GLL4U Series of ActiveLED® Linear Grow Light fixtures, from 288W up to 640 Watt


  • GLL4 Series of ActiveLED® Linear Grow Lighting, up to 680 Watt fixtures for any indoor fully artificial or extended day lighting application - see table for details

  • Lumen Lifetime of 90,000 hours (90% Luminous Flux)

  • Approximate PAR output equivalence - see table for details

  • Easy replacement for conventional Fluorescent and Metal Halide High Bay light fittings

  • ActiveLED® - Environmentally Safe Lighting:
    • Zero mercury content
    • Eliminates disposal of
    hazardous materials
    • Made in USA - local support

  • LG4U Series fixtures include support for the ActiveLED Digital Management to allow on/off and dimming profiles to be enforced.
    Optional ActiveLED controls for additional energy savings:
    • Daylight Sensor
    • Digital Rotary Dimmer
    • LightSpace Management
    • Battery Backup for
    emergency lighting

  • About half the height of traditional HID fixtures minimizes the required vertical installation space

    Less than half the weight (22 lbs) reduces the cost of the supporting structure.

  • Choice in all models of CCT color temperatures - 4000K or 5000K.

    LUM-INTENSETM by ActiveLED® is a new LED luminaire lighting technology that provides more light (more lumens per Watt) - punches an intense amount of light out of a smaller package.



GLL4 Series of ActiveLED® Linear Grow Light fixtures, from 288W up to 640 Watt fixtures for any indoor plant and produce growing environment.

New generation grow lights combine state-of-the-art LED, electronic and mechanical design, choice of 288, 420W or 640 Watt models for indoor grow applications

The ActiveLED® GLL4 Series Linear Grow Lighting consumes at least 50-85 percent less energy than conventional lighting and additional energy savings can be achieved with the reduced need for air-conditioning.

With its patented design and superior LED elements, the ActiveLED GLL4 Linear Grow Light is a reliable light source with a 90,000-hour lumen life, making it a maintenance-free solution for applications where changing bulbs and ballasts can be hazardous and expensive.

PAR Expectations (approximations may change with environment)

Fixture Type 6 fixtures in 5' grid single fixtures in 10' x 10'
cubical with white walls
288W ~750 PAR ~500 PAR
300W ~780 PAR ~520 PAR
420W ~1100 PAR ~729 PAR
600W ~1500 PAR ~1050 PAR
680W ~1750 PAR ~1180 PAR
Note: GLL4U grow light PAR is measured 24" below light emitters in 5' x 5' grid, or at 18" for single light with a CCT of 4000K.

Significant savings from not having to maintain and renew ballasts and HID lamps, as well as significantly reduced heat generation and energy use justify the initial outlay.
