Hey all, I'm pretty new here so forgive me if this is the wrong thread. I have a 48" Reefbrite Lumilite LED actinic light on my 55 gal system and I'm wondering what are the PAR values that this light can put out. I have another cheap marine LED light that I use as supplementary light. I'd like to know so that I can see if it would be enough light to keep a BTA. Tank dimensions are 48"x12"x21" (LxWxH). Tank has been running for about 7 months. Thanks!
