My old Ford truck had a 460 CID engine. Yet it was slower than my new pickup despite the fact that they were the same overall size and the new truck had a smaller engine.
Well anybody with a clue will point out that the new truck is newer. Therefore more efficient and simply better. Who cares?
The light you posted only provides 5050 lumen of light despite being 165 watts. That's a paltry 30 lumen per watt. Probably an old light that they couldn't sell 5 years ago.
New Bridgelux LEDs are pushing 100+ lum per watt. Cree are better.
3 WATT LEDS MEANS NOTHING.
Please ignore those who say it does
Lumen per watt is what matters.

Lumen per watt is what DOESN'T matter. Lumen is something made up by humans. Plants and corals couldn't give a crap about lumens. These LED
's are tried and true and a lot of people swear by them. I thought all the nay sayers were gone when they were proven wrong years ago. I think it a thread on reefcentral that was about these chinese LED
's. At the start of the thread, there was only people saying that these LED
's would never grow coral in the long run because they're cheap. Years later and there's almost only good reviews. People have proven that these lights will support coral for years, and have coral THRIVE under them.
Also, new bridgelux leds only put out 100 lumen per watt when they're running at full power. These LEDs only run at 2w or less so they last longer.
