The SolarStorm 440 is a very powerful LED based grow light. It features 144 high flux bin OSRAM SSL emitters.  The system is designed to cover an area of 3′ x 3′ for Bloom and up to 6′ x 6′ for Veg.

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.


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

Actual Power Draw of the SolarStorm 440:

  • In Veg mode, the unit consumes around 235W
  • In Bloom mode, the unit consumes around 320W

Stunned at the low power draw and efficacy of this lamp. Currently a month in, veg is very strong and consistent. Fans are a bit "computer roomy" loud, but not really an issue. Well made unit, looking forward to seeing the bloom and UVB bulbs do their thing. Runs very cool.

Excellent light

I've used my solarstorm 440's for a month now and they are kicking my 600w HPS to the curb. great growth and way less heat. I'm stoked!
