    Hello

    I bought 5 pieces of this lights.
    http://www.dealextreme.com/p/9-6w-1...ree-filters-for-panasonic-cgr-d16s-more-42304

    Good lights but one problem, they don't have a DC input to have it constantly on.
    So I have altered all the lights so I can plug them all into a box and from that box I would like to connect to a 220v.

    So my problem is that I need a big adapter to run them all in one.I have measured the current of the light and it is about 1200mah each at full power. So basically it is 5 x 1200mah that I need right ?

    I was thinking about using a PSU from a PC, using the 12v line and lower it to 8v or so. They recommend DC7.2-8.4V for the light. The question is, how would I go by doing that, should I make a regulator for this, if so. Any idea on schematics for it ?

    Any other way of doing it ?



    Best thanks.

    Ps. It would be a bad idea to run the lights at 12v right ?

    It has batteries? Then just wire a DC voltage to the battery inputs and it should work. If you want to run them all off of VAC, then you will need a very basic linear power supply. Plenty of results on google.

    Ok, sounds good. But just to be safe because I'm still a noob in electronics like this.
    Will I need anything else for the circuit, or is it just 12v to that VR (which stands for?) and from there to the light ?

    Thanks for the help btw :)

    There is a circuit in the datasheet for the Voltage Regulator I linked to. You should probably make that circuit for each light. Of course you can always use another VR and then you should consult the appropriate datasheet for the circuit.
