The relevant measurement of output is lumens - 1,000 vs. 640. Beam distance or throw should be considered with quality of fill or spill. I have a laser which absolutely tromps both in terms of beam distance, but is useless as an inspection tool. That big, long, obsolete Streamlight battery is rated at 2,200 mAH whereas the 16550s go to 5,000 mAH and are about 1/2 the size. My light drops into my flashlight pocket and doesn’t require a holster.
In another 5 years they will all be obsolete, one of them already is.
Fenix UC35 LED Flashlight Is the smaller version of what nick posted. It is blinding. Has 4 brightness settings and lasts a few inspections. Comes with rechargeable batteries, charger, & holster for $80.00. I played with a lot of them at the Vegas convention. This one is lightweight and easily fits in any pocket. I haven’t used my stream lights since
What I really miss in the old maglite, is when I get into an attic and there is some type of critter nest (thank God we don’t have snakes here), would like to have something to swing before I start screaming like a little girl as I fall down the ladder…
