LED Grow LightSWITCHABLE, MULTI-SPECTRUM LED
FEATURES & SPECIFICATIONSINTENDED USE — Allows for indoor gardening year-round. This luminaire is multi-spectrum with switchable color options for a variety of growing needs depending on plant species, season of growth, and user preference.
Includes: 5' plug-in power cord, color-coded toggle switches, on/off rocker switch, swivel power ports with covers, chains for suspension mounting, mounting hardware, and connector for linking multiple fixtures in side-to-side or end-to-end configurations.
CONSTRUCTION — Compact design formed from cold-rolled steel with durable injection-molded end caps. Features a matte white reflector and clear polycarbonate lens.
OPTICS — GRWL is switchable between single color or combinations of red, blue, and full (white) spectrums in the PAR range of 400 to 700 nanometers to promote photosynthesis in plants.
Red LEDs emit 655-670nm light useful for seed germination, root growth, and flowering.
Blue LEDs emit 440-455nm light useful for vegetative growth.
Full spectrum (White) LEDs provide task and display lighting with 80 CRI at 4000 K.
ELECTRICAL — Fixture operates at 120 volts, 60 Hz. Standard input = 29 watts. Actual wattage may differ by +/- 5% when operating at 120V +/- 10%. Operating temperature: 32°F (0°C) to 104°F (40°C).
INSTALLATION — Flush or suspension mount. Plug in or direct wire. Linkable up to 354 watts maximum (approx. 10- 24" fixtures). Adjustable chain set and linking connector included (linking connector cord sold separately). Luminaire should be installed in applications where ambient temperatures do not exceed 104°F (40°C). Recommended mounting height: 6" - 18" centered above grow area.
LISTINGS — UL Certified to US and Canadian standards and listed suitable for damp locations.
WARRANTY — 3-year limited warranty.
