Updated November 3, 2026
Mars Hydro’s TS series of boards with white reflector hoods is the most-rated tent light family we found, about 20,400 ratings at 4.6 stars pooled across sizes. The brand also sells FC and FC-E bar lights and the SP strip fixture.
This guide compares nine Mars Hydro lights by line. For other brands see Spider Farmer and VIVOSUN.
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 We Evaluate Mars Hydro 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 a Mars Hydro grow light (supplemental and seedling bars excluded), 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. This is a single-brand guide, so the brand cap does not apply. TS series models share one pooled rating.
Frequently Asked Questions
Is Mars Hydro a good grow light brand?
Its TS series has the largest rating base among tent lights we found, about 20,400 ratings at 4.6 stars.
TS or FC series?
TS boards are simpler and cheaper; FC bars list higher efficacy and spread light more evenly in bigger tents.
Do Mars Hydro lights have app control?
The TS3000 and FC lights work with Mars Hydro controllers sold separately; the SP3000 lists WiFi app control.
Which Mars Hydro light for a 2×4?
The TSL2000 or the SP3000, both shaped for long tents.
Final Verdict
For most small and mid tents, a TS board is the Mars Hydro to buy: the TS1000 for 2×2 to small 3×3, the TS600 for the lowest cost, and the TS3000 for 4×4. Choose FC bars when you want published efficacy and even coverage in larger tents.
