'll handle like the you know, the occasional splash and condensation and that sort of jazz.

But yeah, it feels like it's really built like a brick Donnie. It really does. Very solid construction. really like it and we'll take a look at that.

see. OB module. Of course that feels like a solid glass lens. It's got a see.

It looks like a rubber seal around the glass lens in there. Curious to see what these screws do? I might pop those off and maybe this. South front cap pops off and might be able to get a look at the LED module without having to unbolt the rest of it. That'd be nice.

And here we go. Got the screws out. We should be able to just pop this. Pop this puppy out tonight.

Yeah, I can just lift the lens off. Time to get my grubby mitts on on that Tada. Oh no. our LED Oh no.

I thought our LED module had slipped. but it wasn't It was just that little aluminium bracket there. Tada. there it is.

Well, we don't have to get any further. we don't have to. Why extract this thing from the back? We're in like Flynn There's our Co B or chip on board LED module. Nice, that's got a thermal paste using out there from the sides as you can see and screw you.

I mean we could take that Oh like I could unscrew that but there's no point really because you know we're not going to see anything. It's going to be an aluminium backing plate on there which then just goes directly down to the UH Nana tae Yun anodized of course heat sink at the bottom. the rest of its energized of course for your increased heat dissipation. This Co B module is manufactured by a Chinese company called Hong Li Tronic and Frederic assures me that they're one of the bigger manufacturers of these are Co B modules in China so you know they're fairly reputable in that respect and I'll show you we'll go through the data sheet in a minute, but it's basically an array of individual lead elements like this um, these Co B or chip onboard modules just like you know, the chip on board that you get on a regular PCB For example, they'll put the bare die on the board and then they bond Y the things across and then blob the whole thing.

basically doing a similar thing here instead of your traditional approach of using the PCB and then getting the individually packaged LED modules solder in them onto the PCB having your you know your thermal vias and everything else. Take the power out the back and you have all you have you amount or you surface mount reflow them on and aluminium back. PCB For example, getting the manufactured in one big CIB module like this is much more efficient. You don't have to assemble the things yourself, The thermal properties are a lot better.

There's lots of advantages to this. That's why a lot of companies are now producing these Co B modules. They're just regular LED dyes that you get in your individual lead package. You know that? Real high efficiency LEDs Individual LEDs You'd buy, but they actually take the bare die and whack them in there and actually bond them or in place.

and you might be able to see the individual lead elements inside there. There is actually 12 of them in series by I Think 12. So that entire module there is 46 millimeters by 40 millimeters and the actual LED array itself twenty four point, three millimeters squared. Beautiful! I'm trying to get in there so I can show you the individual LED arrays.

So if things shine a torch on there, there you go. You can see as individual little LEDs there's series string a twelve. You can actually see the bond wires going over to each individual LED chip element. Very nice.

There you go, there's a closer shot and you can see the parallel. You can see the metal strip right up the top there where they're all wired in parallel. so you can see the individual bond wires going down each chip element. and then those series strings of 12 LEDs are all paralleled on the top side.

But yet, they're just like, you know, regular high efficiency. LEDs You just buy in your single individual LED packaged products. normally in you know your whatever are surface mount package you are choose. So here's the datasheet for it.

This is the model number I won't read that out, the hose playing along at home and yet 40 by 46 millimeters and you can actually see the array here. It's actually a string of 12 and then mounted 12 of those strings in parallel. Like that and spec wise, the we're talking about a power input 182. What's here? So here? Well these are absolute maximum ratings.

So yeah, you know this thing is designed for really long life industrial use, so you really want to really wouldn't want to push it that far. so you know you'd have to look at your degree C per what all your thermal performance and all that sort of jazz. Anyway, forward current maximum of four point eight amps and a maximum junction temperature hundred and fifteen degrees C And of course you've got to read the fine print down here. You know the temperature of the aluminium PCB is not to exceed 85 degrees.

C So that heatsink that we looked at behind here, you would not want that heatsink to get too well. But and and the actual aluminium back material, There's only a small loss between those two, but you wouldn't want to get that to greater than 85 degrees. C So that's your goal. So that's why they designed this thing.

