I’ve gone back and forth on this but ended up keeping the LEDs. There’s just no upside that can make it worth it to have the heat issues, melted plastics and other damage associated with incandescent. I had a game which locked on a flasher and destroyed the plastics and plastic support around it. Never again.
Even though Comet inexplicably markets and sells those “make you go bright for 10 minutes!” flangers, they also have more reasonable ones, and the 5-SMD towers are just fine for exposed bulbs. I save the super bright ones for those underneath obscured areas of the play field or under plastics.
