Best LED Grow Lights for 5x5 Grow Tents
A 5x5 is 25 square feet — 56% more area than a 4x4 — and it's where single-panel fixtures stop working. You want 650–1000W of actual draw spread across a bar-style frame, because corner uniformity is the whole problem at this size. Every fixture below is rated for a full 5x5 footprint and dimmable. If you're running CO2, look at the 900W+ options; without it, 650–750W is the efficient choice.
How to choose a 5x5 light
- Bar fixtures only. A single panel over 25 ft² leaves the corners 40%+ dimmer than center.
- 650–1000W actual draw for flower. 750W at 2.7 µmol/J puts you near 800 PPFD across the footprint.
- Check the PPFD map at 5x5, not 4x4. Manufacturers routinely publish maps at the smaller footprint because the numbers look better.
- Driver placement. Remote drivers move heat outside the tent — worth it at this wattage.
- 208–277V options exist at this tier and cut your amp draw meaningfully if you have the circuit.
What to skip
- Two 4x4 panels side by side. Cheaper up front, worse uniformity, twice the hanging hardware.
- 1000W+ fixtures without CO2. Past ~900 PPFD, extra light is wasted money.
FAQ
How many watts for a 5x5 tent?
650–1000W actual draw. 750W is the efficient sweet spot without CO2.
Will a 4x4 light work in a 5x5?
It will grow plants in the center 16 ft² and waste the rest. Size to the footprint.
Do I need 240V?
No, but at 750W+ a 240V fixture halves the amp draw and lets you run more fixtures per circuit.
