8 Best 5×5 Grow Lights of 2026
Eight LED grow lights for 5x5 tents compared, from the Spider Farmer G8600 and Mars Hydro FC-6500 to the AC Infinity IONFRAME EVO8, with output, weight, and heat notes.
A 5×5 tent is the largest common home size, about 25 square feet of growing space. Lights for it are big, heavy fixtures, usually 640 to 850 watts of foldable or fixed bars, and they need a sturdy tent frame and good ventilation.
This guide compares eight 5×5 lights. Fewer qualified than for smaller tents, because many 5×5 fixtures are new listings with few ratings. For 4×4 tents see 4×4 grow lights.
Safety note: grow tent lights draw from about 65 to 850 watts. Hang them from hangers rated for the fixture’s weight, plug them into a grounded outlet (GFCI-protected in a humid tent), keep drivers and cords off wet floors, and follow the maker’s hanging height. Many of these lights include far-red or infrared (730nm) diodes and a few include UV (395 to 405nm); do not look into them at close range. We describe what each maker lists; we do not promise growth or harvest results.

How to Choose a 5×5 Grow Light
Frame Strength
The 5×5 lights here that list a weight run from about 30 to 38 lb. Check your tent’s load rating and use the frame’s crossbars.
Heat
700 to 850 watts heats a tent fast. Size the exhaust fan for the tent and the light.
Coverage Claims
Some lights list 5×5 for flowering and larger for veg; others list 5×5 as their maximum. Compare the flowering figure.
How We Evaluate 5×5 Grow Lights
We did not grow plants under these lights. We compared manufacturer specifications and Amazon listing details, and ranked products by the WikiHomeLED Score, which adjusts the Amazon star rating for the number of ratings (ratings checked November 2, 2026). To qualify, a product had to be an LED grow light sold for 5×5 ft tents or rated for 5×5 coverage, with at least 20 ratings and a rating of 4.1 stars or higher. PPF, PPFD, efficacy (µmol/J), and coverage figures are as published by each seller and are not our measurements. Sellers often list a larger vegetative coverage and a smaller flowering coverage; we quote both where given. Several listings make yield claims; we do not repeat them. Mars Hydro TS, Spider Farmer SF, VIVOSUN LumaLight, VIPARSPECTRA P, and AC Infinity IONBOARD ratings are pooled across every size on one Amazon listing family, so the same rating can appear for different sizes. The full method is on our How We Review page. Brands are capped at two entries. Only eight lights met the threshold.
Frequently Asked Questions
How many watts for a 5×5 grow tent?
About 640 to 850 watts of real LED power is typical for a fully planted 5×5.
Can two 4×4 lights cover a 5×5?
Two smaller lights can, but one fixture sized for 5×5 is simpler to hang and control.
Is a 5×5 tent too big for a home?
It needs about 25 square feet of floor plus clearance, and more ventilation than smaller tents.
Do 5×5 lights need 240V?
Check each listing’s input voltage; AGLEX, for example, lists 110 to 277V. Also check your circuit capacity before running several large lights.
Final Verdict
Spider Farmer’s G8600 is our 5×5 pick for its listed output, built-in app control, and 5-year warranty. Mars Hydro’s FC-6500 lists the best efficacy and folds for setup, and AC Infinity’s IONFRAME EVO8 has scheduling built in. KOSCHEAL’s K640 is the lower-cost option with a thin rating history.
