Looking at the 600w kit, they are all 100w each and 290PARw/600 making them 48.3% efficient.

Edit: That was the Vero29B, the C version is 48.75% efficient.

To make 56% efficiency there would have to be a 15-20% jump in efficacy and that doesn't happen when you reduce the current by 50%.

Then we should probably let them know they are providing false information. As that's a legal liability. I'll run their numbers once I get the 3500 90cri spectrum... If they would provide it it would be easy to show some accurate information.

Bridgelux? Maybe, 192 lm/w is crazy efficient (59% using LER of 325), and I wouldn't expect that from a chip that mimics CLU048-1825 gen 5 in every way unless it were being run at 15-20 watts.

Fuck lumen measurements, they should be putting out PPF numbers first.

Agreed, I wish they would go by PPF, the advanced calculator is the best way to go with that IMO. 15-20 W would make more sense to me as well, but that calculator will give you as close to real world results as you can get.

Just too costly, from what I saw on eBay at least, like minimum around $7 per watt. Interesting article though. Nice find and thanks for posting about it. If they ever become cheap as LEDs it would be practical.

There was another article i've read a while back about the use of 660nm red laser light at very short intervals in order to assist duckweed growth in contaminated water, i recall it being very effective, gotta dig that research up again..
