California LightWorks has established itself as a leading producer of LED grow lights in both the horticulture and cannabis growing industries. The company’s reputation for high-quality grow lights has been steadily growing. Among their products, the SolarSytem 1100 stands out as one of the best.

The SolarSystem 1100 is recognized as one of the most powerful and impressive lights in the LightWorks range. It has garnered a stellar reputation for its effectiveness and quality. This review aims to provide detailed insights and information about the SolarSystem 1100.

About the SolarSystem 1100

The SolarSystem 1100 Series

Designed for commercial-quality grows, the SolarSystem 1100 series offers a variety of lights, including low power options suitable for different growth stages, propagation, all-season, flowering phases, and coverage of small areas.


LightWorks’ SolarSystem 1100 operates at a maximum of 800 watts. However, it compares to a 1000 watt High-Pressure Sodium (HPS) light, distinguishing it from standard LED lights. Growers report that this system’s yields match or even exceed those from HPS lights.

Light Spectrum

The system delivers a full spectrum of light, blending red, blue, and white diodes. This design lets growers tailor the light spectrum to specific needs, adjusting the mix of red, blue, and white light as required. Growers highly appreciate this feature for its straightforward use and effectiveness in promoting healthier, more abundant yields.


California LightWorks openly communicates the SolarSystem 1100’s coverage capabilities. It efficiently covers a 4 x 4 feet area, extending up to 5 x 5 feet in reflective environments like grow tents where walls reflect the light.


The SolarSystem 1100 comes equipped with high-quality, bright 5-watt Osram diodes, boasting a 50,000-hour lifespan. These diodes are designed to produce brighter light at the same power consumption as dimmer alternatives. The system also features efficient heat sinks and ceramic packaging, enhancing heat dispersion and extending diode life.

Heat Emission

The SolarSystem 1100 effectively controls heat emission even with its high-intensity output. In smaller or enclosed spaces, increased ventilation might be needed in warm climates. Although it needs minimal cooling, extra heating may be required in cooler environments.


The system’s spectrum can be controlled with an optional separate controller, enhancing convenience and customizability. The SolarSystem 1100 is easy to set up and compatible with a range of voltages and amperages, and operates efficiently within a broad temperature range.

Size and Dimensions

The unit measures approximately 18″ x 18″ x 4″, with the possibility to chain units for expanded coverage. Optional T-5 UVB fixtures alter the dimensions to 23” x 23” x 4”. The unit’s fans are located on the top, indicating the absence of passive cooling.
