Now there is a solution for those hard to find flourescent appliance bulbs-replace them with a metal halide bulb!I may have to do that for my WP and KN washers that need the new flourescent appliance bulbs-NO ONE has them here!But the metal halide bulbs and ballasts are EASIER to find!And the MH bulb should last longer,too.Like the vapor tight fixture maounted in the control panel.NEAT!!And the washer chassis serves as a heat sink for the ballast!It will last longer,too!If only light fixtures had better heat sinks for the ballast and igniter.Stay tuned-you may be able to get Digital electronic ballasts for such bulbs,Venture,Advance,are working on them.The photocell is interesting,too.Many fixtures have them so you could use the cell from a fixture.
