Can anyone recommend a brand or supplier of CFLs that are really the same size as incandescent lamps? I'm looking for bayonet & ES lamps, preferably "100W equivalent" that will fit in some basic (i.e., old & cheap) bulkhead lights.
Won't happen. Equivalent is about a 23w CFL, and in a 100w rated bulkhead they'll overheat. And all 23 watters are bigger than an A line 100w GLS lamp.
Oh, I forgot to specify that I meant the "normal size" (I think that's
22 mm for the bayonet and 27 mm for the Edison) rather than the small ones. I'll have another look at that brand, though (I think I've used some other Megaman CFLs).
I imagine there's some scientific measurement of light output that justifies the equivalence claims, but I agree with CFLs' detractors that the equivalences for individual lamps don't "look right". OTOH, I changed the dining room light fitting from one 100 W incandscent to three 15 W CFLs and the room is a lot brighter for 55% less power.
I had a45W one for a while. Problem with them is if use cap upwards is the heating of the base. In mine the glass became dtached from the base, it was juts held on by the wires.
I thought part of the point of CFLs is that, compared with incandescent lamps, a much higher proportion of the input power is turned into light and a much lower proportion into heat.
