    it says 6.2 Watts for the 50mm one

    so with a formula of Watts = Volts x Amps or Amps = Watts / Volts
    work out the current drain

    once you have worked out the current drain then you need to work out the battery life for a
    given A/hr rating of our battery

    for example ..... a battery with a say 120A/hr rating would last ~ 240 hrs give or take a bit
    with a 500mA drain

    find out the rating of your battery its prob is on the battery label

    post your results and we can check them :)
