I'm intending to start off my first amp build by building a bulb limiter, safety first and all that. Standard incandescent bulbs are pretty scarce round here now, amazon/eBay seems the only real option. I can however get some Halogen based ones, still not cheap but I can get them in the shop over the road. They come in a range of wattages from 30-100ish (these are the rated W not the "equivalent"). Is there any issue with Halogen bulbs in a limiter? From a pure limiting point I cant see any issue but I remember them being rather temperamental and I wonder if they might not last very long? If I do source some standard bulbs, is the bulb life in a limiter okay or do I need to get a reasonable number of spares?
