    Heatsinking

    I'm in the process of making a headlight for dentistry. Plan to run 1 CREE Q5 at either 350 mA or 750 mA. Diameter of the base of the unit will be 20mm just wondering how thick the alu bar heatsink should be. Ballpark suggestions or more accurate advice would all be greatfully received. Dave

    knog 605/305

    does anyone here have any of these lights? if so what do you think of them. Specs on the website seem a little optomistic.. quotes 450 lumens for the 605 and 350 lumens for the 305..

    battery for bike lights

    Just wondering if it's ok to join two of these batteries (Amax 7.2v 4300mah- NimH battery pack for rc toys.) in series to make one battery pack. If so can you recharge them as 1 battery or would you have to charge them seperately??
