Our 272 is robust but sticking it to plastic is probably not where I would go. For simplicity and fan removal, 3 mm flat plate will work a treat. The only fan you want is the main one you likely use in your area to just push air about. Most panel designs make assumptions about the rooms having...

refreshing to get actual info after the fact, im guessing these were not aluminium boards

I put some strips into my production area with old funky drivers, mounted to timber, driver failed within a day due to heat, mounted the next driver onto alu plate, then back onto timber, hasnt missed a beat since, still runs hot but dissipates through the alu plate. Maybe check the...

5000k and up meaning 5700k or 6500k, did I misread I thought it was veg not seedlings/clones

For Veg, I dont see any issue with using 4000k, this is used by many on this forum and is well balance red to blue to avoid stretch which can occur if you move into 5000k and up. If you want stretch via control then 730nm give the shade avoidance effect so can be used to induce stretch and you...

So my take on this could get wordy. Two points Phosphor coated leds do blend as a colour. If I build a board in equal parts 3000k and 4000k I get CCT of 3500k Monochromatic no so much, If I have 730 and 660nm on a board, spectrally I will have two SPD peaks of 730 and 660. Red and blue will...

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
