Just to clarify, where i live we have regular power outage but usually does not last more than an hour. Sometime i need enough light to continue doing some stuff and i realise i need roughly 350-500 lumens. The lights i have that puts out those lumens are single 18650 and rcr123 lights which gets hot pretty quickly.
Like 127.0.0.1 and enomosiki suggested maybe i should get a high powered light and run them at medium. And i would like to stick to 18650(max 2) or AAs format. D cells are expensive and tends to leak, also not planning to invest in D nimh + charger.
Any suggestion on light tht has medium/max mode around 350 lumens? Can tailstand and safe to leave unattended?
Thanks.
2x18650 will be better if possible, for extended runtime and not overworking the batteries to death. The lower the battery voltage supplied, the more current the driver has to suck out from the battery to maintain the output.
I've been trying to look at some lights for you, but everything I came across have minor flaws. Here's a list;
EagleTac M3C4 - 2x18650/4xCR123A, parasitic drain
Fenix TK35 - 2x18650/4xCR123A, unstable tailstand
Spark SL6/SL6S - 1x18650/2xCR123A, parasitic drain
ThruNite TN11 - 1~2x18650/2~4xCR123A, unstable tailstand
Zebralight SC600 - 1x18650, parasitic drain, no support for primaries
Lumintop TD-15X - 1~2x18650/2~4xCR123A, unstable tailstand, no output between medium (200) and max (580/720)
My recommendation out of all of them would be the M3C4. It has a stable tailstand, has good array of modes and is capable of handling primaries in emergencies. It has a high parasitic drain, but that can always be remedied by lockout.
