...has anyone experimented/got values for the cheaper Beamworks LED? I think they are made by odyessa? They have an enticing price tag, but cannot find info on their par/spread.
I looked around for more info on these too. I did not find any PAR data, but based on what I did find (I can't remember if it was lumen or lux values), they're somewhere between Marineland single and double bright fixtures. I think they were quite a bit closer to the single version... not much to hope for if you're growing plants.
In other news, I'll be deploying Finnex Ray 2 units over my 46g bow & 20T right after Christmas!
