240W High-Efficacy LED (2.9 umol/J)
Stage: All stages
$259
View cart & checkoutEfficacy is how much usable light a fixture makes per watt it burns. At 2.9 umol/J this board delivers the photon output growers expect from a 400W-class fixture while drawing 240 watts from the wall.
Over a 12-hour flowering day that difference is real money: roughly 1.9 kWh a day instead of 3.5, which is a meaningfully smaller line on your power bill every month for the same harvest.
Dimmable from 0-100% so one fixture handles seedling through late flower, and passively cooled so there is no fan to fail or hum.

Questions about this product
- Is a 240W light really enough?
- For a 3x3 canopy, yes. Yield tracks usable photons delivered, not watts consumed, and a high-efficacy board delivers more photons per watt than older fixtures.
- How much will it add to my power bill?
- Around 1.9 kWh a day at 12 hours on, so roughly $8-9 a month at 15 cents per kWh. Our light coverage calculator works this out for your exact tent and rate.
