FloraFlex 700W LED Grow Light Review: 2024 Test + Grow Update

Short answer: the FloraFlex 700W fixture I tested in 2024 delivered a lot of light for its launch price. At 25 inches and full power, I recorded about 1,000 µmol/m²/s in the center and roughly 500–600 at the corners. After a complete grow, my biggest complaint was heat: this fixture raised my test tent about 18°F under those conditions.

What the meter actually recorded

The wall draw stabilized around 208.9 watts at 30%, 348.4 watts at 50%, 497.4 watts at 70% and 740.9 watts at 100%. That makes the dimmer labels useful reference points, but they are not exact wattage percentages.

At full power and about 25 inches from the sensor plane, the center reached roughly 1,000 µmol/m²/s while the corners were closer to 500–600. The light had enough output for a 4×4-foot flower canopy in my test, but the spread was not uniform. One center number should never be treated as the whole map.

The full-grow update: heat changed my score

My original video was an excellent first impression. The complete grow exposed the part a five-minute bench test could not: in my stable room and tent, this fixture increased tent temperature about 18°F, even after I moved the driver outside. Comparable lights in that space had typically raised it around 10–12°F.

That is a single-room observation, not a universal temperature guarantee. Room size, exhaust rate, ambient temperature, driver location and total wall draw all matter. Still, it was repeatable enough in my setup to lower the final recommendation. The same extra heat could help a cold winter room and become a major cooling penalty in summer.

Use targets—not my old week-by-week distances

The original post listed one fixed dimmer-and-height schedule. Treat those numbers as a record of my 2024 setup, not a universal recipe. Cultivar, canopy shape, CO₂, temperature, sensor position and fixture generation all change the useful setting.

The inverse-square rule in the video is a useful warning that intensity can rise quickly as a light gets closer, but an LED bar fixture is not a perfect point source. Use a real canopy map. The updated LED selection guide, Photone-versus-Apogee test and equipment-generation guide explain the current method.

Off-peak power can help—but check your own rate

The savings in that video applied to a specific time-of-use plan. The U.S. Department of Energy explains that time-variable plans can include peak, off-peak and shoulder periods that vary by utility and season. Check your own provider’s current tariff before changing a light schedule. Off-peak pricing can lower the bill, but it does not reduce wattage, heat or the need for ventilation. See the DOE’s time-variable pricing overview.

Frequently asked questions

How much power did the tested FloraFlex 700W draw?

I measured about 208.9, 348.4, 497.4 and 740.9 watts at the four marked dimmer settings.

How even was the PPFD?

At about 25 inches and full power, the center was near 1,000 µmol/m²/s while the corners were roughly 500–600 in my setup.

Why did the final review score change?

A complete grow revealed an approximately 18°F tent-temperature increase under my conditions, which was higher than comparable fixtures in the same space.

Should every grower run lights at night?

No. First verify the utility’s current time-of-use plan, the room’s nighttime temperature and whether the schedule works safely for the grow.
