I try to be a little ready for anything; the expenses are many (from the provisions to the maintenance of a lot of equipment); for the lighting I have to stay on the budget and for my protocol I have 3 flashlight for daily use, always present on me, and 5 in case of rapid departure from the home (or even from the city); I tried to optimize them and make them better, rational, without many modes (3 out of 5 have only one mode, but different intensity) and focusing on redundancy; because a single flashlight, however good, could get lost, fall and be irrecoverable, and many other things.
3 out of 5 use the P60, so each one is also a replacement for the other; all 18650 (but if I use a flashlight I have 4 spare batteries).
For the “durable” flashlight I have two simple Ultrafire 503b SS (one in use, the other for spare parts), the P60 module is tropicalized, components immobilized and coated with paint; the led is glued (as well as being welded, of course). frontally they have a 3mm mineral glass (it comes from spare parts for diving watches, there is no o-ring gasket, there is paste for the engine head) and also the tailcap has undergone some changes. In use will be: one made of steel, three made of aluminium and one made of plastic (let’s not underestimate plastic, it has many interesting features, such as, for example, being safely introduced into a high voltage switchboard)
