we have a boost board with 5000k and 4 pcs of XPG-3 450nm if that helps https://www.cutter.com.au/product/ssk-1560zge-xx-2835cr/ Cheers

Just built some interesting boards if 4k is your thing. Cree in 4000k 98 CRI and Cree XPE-2 Far reds I would say nice veg board, Good SPD balance of Blue to red to keep stretch from getting out of control Parameter Value CCT 4114 K Duv 0.0001 CRI (Ra)(R1~R8) 98 CRI...

301b for 288 pcs and reds for $19.... not possible

rivets are ok if your holes on the board have safe zones, ie not no copper traces around the holes that will be cut into by the rivet. NEVER use super glues, these are cynoacroylates, these outgas and can create VOC's which will shorten your led life. best option is to drill and tap and screw...

I find the samsung data a little confusing. the datasheet says 3000k 80 CRI is min 168 lpw at a non listed drive current, 187 LPW at 450ma and 231 LPW at 1000ma, this cannot be correct and I assume it must be back to front, any ideas, on that basis its is hard to know what the umols/j would be...

got it, the link at the start of the thread did not show that

cool no worries, I could not see that on the specific product listed

interesting how the china lights continue to dumb down, 660nm, picture looks like Osram but they dont state that, the high efficiency is white/red lights but is driven by red, but best performance is only best deep red, seems like they feel if they dont say they can drop in any old deep red, so...

what is a HIT?

Interesting that Samsung building boards dont want to use a better red

for those that like this stuff, our new placement system running Cree HI FI 98 CRI strips

email sent sorry for delay, been installing new SMT line so behind on emails on the upside we will make you boards faster....:)

Nichia will release new leds based on the GE Trigain phosphors which will lift efficacy of 90 CRI to the same level as 80 cri if you need help making strips, we just commissioned a new smt system

I have your email, will advise today Cheers

you have to adjust the light on ies import to its actual size

Thrive chips have a max drive current of 80ma which seems quite low and would possibly explain why thrive strips have lower max rating, 98cri chip sets are generally lower drive rated, Cree 2835 Hi Fidelity 98 CRI is max 150ma as opposed to normal Cree 2835 HE at 480ma

The benefits for water cooling are to run chips hard, but keep them cool to maintain efficacy. You need to offset the cost of Water Cooled infrastructure against running less boards, that will run harder. This is 1200watt of strip, delivering 2800PPF. Also has the advantage of running strips at...

we have 560mm strips in 3 channel https://www.cutter.com.au/product/ssk-3560br-v2/ cheers
