    The SolarSystem features the latest generation high output UVB T5 fluorescent bulbs as well as the most versatile control system on the market. This system is perfect for a single light in a tent or several hundred lights in a large commercial operation. 

    This light is best used as a supplemental light along with other primary grow lights.


    • Supplemental UVB-24 watt T5 Fluorescent.
    • Improves resin development and potency.
    • Used during the last few weeks of flowering.
    • Piggyback design offers up to 10 unit installations from a single outlet.
    • Covers 4' x 4' at 3' above the canopy.
    • UVB bulb is included.
    • Measures 23" x 4" x 2" 



    UVB is measured in µW/cm2 or microwatts per centimeter squared. Over a 4' x 4' area with the SS-UVB hung at 3' you're going to get about 90 µW/cm2 in the center, 35-50 µW/cm2 on the outside edges, and 20 µW/cm2 in the corners. This distance allows for longer exposure times (depending on plant genetics) with less chance of negative effects on your plants. 3 ft is also the ideal hanging height for best possible uniformity. The graphic below shows UVB measurements over a 4' x 4' area with the SS-UVB hung at 3'.



    Hanging Height

    The SS-UVB covers a 4' x 4' area at 3' above the canopy. It is recommended that you mount the SS-UVB at this height. Different plants with unique genetics will respond differently to the intense UVB light that this fixture puts out. When growing cannabis, sativa dominant strains typically have a higher tolerance to intense UVB than strains that are indica dominant. If you notice leaves on your plants start to turn brown around the edges, increase the distance between the UVB and your plant or decrease the exposure time per day. If you don't notice any unwanted results, you may gradually move the light closer to your plants or increase exposure time at your discretion.




    The SS-UVB is designed to be used during the last 2-3 weeks before harvest, when it can make a noticeable impact on plants. It is suggested to run your SS-UVB for 2-6 hours per day at 36" above the plant. If you're unable to mount the light at 36" above your plants, decrease the amount of exposure time. Do not power your SS-UVB on during your dark period as this can cause unwanted effects. Always monitor your plants to make sure you are getting the desired response, while making any necessary adjustments in height and/or on time to increase or decrease UVB exposure as desired. Growers typically see a noticeable difference in the amount of trichomes within the first two days after running the SS-UVB for just a few hours per day. Many growers also notice leaves changing color in response to UVB exposure.

    I love this light

    I want a room full of them they are awesome!

    Joseph M.
    Difference was almost instant!

    Not only did my trichomes grow in size and numbers, but they made my harvest come early buy 5 days with amazing Amber/cloudy ratio. I only use them in the first two hours of light, in the last 20 days of flower. Thanks!

    Jeremy A.
    If you grow indo u need this light!

    It's been proven high u.v.b levels increase trichome/resin production and in th north we can use the sun for only 4 months a year so especially northern growers NEED this light. Southern California....not so much. Plus you also need to buy this because it wasn't made by communist savages, made in the USA, when was the last time you saw that?

    As always California light works products are the rolls Royce of their made right here in MERICA

    Just a Little Does Wonders!

    Received order on time, everything was securely packaged. The service from LED is superb and the quickness from the time I ordered to the time I received the order was top-notch! California Lightworks SolarSystem UVB 24W, just a little does wonders, improves overall everything, from yield to oils. But don't over do it, or it will have the opposite effect. I only use in the later stages of development (which could be different from someone else's needs) right before harvest, so roughly around 3 weeks of use, starting out at around 15 minutes, then rounding off at the later stages of about 45mins per day. The light itself is very light, making it easy to hang, and small enough to fit in-between the main lights, and seems sturdy.
