I agree the lanterns are great for tracking. The color definition of the light is super to alot of flashlights. These days you can get into the different color temp lights. A High cri or warm/neutral tint beam in the small hand helds will be very similar light quality to the old lanterns. A 1000 lumen neutral tint flood beam handheld is much easier to pack and not having to go the the truck or house to get it is a big plus. The only issue is having spare batteries on hand. My floody 18650 flashlight lights up a 20 plus foot swath of ground with nice even good tinted light.
For blood tracking purposes only I'd be willing to bet all these super bright lights wont hold a candle to an old fashion lantern. Maybe something about the light spectrum lantern throws...I don't know, but I would challenge u (if u got a lantern laying around in ur camping gear) take it with u next time and side by side compare. U might be surprised.
Just general need for a flashlight then those super brights are awesome. My friend has 1 and it is crazy bright. I only carry a cheap headlamp and little single AA flashlight as a backup... Never felt I needed anything like what u guys are talking about.
