hi there, recently one of the bulbs in my aquastart 500 has blown! As the tank has 2 switches for the lights i'm guessing there are two individual ones, so does anyone know which bulbs i need to buy for it? I'm AWFUL at DIY so haven't even attempted to take the cover off the lights to have a look, as i'll probably electrocute either myself,or my fish! So does anyone have any idea which bulb i need to buy to replace it, or alternatively, whether i should just get a seperate submersible light? 
Thankyou very much!!!
