    the uv color of an led is not a true uv. its just a purple. if they were than they would kill things. OBD uses them as a substitute for red. its in the red family to help the corals. but it helps to not let algae grow as easy.

    Ben the ones he linked to are in the UV range.

    Hmm not sure TaT, I know the units we run are 40 watts each (as in traditional UV bulb and ballast). It does say they got a contract for water purification, might be worth seeing how many and how much.

    This would be the proper wavelength, right around UVC range, does anyone know what UVC would do to a piece of acrylic long term.

    Well after doing a little research, found out that just one of the LEDs cost almost 300 dollars.

    Such as with any new super high efficiency lighting, though the first generations are pricey, but they pay for themselves very quickly in energy and bulb replacement costs.

    I agree with the cost thing "OVER TIME" but MAN those REEF capable LEDs are no joke on prices!!! And for me I couldn't trust them on my reef??? Only because I never had LEDs other then they make GREAT Shimmer for moonlights!!!

    Very similar to Halides except a lot more controllable and whereas most of the energy in Halides goes to heat, with LEDs, the vast majority goes to light and to wavelengths desirable for coral.

    Maybe when the prices go a little down I may try those types of light but as for now just way too expensive for my Blood!! Do you run LEDs on your system FISHfishy??? I would luv ta see if you do and see pics of the Growth and health of your corals!!!Sorry I'm stuck in the OLD school type lights!!!

    I swapped out my combo Halide/CF lighting to LEDs about a month ago and love them and the lack of chiller need. Have posted a video recently. will look for it.

    What is a good combination of LED bulb colours for both growth and appearance (how many of each colour, as a percentage)?
