    Dear Sirs,

    I got a transformer from the old circuits which i got from the electronic shop. this is what is written on the transformer.
    Input : 120v 60Hz
    Output: 12v 200mA.
    but there is no where mentioned the wattage.
    how to know how much is the wattage. if i can use this to make driver for fluorescent tube of 17W.

    Please give me some knowledge about this. i have already googled the topic but did not find anything.
    Thank you in advance.

    Power (watts) = volts x amps

    12V x 0.2A = 2.4W
