Best LED Grow Lights 2025 | 5×5 Coverage Area

Updated: Nov 1, 2025

LED grow lights designed for large grow spaces can be a serious investment. Unfortunately, many lights on the market today are inefficient, fail to deliver true 5′×5′ coverage, or are severely overpriced. If you’re spending close to—or more than—$1,000 on a fixture, it’s critical that it delivers on performance, longevity, and even light distribution.

I’ve been researching horticulture lighting and growing with LED technology for over 10 years. One of the most frequent questions I get is: What are the best LED grow lights for a 5×5 space?

In this article, I’ll share my top picks for the Best LED Grow Lights in 2025 for a 5′×5′ flowering footprint. These lights are suitable for full-cycle cultivation, from seedlings through harvest. Only complete, ready-to-use fixtures are included—no DIY kits or lights that require complex assembly.

To make the list, each light was evaluated based on PAR output, efficacy, spectrum, light spread, diodes, drivers, and warranty. I’ve excluded any models priced above $1,000, as I believe better value can be found below that threshold.

Prices change often, so click the product links for current deals. Want to understand PAR, efficacy, or coverage better? Check out my Complete Buyer’s Guide to LED Grow Lights.
