    Hi guys

    Found a really good LED floodlight at Rabtron.
    They have a 10 watt and 30 watt in stock.
    Look like SMD type of LED, 2500lms for the 30 watt, 120 degree, big heatsink, watertight, 6000K to 7000K.
    Unfortunately its not cree, chinese built unit.

    Here is the link to look at

    Very cool Arno you sure are the trend setter in LED lighting, well done. Are the bulbs replaceable and can they supply 10K kelvin output ?

    Hello Trev

    So far im just playing around with the lights, fish think they at a disco!
    Regarding bulb replacement, I think it is manageable but you will have to know how to do it. Since the unit is built in such a manner you dont have to open the unit unless needed. To me the LEDs look like SMD (Surface Mounted Diodes) compacted together to make it one big LED. And as I remember from research, SMD are not really sufficient LEDs, but then technology has improved. Kicking out 2500lms is quite impressive for such an SMD LED.

    For instance if you want to replace the built in LED with a cree or luxim 10000 Kelvin led. To do that, for example, you will have to get Cree which are similar in size to fit together in the whole unit. I think it can be done.

    Im not sure if they can supply with a 10000 Kelvin, but maybe in the future they will. The 6500 Kelvin form this LED is stated to be cool white, but when placed over the tank, the water look more "warmer". Many factors play a roll in light color when the light rays penetrate the water, like ambient lighting, how clear is the water, color of live rocks, etc.

    So the yellow effect can easily be balanced out by adding a few blue/royal blue LEDs or T5s.

    I have not had a chance to completely open the unit, just the driver area to have a look in there. Otherwise the whole unit with big heatsink look strong and has a wide spray area and a water sealed cover glass.

    Arno

    Also SMD LED type. More even spread than over a "spot area".
    Those type of LEDs are difficult to replace, since the way the are soldered onto the diode board. Then again just buy a LED strip.
    A great light for illuminating an area.
