What would you use that for? I don't see it being enough power by itself.

LEDs are much more efficient converters of electrical energy to light energy than fluorescent or MH, which is why they are the future of lighting.
I'm not sure what the ratio of output is, but I'm guessing its in the magnitude of 10:1 or so. I'm hoping someone here can provide more exact numbers.

From my catalog.
GE 100w A19 frosted bulb =1680 lumen's
Your going to need a WHOLE LOT MORE LEDS, just to equal that.
They are more efficient at producing light, if you look at the 100 watt bulb, it's delivering around 16.8 lumen's per watt. The LED is doing over 3 times that.
BTW the 100 watt incandescent might be enough power for a low lit, shallow tank. But not likely enough for much more than that. Also, this is not a full spectrum bulb. It's very probable that a FS would produce less light per watt. Maybe we have some old timers who will chime in on incandescent use with reefs.
Additionally part of the effeiciency is in bulb life with miminal par loss. !0yrs. is a incredible life for a bulb.

I emailed the company, and they said that normal fluorscents produce 30 lumens of light per watt. The LEDs produce 60 - 80 lumens per watt. So its an improvement of 2 - 3x over fluorescents, and given your 17 lumens/watt for the good ol' incandescent, that's a 4 - 5x improvement.
Not everything I was expecting, but not bad at all.

BUT>>>> Lumens arent what your after for photosynthesis. I cant tell you what PAR the incandexcent might have........Also, the visible light output put any specific lamop is varialbe with different circumstances. The light you have is going to do you no god as is for a reef.

The powerbrite LED system is causing a lot of confusion in the hobby from what I've seen due to clever marketing. The manufacturer doesn't exactly go out of their way to make it clear, but you'll often find these things marketed with words like "Subtle" and "Supplementary" in their descriptions.
They are not suitable as primary lighting. It may create a bit of a glow in the tank, but will by no means provide for a well lit tank, for reef or otherwise.

I was just planning to use this for a 6g FW tank until ReefforBrains MacGyver-ed a bulb for me
Now, I'm really not too sure what I'm going to do with it.

Flourscents make more then 40 lumen per watt. Try 85-100 lumen.
