Full-spectrum LED grow light delivers 2170 μmol/s, 2.8 μmol/J, and premium diodes for efficient growth across a 5 x 5 area.

The SolarXtreme 820 delivers full-spectrum lighting across a 5 x 5 grow area, pushing 2170 μmol/s of PPF with a PPE of 2.8 μmol/J. That means more usable light for your plants without the wasted heat you get from old HID fixtures. Built with premium LUMILEDS diodes and a dimmable controller, this grow light gives you the ability to fine-tune intensity and simulate natural sunrise and sunset for healthier, less-stressed plants.

Is the SolarXtreme 820 energy-efficient?

The SolarXtreme 820 runs at 2.8 μmol/J, far beyond older HPS fixtures at ~1.3 μmol/J and even premium double-ended HPS at 1.8–2.1 μmol/J. Modern LEDs in this range deliver more light per watt, giving you stronger yields while cutting electricity and cooling costs. For growers looking to scale efficiently, this LED grow light outshines traditional lighting at every level.

FAQs

How many watts do I need for my grow space?

The wattage depends on the size of your grow tent or room. A general guideline is 30-50 watts per square foot for high-light plants like cannabis. For example, a 2x2 ft area may need 100-200W, while a 4x4 ft area may require 400-600W for optimal coverage.

What is the difference between full-spectrum and red/blue LED grow lights?

Full-spectrum LED lights mimic natural sunlight, providing a balanced mix of blue (for vegetative growth) and red (for flowering and fruiting) light. Red/blue LED lights focus on specific wavelengths but may not support plants as effectively as full-spectrum lights.

Does California LightWorks offer energy rebates for LED grow lights?

Yes! California LightWorks facilitates a rebate program that helps growers switch from outdated HPS or HID lights to energy-efficient LED grow lights at little to no cost. Approved applicants can receive 100% free LED lighting through the program.

How does switching to California LightWorks LED grow lights help save electricity costs?
