HID light losing brightness?

I've had a ToPeak HID light for about 3 years now, and lately I've noticed that the intensity of the light has gone way down. Does this mean it is time to replace the bulb? Is the battery not giving the same juice? What can I do to get it back to full brightness?

:imstupid:

Batteries can do a limited amount of charge cycles before losing capacity. Depending on how much you used the light and what kind of battery chemistry it uses, it's possible that it's time for a new battery pack. It might be best to get in touch with Topeak.

It has a Lithium Ion battery.
I'm not losing time (as far as I know). Just brightness...

I think it's the bulb. My 3yo NR hid brightness has diminished with time, especially compared to the newer lights of the guys I ride with. We traded batteries one time and it had no effect on the brightness of either light.

Yeah, hid bulbs last somewhere around 10-times longer than traditional incandescent bulbs. You might have just used up the life of the bulb.

-BB- How's the OC treating you? You're at what, 4 years now? Do you have frosted tips and say "dude" and "bro" a lot now?

If you have a multimeter, measure the voltage of a buddy's new battery vs yours. Bulb or Battery, one of those is bad and there is some testing to be had!

Actually, without the load of the light, unless teh battery is totally destroyed, it will read the same, what you want is loaded Amperage. You need to know how much power is actually flowing out of the battery.
