(And SimonRl will be glad of this, coz I finally figured out its the batteries not his lamp that's gone south!)
Moons ago I bought a fenix P3d - a fine lamp for aven spotting, nae one of the best lamps for photogagaye, as ever built - however there was a flaw in this, the everlasting dumpy ICR 123 3.6v rechargeable battery! its cycle life is shite!
Is there a one stop larger battery (18650 is summat I've heard about) that is readily available to replace 2x of these things? please no long winded techno answers, just simple places to shop ta!
Better to regret something you have done - than to regret something you have not done.
