We've gone back to "V1" (LM561C S6) LEDs, because they have the same IV curve for 3000K and 4000K. An equivalent light using "V2" (LM301B) LEDs would have a brighter 3000K than 4000K.
We've increased the LED count to 144. This maintains the same or better efficiency of our V2 panels. (Approximately 2.35uMol/J)
Two channels, 3000K and 4000K, for a 3500K spectrum. Simple, straightforward grow light for a small area. Let's say, 50x50cm. Full cycle 3500K.
Using a 90% efficient Mean Well LRS-100-24, the light outputs 75W, but can be dimmed using the voltage adjuster. Be careful not to adjust it without a watt-meter, or you might trigger the overload protection. Passively cooled.
Dimension of light is 50cm x 10cm x 1cm. Driver is not waterproof and should be kept outside of the tent. Dimension of driver is 13cm x 9cm x 3 cm. Default length is 1.3m of AC cable, and 1.5m of wire between the driver and light.
Just some holes on the heatsink. Ratchets sold separately.
