Who This Is For
- You are adding supplemental UVB because you want to push resin production beyond what standard LEDs can achieve.
- You are moving away from HPS because your cooling costs are eating your margins and you need a more efficient setup.
What We Found
- We always suggest the optional controller because the light is far less versatile without that granular spectrum tuning.
- The ability to toggle the UVB bars separately is a huge safety plus for when you need to be in the room with the lights.
- Mounting the UVB units with the included brackets keeps the footprint compact and does not block any cooling fans.
What Users Say
- Commercial teams report significant drops in cooling costs after swapping their hot 600W HPS units for these LEDs.
- Users who added these to their bloom cycle say the extra UVB creates a noticeable difference in final resin density.
- Facility managers mention that syncing these lights via the digital controller saves hours of manual timer adjustments.
California Lightworks SolarSystem 550 UVB Full Spectrum LED Grow Light
Looking for a grow light that truly mimics the sun's power? The California Lightworks SolarSystem 550 UVB is a commercial-grade solution designed to bridge the gap between indoor cultivation and natural sunlight. By combining high-efficiency LEDs with supplemental UVB, this system drives increased resin production and potency that standard LED setups simply can't match.
This commercial indoor LED lighting system is perfect for a single light in a tent or several hundred lights in a large commercial operation. Overcoming the limitations of high-intensity discharge (HID) systems, the SolarSystem 550 offers programmable spectrum control over multiple wavelengths. It operates with exceptional efficiency, drawing only 400W to replace a traditional 600W HPS lamp. For maximum precision, pair it with the California Lightworks SolarSystem Controller to unlock fully programmable spectrum control across all stages of growth.
