Amondotech 3152 35W HID repair or replace

How good is this light? It’s been used mainly for modular home crawlspace inspections the past 10 years, and just recently it won’t turn on. A multimeter says the voltage on the battery is 13V. It may have gotten wet internally. There doesn’t appear to be voltage on the wires that lead to the light when the switch is turned on. I didn’t know what else to test.

I’ve been looking for specs on it, so I could find a replacement which is better or equivalent; but I haven’t had any luck. A light which illuminates a wide area maybe 100 feet out would be good. I don’t have many lights, but something like a OxyLED MD50 Super Bright 900 Lumens CREE T6 LED Torch, with a 18650 Battery isn’t enough. It needs to have a wide much brighter throw.

I’ve seen some inspectors recommend a Fenix LR35R. Would that be a good light? Or should I be trying to repair my 3152?

I would at least take it apart to see if anything looks suspicious. There are several posts here on BLF on the Amondotech 3152 that may help. Being a 10+ year old flashlight, it may have just have stopped working. But if you suspect water damage, that would be the downfall for any flashlight.

I’d rather use my flashlight around the house than turn on the lights.

I took it apart, but didn’t know what to check on the ballast or if i could get a good shock. I took the lamp off and tried measuring the voltage to it, but didn’t get anything, so it’s something before the lamp probably.

I have a very similar HID spotlight that was sold here in Canada under a different brand name.

I would pull the battery out and do a load test on it as the first step.
Connect a load that draws several amps to the battery and use your multimeter to see if the battery voltage across the terminals sags beyond normal under that load.

Hooking it up to a car battery, which is being used to power a radio, didn’t help. I took photos of the components, but didn’t see anything that I knew how to repair or test. Probably time to give up. Thanks for all of your suggestions.
