* High lumen output: Initial lumens: 37,000. 120 lm/w, 570 μmol/s, color temperature: 3,100K
* Long-lasting light: 90% lumen maintenance at 8,000 hours; 85% maintenance at 20,000 hours. Cap base: PGZ18 base
* Richest spectrum flowering bulb in market with a CRI (color rendering index) of 90: A proprietary phosphorous coating on the outside of the arc tube provides the richest spectrum and produces more photosynthetic
* New technology of optimal flowering: The use of UV far-red spectra promotes higher rate of metabolic activity and resin production, optimal for flowering while also can be used for veg growth as well; Active radiation (PAR) per watt than standard HPS/MH bulb
* Low heat generated & enhanced lifespan: 15,000 hours’ lifespan; Great for indoor horticultural or supplemental greenhouse lighting
