Thinking about LED upgrade

[brian313313]

I need more light in my aquarium. Currently, I have two 36" T5 HO bulbs. I can get two more of them but I was thinking about maybe getting an LED fixture. I can't figure out how many lumens any of them have though. I've read that they average about 100 lumens/watt so either lumens or watts could help me. I want about 15,000 lumens total which is about double my current (estimated) output. Mostly, I need to figure out the price. The cheap ones have the lumens and they're way too low...just for supplemental lighting. Does anyone know how to figure this out? Any recommendations on 36" LED fixtures?

Thanks.

I don't think that measuring watts or lumens is the best way to measure the light output of leds. There was a post a few days ago with a good discussion on this topic. I think the best strategy is to Google search for led lights & size of your tank. They to find posts that include PAR readings. Then pick one to copy/modify.
