Bright 720w LED Grow Light - Full-Spectrum Power for Serious Yields
Best for: growers wanting a full-spectrum LED with genuine 720W draw for mid-to-large flowering spaces, without paying premium-brand pricing.
Our thoughts
The numbers on this one actually hold up - 720W true draw and a PPF output over 1900 μmol/s isn't marketing fluff, it's a genuinely capable light at a price well below what the big-name quantum board brands charge for similar output. It won't quite match the absolute top-tier efficacy figures, but for the money it's a serious light.
The Bright 720W LED Grow Light delivers a true 720W draw, powered by dual built-in 360W drivers, with a PPF output of 1944 μmol/s. Its full-spectrum output blends 3000K, 5000K and 660nm chips to cover the full growth cycle from veg through to flower, with an efficacy of 2.7 μmol/J and efficiency of 155 lumens per watt or higher. The fixture folds flat for quick setup and compact storage, runs passively cooled with no fans or moving parts to fail, and includes built-in dimming in 10% increments straight out of the box.
How it compares
It sits in the budget-to-mid-range bracket of quantum-board-style LED grow lights, below premium Samsung LM301-chip lights on efficacy but well below them on price.
- Versus premium brands like Spider Farmer or Mars Hydro's higher-tier ranges, the Bright 720W's 2.7 μmol/J efficacy is a step below the best premium boards (typically closer to 2.9-3.1 μmol/J), but it costs considerably less for a comparable true wattage.
- Versus Growers Choice and similar mid-market LED brands, Bright's foldable design and passive cooling are common features at this price point, making it a fair like-for-like comparison on build.
- Versus older-style HPS/CDM setups of similar output, this LED runs cooler, uses less power for comparable light levels, and needs no separate ballast or reflector.
You're trading a little efficacy against the very best premium boards for a meaningfully lower price - a fair trade for most growers not chasing the absolute maximum per-watt output.
Usage guidance
Getting hanging height and dimming right makes the biggest difference to how this light performs.
Tent size
At 720W true draw, this is typically suited to a 1.2m x 1.2m tent for intense flowering coverage, or up to around 1.5m x 1.5m for less demanding stages like veg.
Hanging height
Start higher during veg and lower the light as the canopy fills in, watching leaves for signs of light stress and adjusting height or dimmer setting accordingly.
Dimming
Use the built-in 10% dimming increments to ease young plants in gently and ramp up to full power once the canopy has established.
Setup and storage
The foldable design means it packs down flat when not in use, making it easy to store between grows or move between tents.

Who this is for
- Growers wanting serious light output for mid-to-large flowering spaces on a sensible budget
- Anyone upgrading from HPS/CDM who wants lower running heat and power draw
- Growers who value silent, fan-free operation over squeezing out the last few percent of efficacy
- Budget-conscious growers who still want genuine, verifiable specs rather than inflated wattage claims
Best suited to growers running a 1.2m x 1.2m to 1.5m x 1.5m tent who want strong yields without premium-brand pricing.
Our take
This is a light that backs up its numbers - true 720W draw, real PPF figures, and a sensible efficacy rating rather than inflated marketing wattage. It won't out-perform the very top premium boards, but it doesn't try to charge like one either.
If you want genuine power and full-spectrum coverage without premium pricing, this is worth serious consideration. Does exactly what it should, day in, day out.
