Yeah, that thing's getting towards silly bright. There's a reason it has a fuckhuge radiator built onto the backside... and needs a 4 AA battery pack offsetting it with 2 band strap (round the head and over the nugget).
It does have low power options both for the primary spot beam as well as the 4 area lights, so you're not on AGHMYEYES mode the whole time, although it's fun since it kicks on in death star mode. It would be cooler if it had a Pthewwwwwww sound when it turned on like an energy rifle having a magazine slapped in it or something.
Regarding the batteries for yours, the Apex is nice in that it has a low battery warning, but between different intensity for the spot as well as the floods it has lower voltage failover modes so you can milk those batteries till they're totally done, or you don't need a light anymore because you're done.
I also still really like Streamlight Sidewinders, as the combination of multiple colors (white spot, red/green/blue floods all by physical toggle)as well as intensity levels by holding down the switch, plus a rotation capable head and a clip that allows hands-free either by tossing it on an epaulet/hat brim/helmet bolt/MOLLE/whatever or setting it down with it rotated where you need light.
Then there's my Final Solution of my Fire Vulcan LED. Yeah, it's only 160ish lumens, but it's a tight as fuck beam that cuts through airborne contaminants, has a really nice charging base, and the rear LED's are nice for using it as a stroll-about light. Plus a seatbelt buckled shoulderstrap since it's intended as a grab off the truck firefighter's light.
When I still wore turnouts, I had a Fire Vulcan on my side, Survivor LED on my chest, and a Vantage mounted on my helmet. I looked like a zombie apoc rave with all my lights on, but at least I could find my way to victims and/or the fuck out of a building if I needed to bail out. Yeah, I like my streamlights. Still need a new battery for my Stinger LED, and I'd like to get some Ultrastinger LED's. Rechargeable lights are just fucking handy, especially since I hardmounted chargers in each vehicle we have had. That way, I always knew beyond the wally world floodish/laser cheapo lights I keep in each vehicle, I also had a Mean Beam onboard if I needed it.
