Hi guys, we got another lead lighting video because I'm about to install some lead lights here in the lab and uh I thought I'd just do some uh measurements, get it on camera, try and show you the difference. although it is hard to get that on video, but we'll try and get some measurements anyway. Now I've done a previous video on this. if you haven't seen it, it'll be linked down below and that was with uh Doug Ford from Doug Ford analog designs where we installed some of his cool uh, lead lights but it's not enough I need some more.

So what I've got at the moment is my lab is actually quite dark. It's a, you know I don't have my lead lights installed at the moment. All I've got is my uh regular compact U sorry uh regular uh tube fluos up there and they're um, pretty new. um NEC quad uh phosphor ones at 5,000k color temperature and well, they're not bad but it's still I've got two there and it's still, you know and more spread around the room.

it's still not enough light. so I've got remote controls for my other lead light. So when I shoot videos like this is fine for just hanging around the lab. but when I shoot videos I turn on.

I've got uh the two lead panels which we saw in the previous video so I can turn those on and woohoo! So this gives me uh nice flood filled uh lights that sort of come in from different angles and from behind me and light up all the stuff on my bench which is really really quite nice. and if I do need more than that I've also got uh, the ones Doug manufactures in his own Factory these um strip LED lights up here so I can turn those on as well and they're directly two of those directly above the bench so they just come down and light it all up but unfor. so these are all uh three? 4,000k but my uh, fluos are 5,000k but I've got see these new lead lighting tubes from AI They had them on special today so I went down picked some up. they are 25 bucks each.

um you can actually get them uh cheaper than that on eBay but they're you know, who knows what brand, who knows what quality. these are from a company called Mala Light in Germany and um, they look, you know and sound decent quality and they are 4,000k So I thought I'd try them out and uh, see if we can get some measurements so I can replace all of hopefully all of the uh, compact all of the fluo tubes in the lab with the same color temperature lead lights and they're I think 36 watts in there at the moment. When we get them down, we'll check these are only 18. Watts So um, they're rated for 1700 lumens each so we'll give them a try, get some measurements here on the bench and see if they make a difference.

Anyway, it's worth a go. Let's go Boom! Now here's the ones we're installing from: Uh Mal light or Mu light or however you want to pronounce it I'm sure my German viewers will correct me on that and uh, no, they're not made in Germany they are made in China But at least they're a reputable uh manufacturer I believe, so they should be. You know, fairly well, uh, speced, and you know, fairly decent, uh, quality. We might even, uh, eventually crack one of these open.
but I'll leave that for another uh video anyway. um, 1,700 lumens 18 Watts So they'll be hopefully replacing 36 wat uh, strip fluo so you got to keep that in mind. You know much lower, um, energy, uh, requirements and uh, you know, there we go. They reach 60% of their claim Light Within 1 second, etc etc.

30,000 hours so they claim and 15, greater than 15,000 Onoff Uh Cycles these are 4,000 uh K neutral white, uh color and Lead lifetime of 30 years at a around 2.7 hours per day or so they claim. Anyway, these are rated for 230 volts. Uh, mind you, I've got closer, like over 245 volts here in the lab so I'm not sure how that will affect the light I'm really on the high side here of the upper limit of the mains voltage here in Uh Sydney in the lab. Anyway, they have a Uh CRI of greater than 80 there and they draw 97 milliamps at 240 volts and they weigh 285 G if you're into that sort of thing.

and uh, there we go. There's a energy chart I'm not sure, probably a standardized energy chart or something like that. I'm not sure what A+ means I haven't investigated that at all. some sort of European uh Union thing I guess standards and uh, they are made manufactured by Mite for specifically for Audi stores to our stringent quality specifications.

If you're not entirely satisfied, 60-day refund. There you go. I can Chim them out for 60 days and I can return these suckers and made in China And that's their website. Uh M light or licked de however you pronounce it sorry, that's uh I need to work on my German pronunciation.

but these are the ones we're going to install and they are, uh, completely, uh, frosted. Now a lot of these are clear, but you can see that it has extra frosting on that side, but I can't see any of the leads on the PCB inside there. I can't see anything through there. So um, you have to install these the right way up.

of course. otherwise the you want the light bouncing down, otherwise it'll be bouncing up off the reflectors in the top. but uh, I'm not sure how much of a difference that makes. But anyway, yeah, they are completely frosted now.

