Thrunite HL10. Has both sublumen and single digit lumen modes as well as a top end around 750. I think the mid level mode on down has long enough run times to last the night.
Do you mean TH10? Would a 18650 light be light enough to wear all night?
I'm looking for a headlamp and would like to see some suggestions as to new entries. I like high output but also like sub lumens. I guess the best light for me would be light enough to wear all night but have enough battery to last a 10 hour night shift. Most if not all work would be under twenty feet (electrical panel work) and if longer range I will have a flashlight to tackle those tasks. Could some of these lights be mounted on a hardhat and easily changed in and out? Thanks.
Do you have any idea of how much output you need? A 1xAA headlamp would be about as lightweight as they get and would easily go all night on a "low" setting of 10-15 lm. I was thoroughly impressed with the ArmyTec Tiara A1 Warm. Has a quite nice tint and very smooth, even flood beam that seems about perfect for your uses. Claimed 25 hours on the 9 lm setting, but can put out a impressive amount of light on higher modes if needed. I really liked the UI, also. I can't comment on comfort during extended use, though. If you don't mind CR123-sized cells the Tiara C1 is probably just about as lightweight with still brighter and longer run times.
Similar options from Zebralight (have more output options to select from) are very well-liked such as H52-series, and Fenix has the HL50, but I don't have personal experience. I like the detachable light style headlamps for versatility, but you may prefer a dedicated headlamp.
What do you mean by "easily changed in and out?" I can't comment on hardhat use but I gotta think it wouldn't be difficult. Maybe you could also look at some of the helmet mounted lights such as used by firefighters and such? Most of the lights I mentioned use a pair of silicone rubber loops to hold the light, but pulling the lamp body out is a bit of a chore. I imagine a split clip that the lamp body would easily clip into and out of as needed. You could attach extra clips to anything you wanted--hardhat, belt loop, tool box, a big magnet--and easily fasten the light anywhere you'd like. I haven't yet found such a retention device, though.
