Who This Is For

  • You are upgrading your fixtures because you need a blue-heavy spectrum to push higher quality harvest profiles.
  • You are standardizing your canopy layout because your current lights have hot spots that lead to uneven ripening.

What We Found

  • We tell customers the extra weight is a good sign that the heat sinks are actually dissipating heat correctly.
  • Our testing shows the 3.0 efficiency rating holds up even when running these at full power for 12 hours straight.

What Users Say

  • Operators who added the EL3 controller say the sunset dimming feature stopped the plant shock they saw from timers.
  • Users report that the extra blue light led to a higher quality extraction because of improved oil profiles.
