This is the largest of the grow lights by Flexstar, the 1,000W PRO. It is 5ft x 4ft or 1.5m x 1.2m in size and consumes 1,018 watts, a massive fixture by any measure.
Flexstar is a huge global player in the indoor growing market and has been manufacturing grow lights for many years.

The build quality is excellent and very solid too. The hinges are up to the task of securing this big light and the LED driver fixes nicely to the back of the LED bars. The driver has on board dimming from 40% to 100% in 20% increments and ports for daisy chain dimming control.

The LEDs are a mixture of cool and warm white Samsung LM301B and 301H with added Osram 660nm reds. The light output is full spectrum and suitable for growing from seed to harvest.

I tested the fixture in a 6ft x 4ft or 1,8m x 1.2m test area with silver mylar walls. The power consumed was 1,018 watts and the average PAR output across the test area was 1,102 µmols resulting in a system efficiency of 2.34 µmols/watt or usable PPF/watt.

This fixture also comes with a 5 year warranty demonstrating the companies confidence in the quality of their product.
Overall a great fixture I am happy to recommend.
