    I dont know the source of the one presented here but there is plenty of data sheets out there.

    correction tested at 1000 hrs
    I guess the chart is wrong because I did not see any Bridgelux listed as 85C only Cree and Luxeon? One other thing was on CRI, to explain CRI T5HO's are a perfect example. To our eyes they look bright and make everything look great, but to a meter they don't fair as well, both in foot candles and PAR. That was harsh I should of said they are not as bright as our eyes lead them to be?

    Sorry BBQ I was looking at nano reefers chart. I final looked at yours. Funny thing is I just got off the phone with another lighting rep of another manufacture and his take on LED's. When I asked him what he thought of Cree, his answer for Cree was crap. He says Samsung is where it is at? I guess even on the commercial side there are plenty of arguements? Anyway back to my metal halides, let me know when ya'll get this led thing figured out?

    this is why I love to build them. I built 4 Bridgelux diys for a fraction of a single cree fixture and I covered 8ft side to side.
    CREE is not the best anymore per their own report, it appears it be this Rebel Phillips LED and testing to 200lm/W. I think there like $5.
    The 5watt cree LED seems to beat the performance and that something to look at too. My goal is to save power and pack a punch on reef lighting.

    no comment needed, correction same cost of a single fixture. not a fraction. but it is 8ft side to side.

    it would be nice to put some stronger LEDs on the heatsink
