If you can get on with the bottle battery then that seems very reasonable to me. I’ve chopped and changed a few Lupines including that one, currently on a Tesla which is great. The only problem I’ve ever seen is the battery connector contacts carbonising and needing cleaning or cable replacement. Nicely made lights. I guess things have moved on with cheap lights but the Tesla type copy I had a while back for 50quid wasn’t in the same league of assembly and what not.
I guess it’s all changed now that these light come pretty much free with. Chinese takeaway leaving people more money for the enhancement of their Dandy Horses ;o)
Another vote for Swinnos in Fenton here too.
