GLIB300D – 290W Dimmable COB LED Grow Lights

  • The COB LED has a much higher photon density and uniformity comparing to ordinary SMD, and since the substrate is directly attached to the heat sink, heat dissipation is more efficient, therefore able to endure a longer lifetime.
  • Effective footprint is up to 2.5ft x 2.5ft (0.76m x 0.76m) at the hanging height of 30in(76.2cm), with an average PPFD up to about 432 μmol/m2/s.
  • Max actual wattage is 290W, equivalent to a 400W HPS light.
  • 0-100% dimmable, with wireless remote control.
  • Full-spectrum with UV and IR which is significant for high THC content and enhancing Emerson Effect. Custom spectra service is also available.
  • The secondary optical lens optimizes PAR distribution and canopy penetration with 3 light distribution options of 60°, 90°, and 120°.
  • Active cooling with 2 fans per COB LED, fan’s lifetime up to 50,000 hours.
  • All key parts come from well-known international brands, including LED chips from BridgeLux and Epileds, Meanwell drivers, Sunon fans, etc. Light’s lifetime is up to 50,000 hours.

PPFD footprint of 30in(76.2cm) hanging height

*This test is based on the model with light distribution of 90°.

Effective footprint of 2.5ft x 2.5ft (0.76m x 0.76m) at hanging height of 30 inches(76.2 cm) above the canopy, with average PPFD up to about 432 μmol/m2/s.

*Please NOTE: This PPFD chart does NOT consider the overlapping illumination effect from adjacent lights. When the lights are installed next to each other in the order of a grid, every light’s footprint will be at least overlapped by the adjacent 8 lights. The actually average PPFD could be certainly higher in such an installation way. Therefore, when this PPFD chart is used as a reference factor for the actual installation plan, it is necessary to consider the overlapping illumination effect of the adjacent lights.
