You could do 3 logic pucks at 70w with those drivers. It's what I did with that same driver and I'm really happy with it. May even work on you fixture

That's a good match but it won't be any difference in spread really.

What I need to do is just bite the bullet and shorten the width of my fixture from 30"-24". It would make the light spread so much more even in a 4X4.

Yes it's true it works, but it's spread could be better. It's not going to waste any work I've done and won't be dismantled. I'd literally just remove the cobs, and fill it with boards or strips. I could put the cobs back on in a matter of minutes if I wanted to.

I would leave the cobs and drivers alone and just run some strips with another driver. It took you a while to build that and it would be a shame to dismantle it. Looks like it would still be working fine. Maybe add some reds or exotic blues to the overall system

@welight : can you maybe give some more details on the phosphor covered red chips. Im trying to spec a driver for the red channel and i i nt know the max drive current. As per your email you stated they were 0.65 W chips, and 2.89 ppf/w. Does that mean they are 48V and around 700mA max drive current?
How hard can you drive these chips? Should inhave any specific concerns as to max Temps or similar?

As a matter of fact i would really like this info (max drive current and fV) on the blue channel aswell unless its the standard 28V, 1000 mA.

Oh ok. I didn't realize you were looking for a more even spread. Those pucks do shoot the light out extremely wide but without seeing your space, it's hard to tell if it would be suitable. I know you can drive 4 of the atreum 144.2 panels in series so maybe look at those too

@TEKNIK
amazing what you are doing, i have some solstrip left : 2 channel nichia 5000k 97cri + 660
2 channel 2000k + cree xd 16 @3500k
if you need one of each for doing teste i would love to send you one of each, im pretty confidente ontheire amazing spectrum :D

i would love you to tell me more about the spec of the LH351H Far Red and 660

very nice to see someone witch has material to teste everything

Ya those are cool but won't fit NY heatsinks. I'm gonna go with the Meiji 288's.

Hi Grisby, the nichia cri97 is pretty awesome as far as spectrum goes, they are lower in efficacy than standard models but I believe they will make for a better overall quality grow, I haven't tested any of the Samsung chips you have suggested yet, I tend to find that data sheets are not right and you often need to deduct 20% from the claimed efficiency on data sheets. One of the main reasons I am conducting test for you guys is so you can learn how to use IES files, efficiency is not as important as an overall build design and with IES files you guys will be able to design your builds on a easy to use program on computer.

@welight on those 560mm ssk-1560-3090 is there any other offer that's the same thing but just with maybe 4-6 blues and 12-16 reds amongst the 112 diodes too? Or any amount of reds and blues as well?
Do you have to use 2-3 channels to do that no matter what or is there some diode you could use that handles the same current as the whites?

Those are 3030 chips, I have tested single reds and blues in 3030, there is no advantage to running reds and blues in a 3030 package when you are mixing a spectrum, it costs more and no gain.

So you'd have to use at least 2 channels then and use it for the reds and blues in a different led type?

Power leds and mid power leds are quite different. This is why on a solstrip for example there are both mid power and power LED's. The high efficiency reds simply do not fit into a midpower package.

Currently the SSK-1560 boards are all about white, we tested other 3030 leds in colour and they dont really have the punch that matches the whites. The 3 channel Solstrip-BR is the compromise that is tuneable or channels can be tied together. Are you wanting to have the whites and colours all on the same driver?

Growmau is a mate but I dont get the logic puck any more than I get QB96, making COB format devices in 200LPW+ chips negates the benefit of mid power which is to spread the light across the canopy, you get the same shadow/deadspot/hotspot issues of COB's. You gotta spread the light across the canopy to max the yield, The future is strip imho.

Hi Rocket
I will get this to you today

best 560mm strip for me will be:
3 channel:
1st: 1 row of 96 nichia 757 @4000k 80cri
2nd: 1 row of 12 cree xpe2 @465/.485 & red 660 ( 3 blue/ 9 red )
3rd: 1 row of 4 cree xpe2 far red

i dont know for the electrical part @welight , we are in touch anyway but, this strip like that can do everything, and will be at 100w@75% of theire max power, i have already the beasty heatsink for cooling that passivly!
My opinion is than the nichia 757 are better for penetration than samsung, theire are not playing on the same field ( 0,3 middpower led vs 1w led), and new cree xpe2 , i think we can try to get almost the 3umol/j :D
have the efficiency of the nichia 757 4000kin term of lm/w and some bloomboost spectrum with the 2nd channel + the emmerson effect dimmable ;). thoses monocolore led will increase as well the global cri and decrease the cct , witch is perfect for bloom!
would love to get some of them to make structure for friends and growshop!
