harbor freight quantum 588 lumen zoomie

this is a much cheapened version of the common x700 zoomie with an xp-l.
too short stock to take 18650 without removing spring.
and worst yet is optic is pressed in with a ring.
least mod friendly generic zoomie so far.
out of package it works fine other than aaa cells are a lousy power source for this type of light.

Maybe a 18500 would work? Usually, the 3xAAA holder (or 4xAAA in this case) is long enough that a 18500 would fit in its place. You’d need something to take up the slack in the diameter, though. Is there no way to get the head open, to get access to the LED and driver?

Also, with 4xAAA, you actually have overvoltage, so the driver may be a buck, in which case, you’d get just a little more current to the LED than you’d expect from AAA. You could try Eneloop, since the lower voltage of rechargeables shouldn’t be a problem when using 4xAAA. Eneloop can support a surprising amount of current draw.

its not a buck.
looks like 4 sot-23 mosfets and a 8 pin micro.
desoldering the spring from the driver and spreading the solder to the center of the pad to build it up a bit allows an 18650 to just fit.

Any detail leads on MODS?

Related note : used 18500 to power this with couple to avoid rattle. Works pretty good.

its not very mod friendly.
had to glue the optic back in when i was done. the retainer ring got trashed on removal.
already has a decently driven xp-l so not much to gain anyway.

True indeed. On related note, the light is not water resistant at all. Accident dropped in water. Water seeped into barrel and flooded the lens. Condensation on lens. Can not open to wipe clean. No more worthless junk from HF for me.