If you look at the data sheet for it, it's actually got a maximum operating temperature of 55 degrees C and they say it's got a designed temperature rise of about 20 degrees C in continuous operation, so you know 75 degrees C The PCB should be controlled below 75 degrees C So you know they've actually designed this thing properly based on the datasheet. Nice bang on and it looks like the typical operating current 4.2 amps and you're looking at a forward maximum forward voltage of 37 point 5 volts because it's a string of 12 as we saw, so that averages to 3 point 1 to 5 volts per lead chip. Now the one we're looking at here is the 5700 K temperature one, and typically it's going to be putting out at that, presumably at that four point two Aunts 15,700 lumens. So yeah, this thing's only rated for 8100 something once again designed for, you know, a lower rating because it's designed to, you know, really last.

So you're not going to be going the full monty on this thing. and there's a CEO Write it. Just as most cases, it just says a CRI like a minimum value so it's just greater than 70. That's it.

And we've got our thermal resistance I Junction To case here, at 4.2 amps point 1 3 degrees C per watt, so that's reasonably small. so at 80 watts R for example, you'd only be looking at a 10 degrees C rise for the actual lead chip Junction as above the case temperature so that's that's pretty good. And they do make are different in color bins of course, but light and star only at the moment only sell a 5700 K one. And of course the characteristics are going to change a little bit depending on the operating point of this thing.

And here's the wavelength. that characteristics here I Won't go into detail, but this is what determines the color rendering index. So when you get a response of you know with little dips in, you know with one big huge dips in here this that affects the color rendering index. So the higher the color rendering index then you're going to get less of these dips and the more broadband light you're actually even light that you're actually going to get over the full color spectrum like this.

And as with most LEDs they're pretty dumb linear in terms of our forward voltage drop versus current. There we go. Now the thing is, the module itself is actually a hundred and twenty degrees C viewing angle. but the light itself is rated for a hundred and five degree C angle.

So that's what our lenses are gonna be doing here. Whoa! look at that. Beautiful! and we've got some little. it's a bit concave II happening in there.

Go give you a good look at that. Yeah, we've got some concave I'm not sure this shows up on camera. It's a bit weird with all the reflections, but it is concave inside there and it just is one big-ass that feels like last to me. Of course, you need glass to handle the heat.

You know there's no way you're gonna get like a ten year lifetime out of some you know, cheap-ass little plastic lens. This is not gonna do it proper glass. Look at that. Beautiful wonder how much that cost in volume? Hmm.

and I Just powered it up and sure enough, let's have a look. Yep, 82 82 What's there we go. And the power factors about Point Nine Five: I Think it's pretty good. Point Nine Seven: It was claimed at Point Nine Five.

So yeah, it's better than better than what it claims. Nice. All right, we'll just do a quick test here. I'll pair it up there.

I've actually only got two of my new LED lights on. so this is the regular light here in the lab, but I've fixed the exposure on the thing so it does look actually quite dark at the moment. But yeah. anyway.

I've got to fix the exposure otherwise the camera will compensate. So here we go. I'll switch the lights off and as you can see, it's pitch-black Let me plug this top of you and see what we get. Find it, we go.

Move up. Very very nice. Love it! Okay so let's take the back off here. And as I said, there's gonna be no custom circuitry in here.

It's just a mean well brand I know I know that name is like so shitty. I mean mean well. Jesus You know it's borderline one homo, but no, they're actually a really good quality manufacturer of supplies and very reputable. And so it's gonna have a nice high quality lead driver in here.

so it'll just be the mains wiring straight into that and then that'll have your constant. You know your four amp output at the nominal, you know, 37 volt compliance voltage. it'll probably go like, you know, up to 40 volts compliant voltage or something like that. We had that yeah, its silicon down I've got a wedge that open? Yeah? I Certainly these things are certainly tight.

Yeah, there we go is our silicon. Hey, look at that. I should have put an O-ring in there I Mean you know that's a bit. how are you doing definitely? Oh oh really is that? Oh, look at that.

Wow, that's dodgy. I mean yeah, it's got a great quality. I mean well, power supply unit. but it's just it's just silicon down in there.

Oh geez. I Need to. Oh wow. Really? no.

God, they need to fix that. Come on. No, that's that's not good enough at all. Thumbs down to that And you know what? Here's the other one they sent.

Listen to this. Have an open this. Yep, Yep. loosey-goosey in there.

Ah, that just does not cut the mustard at all. They need to really fix that damn thing in place. I Mean look, it's got the proper lugs on the thing. To me out the thing down.

