I think I'd like to go with 2 tubes with a lower output from each if posible for a more even ilumination of the tank at night. Each tube is rated at 3W which means a 250MA draw at 12V. I'm trying to size a transformer to run 2 of these. If I go with a 6V transformer does anyone know if it will still draw 250MA making it 1.5W, or will it draw 500MA each?
