Compact 42W LED light with 85–264V range, deep penetration, and 30,000-hour lifespan. Ideal for small grow rooms or HPS support lighting.

This 42W low-profile LED grow light is specifically designed for growers with limited height and small extraction systems. It’s ideal for micro-grows, propagation shelves, or as an HPS add-on light to increase canopy penetration without increasing heat. Unlike older technologies like T8 or TCL, this fixture offers superior spectral quality and enhanced light penetration in a compact, energy-efficient design.

Rated for 30,000 hours of use with no yield drop over time, this light outlasts and outperforms fluorescent options while drawing minimal power. With a voltage range of 85–264V, it integrates easily into any setup, delivering long-term reliability in both hobby and commercial spaces.

Is this 42W LED grow light energy-efficient?

Absolutely. With just 42 watts of power draw and efficient spectral output, this fixture delivers high-quality plant light without excessive power consumption. It’s ideal for reducing heat loads in compact spaces or supplementing larger lights without raising HVAC costs.

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.
