This feature allows these grow lights to imitate the UVB emitted by the sun and it is the only grow light to offer such feature in the market today because of its LED diodes. The SolarStorm 440w is ideal for use in a medium-sized or home grown operation.

It’s designed to replace a 600 watt High Pressure Sodium or Metal Halide system. It is also used on light movers to obtain optimal results while covering a larger area. This grow light is great for smaller indoor grows that do not need the power provided by the California Light Works 880w model.

California Light Works Solar Storm 440w


The SolarStorm 440w has a lot of good things in store for growers. It provides a wide light spectrum. Aside from lighting the plants using LED, Light Works also included two fluorescent T8 tubes to provide the plants with everything that they need and produce large harvests.

The SolarStorm 440w can also save you 50% in power consumption compared to other grow lights. This means you can make more money in the long run.

It’s encased in high quality materials. Light Works made sure of that by using high quality ceramic substrates, a sealed electronics section, jewel quality glass optics, and long-lasting aluminum and sheet metal construction.

You might not believe it if you’re told that this led grow light operates at 90% efficiency. No light and money are wasted in the process.

Since this light only measures 15” x 18” x 5”, it can fit within small cabinet grows or your standard grow tent or greenhouse.


The only drawback in using the SolarStorm 440w is its expensive price tag. At $900, small-time growers might hesitate to invest their money on it. However, this grow light will pay for itself over time.
