Alrighty this will be my second DIY led flower light build the light will be built primarily for flower. But I'm using higher cct this time. So it could be used for veg too. But it will be my min flowe light in number 2 flower tent... and will be run through wireless switches from sonoff. Controlled with my phone. My first build. (10) Samsung F Series Gen 3s 3000k f562b in parallel, on a HLG-480H-24A driver. Maxed slam out 25.5vdc @20.00a 504watts. But I'm not running it that hard. (5) Samsung Sunboard strips 2700k 50w 96 Lm561c S3 diodes @24v running on a HLG-240H-24A driver. (4) custom made Red strips. 120 diodes. (60) HE Photo Red diodes, and (60) Far Red diodes. On a copper PCB strip. The diodes are alternated between the two for even blending. And they are run on a LPV-60-12 driver. The light rocks flowering. Yield, trich production, and penetration is very good. I'm not real big on super low voltages super efficient. I like bright ass lights that put out large frosty nugs. The heat sinks I made myself. I used thick wall 2x2 square aluminum extrusion tubing. 24" long that I cut on 3 sides. Every inch. And then mounted the strips on the uncut side. And installed a 45mm×45mm PC fan inside on one end. So it blows through the tubing. Keeps the strips extremely cool. Remote mounted all drivers in their own box outside the tent. Before the sunboard install. Tested on HLG320 And now for the new build. Gonna be a mix of cobs, strips, pcb led boards. In an array of color temps. Strips will be delivered tomorrow. New build.... (4) Samsung F Series Gen 3s in 4000k run on a HLG-185-24A (3) Samsung F Series Gen 3s in 3000k run on a HLG-150H-24A Or all (7) on a HLG-320H-24A I havent decided that yet. Arrow is out of stock on both the HLG185 and HLG150 drivers. The cobs are just extras I have laying around. So why not use em right. 1 is brand new. 2 I've used for a old veg light I built. (3) Cree CXA3050s in 4000k And I havent decided if I wanna use the el cheapo drivers I have laying around or buy new ones yet. If I run them on this driver. They will be in parallel all 3 run at 600mA @37vdc 22.2watts each. I have 4 of these drivers. They were hooked up 1 cree cob per driver. One cob got broke. But the drivers arent adjustable. So it runs them at 1800mA @37vdc 66.6watts and I dont wanna run them hard. Even though they max at 2.5a and are typ ar 1400mA. These arent the most efficient cobs. But I didnt pay for them or the drivers. So why not. And I'm also possibly gonna throw these pcbs in the mix. They are (40) double led diodes. In 4000k run in parallel on a 150w inventronics adjustable driver.. I believe they are Seoul smd3030 leds. But not certain. But they both run on the inventronics 150watt driver at full power. And stay pretty cool. But if I use them, I'll put a POT on the driver to turn em down some. The driver is present to 4200mA at roughly @35.7vdc but is adjustable from 385mA-5600mA and is roughly 90.2% efficient at full load. So overall this light should light up some plants.
