Yap. Technically, LED produce around 10% less heat than a typical fluorescent bulb. Its just that, fluros have a heat-light ratio of 95%-5% while LEDs have 85%-15%. Fluros cannot be fitted with heatsinks :P and hence LEDs get the big advantage along with being DC out-of-the-box.

I didn't want to throw any numbers out as the % I heard could be wrong. I heard incandescent was 90%-10% heat to light but I don't remember where I heard that. In any case artificial lighting is very inefficient by nature.

in an effort to cut heating costs I have deployed 3 x 250 watt metal halides over my tank. This approach seems to work well as my 3 x 300 watt heaters only seem to kick in for a few hours during the late night hours.

That's fine in the winter but how high does your temp get in mid summer without a chiller?

In the summertime we turn on the most expensive to run appliance that man has ever created.. Our central AC. Thankfully there's not that much "summer" to worry about in Cowtown

Haha, you have a point there!

And you don't to connect those halides to the computer to get the "sweet spot". Some minutes of savings in computer's power too
