Two channels, 3000K and 4000K, for a 3500K spectrum.
Ideal for about a 1m x 0.6m area.
Consists of 576 Samsung LEDs:
288 x LM561C S6 3000K LEDs
288 x LM561C S6 4000K LEDs
Two driver options:
XLG-200 (94% efficient, 5 year manufacturer warranty) LRS-200 (89.5% efficient, 3 year manufacturer warranty)
Like most grow-bar style lights, these need to be kept closer to the plants than most lights. The sweet spot is around 20cm.
Samsung LED calculator gives a board level efficacy of 190.5lm/W, so the XLG driver provides 179.1lm/W and the the LRS driver provides 170.5lm/W. These equate to approximately 2.6 and 2.5 uMol/J efficacy.
