I want to try a saber 100 w as a T5 replacement but at $225 for one thats crazy talk. If i convert my 5 fluorescent to led its $125 for bulbs. And there 41 watts each so 164 watts for 4. Power consumption is wayyy down. But i cant find the boards they use to make the saber light anywhere. You can by cob light in boards but only blue, red, green. I have found a driver $14 and the light for $119 so thats better that horticulture lighting groups prices. And the driver only pulls 60 watts. So i like the 60 watts vs. 164 watts. So i think im gonna try one out for my vegging nursery tents.