Gone to all trouble to custom make this. Just tap some damn holes in here and screw the thing down. Unbelievable. They've gone too.

You know it's otherwise very. You know, well, design like it's quite. You know they're using a top quality supply and it's all you know. It's built like a brick.

Danny and it's all properly thermally rated and everything else. but ah, just let down by that unbelievable No. Look, they tried to put some double-sided tape on the bottom here and that's just real crusty stuffs. No, the good quality stuff not fail.

So here's the meanwhile: power supply: Hlg a Th 42 and yeah, as I said for TN there we go. Just over 40 volts compliant voltage 42 volts and this one's actually 2 amps. So they're actually running this at less than half of what this thing, what the lead module itself is actually capable of. So you know.

but that's what you have to do when you design. You know, high endurance products like this to last a long time. You can, you know I can't necessarily run them at that huge current you could, but you probably need a bigger, better badder Us Heatsink and all that sort of jazz now. I Would have loved to have shown you inside this thing, but unfortunately this is the dead giveaway suitable for using dry, damp, and wet locations.

It's not not suitable. It is suitable. What does that mean? Well, it means that it's potted. and here's the current out adjust and the voltage out adjust.

And if we take that off to the potted block, there we go. It's that, sort of, you know, softie kind of It's you know, that sort of rubbery, softy, kind of potting silicon potting compound. But yeah, I mean I'm not gonna go and destroy this and dig it out just to show you inside there. and anyway, to be hideously ugly.

So sorry about that. Why? I Can't show you inside this thing. There's the pots right deep down in there and that's it. Mmm.

But anyway, Lean World didn't make our decent supplies, so no problems there at all. And the other thing is the earth wire. here. You know it's heat shrunk.

No problems there at all is actually connected through to the case of this thing. It's not a double insulated supply and we can prove that by poking that on there. Okay, that's fine and dandy, right that it's earth. But the fact that then this, the case of this, is not solidly earth to the case of this: I'm not sure if that's even legal in this country.

I if anyone knows ins and outs of the regulations and not stuff like that. Sorry, I don't know. Off the top of my head I don't have a copy of the various Sus standards and things like that, But yeah, that's that this thing. it needs to be properly bolted down to here and I would have liked to have seen the earth go off to the proper load mounted on here with the shake proof washers and then a second wire of course going off to the module itself.

So yeah, don't like that at all and also doesn't help getting the power out of the power supply that this dissipates a fair amount of power as well. and that's critical to the life of this thing. just like the lid module is. and to just stick that in there with tape and not actually mount it properly to try and get the heat out there.

Now, I've had this thing on for like over an hour now. it's just sitting there. I've got no air conditioning on in here, so it's not like any extra airflow or something in. Let's get our flow now.

Eight beautiful little thermal camera and we're looking at 45 degrees sees, yes, like, right in the center there. forty four if we look at, you know, the bottom case down there. It's not a huge amount of cooler down there, but right down in the core there. as advertised, 20 degrees C above the ambient temperature here, which is about 24 or something like that.

So yeah, pretty much a spot-on as advertised. Nice if you want to see down in the guts of it. I'm not sure what the glass is gonna do there, but well. I doesn't that look funky? Looks like some alien spaceship or or something like that? That's just beautiful.

Well, but I should use that as like the screenshot for my video. What are the thumbnail for my video? What do you think? I'll capture that image? There we go. So that's all we've got for this puppy. I'm sorry, couldn't show you inside this.

so nice power supply and well, not much we can do with the lead module. Really is how to look at the data sheet which I'll link in down below By the way, if you want to take a look at it. and I'll link in their website if you want one of these puppies. I mean they've got to fix this issue of just flapping around in the breeze in here.

That's just crazy, but if they did that, it's just these little small things like that, you know it's otherwise. it's quite a nice unit. I like it and I'd probably buy some more for the bunker. but yeah, they've just got to fix that so we'll see what they have to say about that.

and I'll let you know. And if you liked the video, please give it a big thumbs up if you want to discuss it. All the links, all that stuff, err down below. catch you next time.

Oh, just an update. I Heard back from Frederick and he said that the guy who assembled these these were specifically our samples for me. They didn't know that I'd actually opened them up. The proper ones will actually be stuck solid in there.

You cannot remove them. They will be so lovely stuck. I Didn't mention anything about our bolting in there, but yeah, apparently this is not normal. you.
