I have a metal, clamp-on, desk lamp with a swivel head. Today the
compact fluorescent lamp burned out. I bought some new 100 watt
(equivalent) replacements because it is a reading lamp. On the
package, it says 23 watts.
I plugged in the new lamp and "Voila"! Up and running! Within an
hour, the new replacement flickered and went very dim. I switched off
the lamp and removed the bulb. It was hot, but not too hot that I
couldn't take it out right away with my naked hand.
I checked the wattage rating of the lamp. It says..........40 Watt
Type A or smaller lamp. Looking at the package, I don't see a type,
but I bet it is not type A.
I assume the lamp has some kind of thermal protection. The existing
lamp was a compact fluorescent that had been in there for a few years.
After the lamp had cooled down, I put (from another lamp) the same
type that had been in it for years. That one worked. I did notice
that the old type are 27 watt and the new ones are 23 watt, but the
new one only worked for an hour.
After checking all the lamps, the original bulb is bad, but the new
replacement still works. I am now using a old 27 watt that was
exactly like the burned out one. I have switched the new 23 watt to a
free standing lamp that is on a night stand. (It is working fine too)
Anyone have the info on whether compacts can/should be used in
fixtures with Type A spec? Shouldn't the bulb be rated (for heat) at
25 watts even though it is a 100 watt equivalent?

It is hard to tell where any thermal protection would be in the lamp.
