yes with large surface area MCPCB you will struggle to get the whole board heated with hot air gun, at best it will be useful for repair of single diodes, thats why you really need a plate and gun together if you want consistent reflow and ability to repair

this one is a special 4k 95CRI, but the 5050 are available in all the same spectrums as single die 3030, 2835 etc cheers

yes I thought the numbers without the driver losses kinda wierd cheers

yes watercooled, so the idea is to use less leds, crank them hard, but maintain efficacy but running cool at higher drive with active cooling, less leds, higher penetration with 5050 leds and as you can see the new Cree K Class 5050 is still over 3umol/j at 150ma. 5050 as they now start to...

I agree, with 5050 less can be more, 1200w, 2800PPF Cheers

To be honest, I am hoping the leds sent to me from Bridgelux are just the wrong leds, a mistake was made. I can only provide data as I have it, the test was done on just the thrive 2835 chips and that was the spectral and CRI result. I am hoping that BLX send me correct leds and that when tested...

If your using MCPCB then I would always use a hot plate if you do not have professional production equipment, you can more easily observe the reflow process with a hot plate to gain some experience about the reflow process and also move leds while solder is molten if needed, if you use FR4 then...

Sure can. No real complaint about the spectrum

yes me Cheers Mark

The on board design/structure of the diode layout will play into the max currents on strips All leds that offer 95-98 type CRI numbers will be LOWER efficacy than general white chips, the energy required to convert phosphors is more difficult when the % of red increases as in HI CRI. in 2021...

When I tested the Thrive Chips, they at best came in at 93-95 CRI in both 4000k and 2700k, Im currently trying to return these to bridgelux as they fail specifications. Same equipment I have tested Nichia Optisolis, Lumileds min 95 and Cree HI FID, and they all tested 97 and 98 CRI 'straight off...

Cree 2835 HE in Hi Fidelity are 98 CRI right out of the box, the thrive chips I got from BLX unfortunantly were not below is the 4k chip results...

Just like normal copper fill but expanding from the heat pads and connecting the anode and cathode pads of consecutive diode footprints instead of vias (vias drawen "under" them for KiCad to know they are connected). I will post the new design today probably, maybe tomorrow. YES Copper POUR is...

The prolight design is now quite dated and is a throwback to the old LUXEON LUX leds that always used an active slug, many of the crappy early chinese lights use that old P2 style design chip that also used an active slug. This is rare to find now. I would think if you want the best solution for...

Strange par map on that light, is that conical?, Kinda would make sense if the light was over a single plant and your christmas treeing it

just lacks a vibrate button

interesting length?

strip efficacy does not change if 24 or 48v, just the current drive required is twice for 24 vs 48, assumes same chips used cheers

where did you see it was 100Deg beam, datasheet on both says 120Deg? Cheers

yes right, the recent Cree upgrade is great to see and good they continue to improve this chip, along with its max 480ma drive current and more improvements to come, this should become THE chip for grows cheers