I've got my light meter here, um, pretty much directly under my dual strip Fluos up there. and as I said NEC quad phosphor uh 36 wat 5000 K basically Bally at the top of the range Fluo bows and I'm getting about 390 Lux here on the bench. So I'll keep this in the exact same spot and we'll replace those two 36 w ones with two 18 wat lead 4000k uh uh, fluo replacement and see what we get. So let's yeah, let's call it 390.

I don't have my other lead lights on if I do switch those on my main lead lights, you'll notice that Boom! it instantly goes up to 640 on my bench. And actually and if I turn the other ones on above hello Wireless there we go. wo up to almost 950. There you go.
So I'd be you know, pretty happy if I uh get that to jump up to I don't know, you know 500 to 600? it' be fantastic. Um, but yeah, we'll see. Okay now what I'm going to do is just check my what uh my camera tells me is the white balance value from this white sheet of paper I've got here. it may not look exactly white.

my camera is fixed to a fixed 4600 white balance at the moment, but let's uh, change that I need to stop and you'll notice that if I set the white balance here, the camera will actually tell me what it thinks that white balance is. It should be 5,000k because that's what the NEC tubes are rated at. So if I hit set white balance, there we go. Yep, spot on.

It definitely says those NEC fluo tubes are 5,000k And of course, when you install these, you get one of these little, um, shorter uh starters. It's basically just replaces your existing starter. it's got a short inside like that and uh, we'll explain in the uh, previous video I've LinkedIn exactly why and how this works. But anyway, just simply replace it.

Not a problem and I had the lights out when I was replacing these bulb. so I couldn't quite see which orientation it went in. And of course Murphy says I get it back to front and you can see that the light shining up into the trough up there and reflecting back off. um yeah, oops, just need to rotate that so it points down obviously and Just for kicks.

we'll uh, actually measure that with the light shining up into the trough and reflecting back down. there you go 135 Lux on the bench. Let's see what happens when we, uh, rotate it. we'll get significantly higher and Bingo there you go.

gone up from 135 to around about. you know that 190 odd figure. So don't install these upside down and there we go. look at that.

um, quite dis appointed. It is less I expected, at least equivalent. Uh, really. but no, it's not.

um, you know about. let's say 310. Lux there. So we Dro from about 390 from those dual NEC quad phosphor ones uh with at 36 Watts but hey, these are 18 Watts So um I don't notice any noticeable difference in the lab here.

So really, essentially, to my eyes, very equivalent. uh, in terms of light? Sure, I'm not going to be getting more, but still, probably a worthwhile replacement giving that they're um, they're only 18 Watts as opposed to the Uh dual 18 watts each as opposed to 36 watts each in the other tubes. So really, I'm probably just a worthwhile upgrade there. Plus I Also get the bonus of having the correct Uh color light temperature as well, which we'll measure now.

All right, let's set it and see what we get. We're expecting 4,000 and we get 4200 near enough when you combine it with all the other lights in the lab mixing in with these nominal 4,000k lead bulbs. So that's pretty good. And just for reference, here's the NEC quad phosphor tube As you can see 37 Watts not 36 as I thought uh, 5,000k made in Japan and we'll just check for safety of these tubes to see if they're correctly uh, designed or not.
Well, you know I assume they are correctly designed because um, you can't import legally import the dangerous type anymore I Won't go through the differences. we've done that in the previous video, which will be linked down below, but we expect a short only on one end, so let's take a random end. Yeah, there we go, All right, and we should not have a short on this end. and of course we don't, so that is the safe type.

Beauty So there you go. I Was a little bit disappointed with those, but uh, 1,700 lumens and I believe the NEC ones are rated for like 3700 lumens nominal output or something like that. So really, um, yeah, these give slightly lower Lux output actually on my bench uh, surface itself, but probably equivalent here in the lab I don't see a huge difference really. So um, probably not good enough I still need I have to get some more of those lead panels up there from uh Doug cuz they're they're really super bright.

they're like 60 WS or or something each. They're fantastic, so I probably need another two of those over the bench plus the two backlit ones. uh, on this side so they can backlight. but these ones probably going to be quite good for the rest of the room considering that there are the 4,000k the color temperature I need So therefore I'm not.

you know, mixing the 5,000k Nec's with the Uh 4,000k lead light. So yeah, I'll probably go replace my 37 watt tubes with these 18 WTS and save some energy too. Eh, let's not get into the whole uh, cost benefit and payoff period and all that sort of stuff I Like them I think they're pretty cool. So anyway I hope you like that.

Catch you next time.

  1. Avataaar/Circle Created with python_avatars Soarer says:

    one major point is that the led only fade about 5% over their life compared to around 50% on the conventional fluro tubes. so the output of the led's over time with led will eventually beat the fluro's.

