    Hi, I am new here, I'm hoping I can get some help with building a little power supply.
    It is a NEEWER CN-160 Patent LED VIDEO LIGHT (with 160 individual LED LIGHTS).
    This runs on 6 AA Batteries, but I want to make it able to plug in to use a wall outlet.
    These are the specs:

    Specification:
    Input: DC 7.2V~8.4V
    Maximum Power: 9.6 Watt
    Color Temperature: 5400K (3200k w/filter)
    Average Service Life: 50000 hours
    Luminous flux: 660 lumens
    Runtime: 70-90mins
    Video light size: 141mm x 62mm x 150mm
    Gross Weight: 430g (without battery)

    What do I need for parts and values? and what schematic could I use?
    Thanks so much!

    Get a plugpack (wall wart) rated at between 7.2 and 8.4V and at least 1.5A and you should be right.

    thanks Steve, that's probably the best Idea, but I just want the experience of building it also. I have a workbench and all the tools.

    Greg, please forgive me. The way I said that clearly lacked even a modicum of tact. :eek:
