I need to replace a magnetic ballast in a F40T12U fixture with an electronic one. I need it be instant on. The last one I bought about 5 years ago said it was rapid start but acted more like a pre-heat ballast, there was a delay of a couple of seconds from when the switch was turned on before the tubes would light. I didn't like that much.
Anyone know of ballast that can turn on 2 U bulbs instantly?