  2. Avataaar/Circle Created with python_avatars Sean Zappulla says:

    I use the 2 NEC 5000K tubes in one of the bathrooms above the mirror and it's very bright. I would like to see if NEC does a L.E.D. version

  3. Avataaar/Circle Created with python_avatars Green_Man_5 says:

    why do you say lead not L.E.D.

  4. Avataaar/Circle Created with python_avatars Cees Timmerman says:

    The "extra frosting" is probably white plastic that holds the LEDs.

  5. Avataaar/Circle Created with python_avatars FrontSideBus says:

    1700lm? Normal 36w 4 foot lamp is like 3300!

  6. Avataaar/Circle Created with python_avatars RandomTorok says:

    Do these just pop into standard fluorescent tube fixtures?

    This "energy chart" is part of European union bureaucracy – all energy consuming goods even buildings !! have to be marked by "chart of energy demand". Even classic light bulbs …….. THIS KIND OF THING IS WHY EUROPE IS A CIVILISED PLACE TO LIVE …. AND NOT MAD MAX RETURN OF  THE THUNDER DOME LIVING LIKE THE USA HAS 

  8. Avataaar/Circle Created with python_avatars ScribblingOnTheWalls says:

    I fell in love with LED bulbs very quickly after years of those godawful CF POS energy saving bulbs.  The only downer on them is how freaking much they cost.  Got some of the Phillips master 75 watt equiv bulbs as the main lighting for several rooms, some no-name 60 watt equivs for the bathroom and upstairs landing, and a couple of the no-name 40 watt equivs in a couple of table lamps.  They're brillo.

    WTF 15000 on / off cycles,  never heard of that spec
    should be like 20 years unlimited on /off cycles

  10. Avataaar/Circle Created with python_avatars VWestlife says:

    Saying LED as a word just sounds wrong to me, because it's pronounced the same as lead, a toxic substance that has been removed from various items over the past few decades (gasoline, plumbing, solder, etc.) due to its danger to public health — so that's a very negative association that LED lights are trying to be the opposite of, due to their energy savings and lack of the similarly toxic mercury found in fluorescent lamps.

    So, maybe in another generation when nobody remembers what lead is and how dangerous it was, then manufacturers will start pronouncing LED as "lead", but until then, they will say "L E D" to avoid any association with lead.

  11. Avataaar/Circle Created with python_avatars Fabian Köhler says:

    A+ means extreamly great A++ ist the ultimate

  12. Avataaar/Circle Created with python_avatars Andre says:

    Very nice this option, i want to implant this idea!

  13. Avataaar/Circle Created with python_avatars Gerjaison says:

    I think the correct terms is EMI (Electromagnetic interference), did you purchased from Ebay, also where are you from? If so, probably not EM immune! Otherwise they shouldn't because it is illegal to sale something not EMI tested! In Australia anyway.

    Hi Dave, did you measure the RF/HF emission from this pulsed light
    cheap leds from china are great rf/hf transmitters

  15. Avataaar/Circle Created with python_avatars Blood Reflex Entertainment says:

    ??? 5000k refers to the color, not the brightness.

  16. Avataaar/Circle Created with python_avatars Akin Turhan says:

    The ALDI stores in the USA that are in New York State do not carry these lights

  17. Avataaar/Circle Created with python_avatars Misty Moo says:

    Just install some halides and be done with it. Jeez.

    5000K Lighting- What are you trying to do- Burn a Hole in your Retinas?

  19. Avataaar/Circle Created with python_avatars Jesse says:

    Man, only $25? that's a wicked deal, usually regular led lights seem to be around that price or more. (the round socket ones)

  20. Avataaar/Circle Created with python_avatars MattHumanPizza says:

    Really enjoy your videos, they are usually over my head in terms of technicalities yet the presentations and blog are fascinating, thank you

  21. Avataaar/Circle Created with python_avatars alecjw11 says:

    At 04:34 that's an efficiency rating: They have these labels on basically everything which uses energy over here (UK). You get them on light bulbs, fridges, ovens, boilers, and even houses and public buildings. I've usually seen them going from A to F though, i had no idea there was an A+ and A++

  22. Avataaar/Circle Created with python_avatars DOCa Cola says:

    first time i have ever heard of müller licht here in germany… 🙂

  23. Avataaar/Circle Created with python_avatars Stuttgart says:

    ALDI is mostly cheap crap, but usable.
    regards from germany 🙂

    would these led tubes work thru quickstart type ballasts?
