I have have 4 of these over the last ten year . two of they be still go strong , of the other two , one be lose & the other break -lrb- I keep it for spare part -rrb- . of course the current led technology blow away the traditional bulb but they durability , ease of use and availability & affordability of part & upgrade make for a quality , highly adaptable flashlight . I have never use the ` candle ' mode but it be good to know it be there if I ever need it . to this day , I carry one on both tool belt , my ` regular ' , all-purpose belt and my heavier , framing-rig belt . this flashlight be a staple in the trade , law enforcement , engineering and everything in-between . the lead upgrade for this be ok but it be almost cheaper to just buy a mag lead flashlight except that it would be a shame to throw away this light because we buy the lead one , imho . the sheath be durable but lack a way of secure the tool so that it do not slip out and my biggest complaint be that I have to really tighten the head off to keep it from spin on when I sit down and\/or brush it up against a wall every so often . I buy the accessory kit for this early on but it be nothing special . I be wait for these to burn out or break before I buy the lead version , judge by my experience w \/ these , I be go to wait for long time .
