The hortibloom Mega Optic 800W is a commercial grade LED grow light for a 4ft x 4ft up to 5ft x 5ft grow area. It has optical lenses on the LED bars to direct the light down onto the plant canopy from a height. The lenses will prevent light overspill and direct more light onto the plant canopy when there are no reflective walls.

The LED driver is a Powerland power supply and has on board dimming and RJ12 connections for remote dimmer control.

The LEDs are white Samsung LM281B Pro LEDs with additional Osram 450nm blue, 630nm red, 660nm red and 730 nm Far reds. The overall spectrum is suitable for growing from seed to harvest.

I hung the fixture at the recommended 12" or 30cm height in a 4ft x 4ft or 1.2m x 1.2m test area. I took 64 ePAR measurements and recorded an average PAR intensity of 1,481 µmols/m²/second. A very high PAR intensity requiring supplemental CO2 to utilise the light.

I then hung the fixture at the recommended 18" or 45cm height in a 5ft x 5ft or 1.5m x 1.5m test area. I took 100 ePAR measurements and recorded an average PAR intensity of 940 µmols/m²/second. With a consumed power of 806 watts the system efficiency of this fixture is 2.62 usable PPF per watt. An excellent result.
