The only room we use the 100w bulb is the computer room. Higher ceiling. The problem is that we have a dimmer switch and we haven’t been able to find a spiral 100w that is made for dimmer switches.
I don’t use many 100W bulbs, but still stocked up on I think 32 total bulbs. Those will last quite a few years. But I do use many 60Ws in fixtures that use three 60s, plus many of the three stage lamp bulbs. I’ll probably really stock up on 60Ws, but I’m not sure the three stage bulbs are being outlawed. Need to find out for certain.
That will be a good place to put LED bulbs first. High ceilings stairwells, difficult to get-to locations really benefit from long life bulbs!
The savings of lives and injuries from falls more than compensates for the added costs.
Not to recommend them, but they do exist.
