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.
Megaman do some fairly dinky ones. Their candle bulbs being pretty much spot on the size of the bulb they replace.
I have yet to see a CFL that can do the equivalent of 100W regardless of claims to the contrary!
I recently bought a Philips from Sainsburys - supposedly (I believe) '120W'. It might be a the equivalent of a really good 60, but 120 it ain't.
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.

Have a look at the Megaman range - I've been extremely impressed with them:
very expensive and didn't last very long. Perhaps I was just unlucky.

Oh, come on! I don't know what you've SEEN, but I have 65 watt and
85 watt CFLs in use here in standard lamps.John
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.
And what do those claim to be, floodlights? ;-)
Got a link?
I have a couple of the candle ones used in a three bulb lamp. With one
40W incandescent the combined result is ok. You do notice the difference when the incandescent fails though!65 W input?
A number of online sellers i imagine.
Not 85, but these go up to 65
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.
It's the answer to Q1 that gets me: "... we use something called Ingenium technology".
I hope they remembered to top up the flux capacitor with Unobtanium.
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.
Well that is true but they still get hot.
