I would like to see charts comparing bridgelux vs cree vs luxeon. I am running luxeon leds on my tank.

zach who was the source of the spec sheet? so far the relationship between the system thermal resistance, drive current, and ambient temperature from the individual data sheet from the manufacturer indicate a stronger current for cree over the bridgelux
therefore again it depends on tank size why you would need a stronger LED over the other. The cost of the LED makes a big difference.
you could get a powerful LED setup on a shallow tank and be overkill on the light. Deeper tanks need more light and more current.
correct me if im wrong.
I believe Zach compared his visual findings from his bridgelux to his cree setup. And for him CREE is brighter. There is more current driving the LED.
I have ran Bridgelux LEDs on 2ft deep tanks with success. Placement is important. sps higher than softies.
I went with long heatsinks so I can get coverage on the edges of the tanks and control the light with a different lense.

It essentially boils down to CREE being more efficient than BL. With that said, I've been happy with the performance of my BL setups.

need more info tank specs and fixtures looking at and what is the goal? there is allways a brighter LED.

I can't believe most LEDS are only rated for 25C, now I know why my manufactures use Cree rated at 85C

Explain?.... Im lost.. Lol

hmmm 85x33.8F=2873degrees Fahrenheit. Thats insane temps. Temps on Mercury are 400C and Venus is 800C. I dont know how they can validate those temps.
when would you ever get that hot? Everything around the LED would melt. Im confused. something weird in these stats.
stat needs to be cited
