Samsung H series strips, Arrow seems to be blowing them out! what a deal!

Have you checked ebay? "Ucandoit" I think is his handle name. He sells double sided thermal, otherwise I've used this and it works well.. gl

Canadian link but, I am on my 3rd roll of this tape, you won’t get a strip off without destroying it, seems to have good contact. I don’t use screws.

So , I have been lurking here on this thread, and a couple similar to this. And one thing I am a bit confused about is the color=K of the strips used?
I want to build an all around full spectrum veg/flower fixture.
So the 3500K strips are for a vegg, use?
And the red660nm, deep red7__nm
Is the diodes suppling the flower spectrum?
Thank you in advance

The K means Kelvin, 3500k is the norm for full cycle. Most qb board style lights are a mix of 3k-5k with 660nm reds sprinkled in. Doing these bar style diy you can pick whatever. Higher K , 4-5k= more blue in the spectrum which keeps plants shorter w/ tighter internodes. Use during seeding/Veg stage.
Lower K, 2700-3500k= more red in the spectrum which promotes growth(stretch) and flower. There's more to it but that's the basics.
for example I veg w/ a mix of 3.5-5k and add some royals 450nm to keep them shorter/bushier. Then switch to 3-3.5k for Veg and add 660nm/ir/uva/b during flower. Hopefully others chime in , everyone has there own way.

There's a thread by @ilovereggae and he uses Vestas/bridgelux that have different spectrums on the same strips. Can switch from 5k to 3k I'll try to find it

3500k is fine for start to finish with nothing added. Here’s the link mentioned.
Bridgelux Vesta super tuneable strip build
it's finally done. 8 Vesta 2ft strips. Each channel has its own 185W 24V driver that will run up to 975ma. this let's me run either 2700k or 5000k on its own or in combination to get anything in between. While these strips can technically take full blast on both channels, I will only run...

You can use most of the different spectrums for vegging.
I've used 3000K, 3500K, 4000K and 3000K + 660nm + 720nm for vegging. They all work.
4000K is great for vegging. Keeps the plants short and squat.
I've haven't tried 5000K yet for veg.
A good all round spectrum for veg and flower is 3500K .
I don't advise 4000K for flowering. Too much blue, in my opinion. I found it produced more leafy buds.

So a strip build of just 3500k is good germ to harvest.
I currently have a Hydro-Crunch burple fixture. It is really lacking in power. And I have the soldering skills and good tools to put one of these lamps together, just haven't done one. And I am currently in my first grow, 3 weeks from flip, so I want to see what kind of trouble I can get into with a 4x4 build.

So have been looking at the ARROW ELECTRONICS website. And as another member here had said, it is maddening on a mobile device.
I want to build a fixture for my 4x4, what is a good middle of the road strip, using the 3500k chips, at or above 72 diodes per strip. I want to run 380 to 400w for my tent.
Thank you in advance

For sure, I did a 3500k strip build for just the occasion, I had to add I think 12 4K because I ran out of 3500, think there is a pic somewhere in this thread already.

Arrow has some old L09 strips for under $4 each. Someone might have a link to something comparable price wise but better. These are 3500k and are the strips I used, 54 of them.

54 pcs for a 4x4 wow.
That's a lot of wiring...

Na, it was in 5 x 6.5, I’m going to spread the bars more for the new room. Yeah wiring was killer, fixture is 4.5 x 5.5 right now.

What about heat? I mean 30w/Sq2
That must use a pretty robust sink?
Do you have a pic of the unit?
What driver did you use for it?

I got this one from a shop near my house. But do you think that its gonna work? They say Nothing about the heat capacityHave you checked ebay? "Ucandoit" I think is his handle name. He sells double sided thermal, otherwise I've used this and it works well.. gl

The double rows I use actual heatsinks from alberko a company near me. They have website https://heatsinkonline.com/
For less wattage 20-30w I just use aluminum U bars, not pretty but who cares. I meant 16 strips before 8 bar.
I've done a few lights but here are the 2 used in larger areas. One in use now I bought a shell from PLC and did some mods to make the strips fit. That one has the double row strips , but also a bunch of singles "q-m-h" that I doubled up. Drivers are meanwells 240w-ab. And a couple MW hlg-150
16- L09's - drivers are Autech 400w x 2
