    It is not an easy question to answer. LEDs are a technology with many levels of quality, quantity and efficiency. For the aquarium, you should not consider LEDs that run much less than 2.5-3 watts per led and produce at least 96 lumens per watt. The best end of the technology is more expensive, but is where you make the savings in power costs, as well as get the spectrum you need. Wattage is misleading, as there is no specific wattage for any given led. They are run under constant current at a specific voltage-amp ratio to get a desired wattage (which is efficient). Various leds are designed for specific scenarios.

    LEDs are different than previous lighting systems in that they are capable of producing very specific wavelenths of the spectrum. It allows aquariums to be lit with specific mixes of the visible (and theoretically non-visible) parts of the spectrum.

    If you want to get an idea of what SA is doing with leds, go to The Serious Reefers sub-forum, where you will find plenty of infos and pics.
