    Default Data Bank 70

    One day I was sitting looking at a bunch of Cree LEDs on my bench and wondering, "what can I do with these?" So off I went trying to make something worthy of the black hole.

    The Data Bank 70 uses A123 Systems M1 batteries and aspheric collector lenses. The battery packs are made from Mag 4C tubes. The aluminum plate weighed in at 9lb after machining. It is all one piece of aluminum.

    Power Specs:

    70 Cree XRE P and Q bin white LEDs
    each LED driven at 1800mA
    total power of panel just under 500W
    LEDs are three in series to the battery pack
    there are two packs of batteries
    each pack has normal voltage of 13.2V
    33+1 LEDs on battery pack 1 (single LED on an STFu)
    36 LEDs on battery pack 2
    each pack of batteries is 4 A123 bats in series
    each pack of batteries is running over 20A
    run time is about 5 to 10 minutes
