The SolarStorm 440 is a very powerful LED based grow light. It features 144 high power 3 watt OSRAM LED emitters for a total nominal power of 440 watts (144 x 3). The SolarStorm 440 also features a unique supplemental UV-B mode which is essential to develop higher potency. The sun naturally contains large amounts of UVB. HID lights do not deliver any significant levels of UVB. No other LED grow light in the market covers the UVB spectrum because LED diodes are narrow band and focus their light in a narrow spectrum. SolarStorm employs unique T8 fluorescent UVB bulbs integrated into the fixture with a separate control. The UVB bulbs are typically turned on during final few weeks or "finishing" phase of the grow cycle to boost the potency of the final harvest. The SolarStorm 440 is designed to replace a 600W HPS or Metal Halide system. It is great for medium size or home grow operations. It can be used on light movers to cover larger areas and get even better results. 


  • A switch to change the spectrum from Veg to Bloom
  • Supplemental built in UV-B bulbs

Actual Power Draw of the SolarStorm 440:

  • Veg mode: unit consumes around 235W
  • Bloom mode: unit consumes around 320W
  • Bloom mode: with UVB T8 bulbs on, around 350W

The NEW California Light Works Solar Storm 440w LED Grow Light is the latest LED technology for indoor grow rooms and greenhouse gardens. The Solar Storm 440w LED Grow Light balances between having high quality LEDs with strong intensity at an inexpensive price relative to other LED grow lights on the market.
