Default Re: Lamps for lamp limiters

For the amount of use a lamp limiter will get, and with the lamp always under-run (unless there is a serious fault in the set), it is likely that the lamp will last for many years, probably decades. If it is in an enclosed fitting it shouldn't get broken either. One in use and a couple of spares would probably do us for life! So no need to stock up with loads of them.

Another area where filament lamps are still used is oven lights, because LEDs cannot withstand the heat. I think they are 15W, in which case 4 in parallel should work. Maybe even switch bulbs in or out depending on the power rating of the set being tested? I haven't tried these though.
