Beat me to it, I recognize those strips and mixed spectrum.

ok cool, I think in my 10 strip build I got a factory mixup two of my strips appear to be something other than 3500k lol

4x2700k and 2x 5000k averages to 3466k couldn’t you have just used all 3500k? or does averaging work like that

How mine looks on minimum. First (from the top) and 7th strip appear to be a different spectrum.

I could but that’s not what the guy wanted. I just designed and built mate.

looks like two 2700k or 3000k if they have it

Your 3500k look to be all 5000k bro

#551

prob just how it looks due to auto white balance

I don’t even care what spectrum they are, they are working fantastically for me :smiley: lol.

I hate to say it, but looks like you have 2 3500K and 8 4000K. That’s odd, either way they are working. Can you tell a difference in the diodes when they are off? The coating makes the diodes look different, the 5000K are yellow while the 2700K are orange.

The point is. No matter what’s in it. It works bro and works well. I’m seriously tenpted to get a sample pack of megacrop too from your results.

@legalcanada now you pointed it out. May have made sense to have a slightly different arrangement.

3x3500k and 2x5000k for the first driver to act as a “veg” light and kick on the other for another 3x3500k and 2x2700k. Well pointed out and you educated me as to the maths of Kelvin. Appreciated

I’d say the 5000k are more blue/white than yellow bro.

I’ll snap some pics of the diodes tonight at lights off :slight_smile: TBH for my cab size, I don’t mind that they are in the cooler spectrum as stretch is a big deal lol.

They are X1 strips, all of them are labeled as 3500k according to the solstrip sticker.

@anon58740919 So do you find that having “on board” drivers like that increases temp much?

Watch this “accident” be the reason you smash it in such a small space. All the strips I have are x2’s but the diodes are all still lm561c so can’t see that much change occurring from manufacture

he was referring to the coating on the diode not the output. here’s my 3500s

X1 VS X2
Same diodes, better PCB layout/design. X2’s have better thermal characteristics due to more pad size and thicker traces.

i’m still thinking you have 8x 3500k and 2x 2700k and it’s just the auto white balance playing a trick on us. i’m going to go take pics of my lamp with different white balance settings and see. sorry for shitting up your thread cola lol

I always build my frame from aluminum so they act as a giant heatsink. (Also works as an Earth for your drivers for US folks) I personally don’t think they run that warm. (They’re remote in my own setup with 3 in a small enclosure that barely kicks off any heat even running everything
