I loved my old carbides as at least they were reliable and if operated right I knew how much light I would get.... Then I got one of the big ones with a gas generator that lasted yonks.
My experience of 2nd hand electric lamps back in the early 80s was they were unreliable and prone to letting me and my mates down (having been told 'you'll get hours out of these). We wasted a load of dosh on some only for 3 out the 4 to fail well into a longish trip. Fortunately I was not that trusting and had a couple of old Carbides sufficient for us to get out!
we stuck to Carbide again for a long time after! 😉
Aaaaaaaaaaaaaaaaaaagh Creeper!!!!!
