HD 2010 issue. Very dim.

So I have a hd2010 gray that I use all of the time
For some reason this weekend when I use it it’s very dim. I swapped batterys same thing. Any ideas? With this light not working I am now thinking about rebuilding it.

maybe a bad contact somewhere?

at first i would use a bare wire instead of the tailcap (touch negative of the battery and the bare end of the tube)…
and
open every thread, clean it and try again

These lights had a problem with the reflector bottom touching the contacts on the led. Possibly it has shorted out this way.

Remove all tubes and clean them. 1) remove the tailcap and connect the battery to the battery tube and see if the light works (screwdriver, knife, scissors etc.) 2) Unscrew the bezel a little (or a lot ) then test again as before. If the light still doesn’t work, it could be the LED that died or the driver. You can test the LED by connecting a LiIon cell directly to the LED for a split second to see if it lights.

Any one know where I can get a replacement led and driver? Sorry for the late response. My wife put the light in a desk and I forgot all about it not working until I needed it

fastest place would be mtnelectronics not sure what driver you need but he has everything
but test that led. he also has insulators to keep the reflector from
contacting the board

Thanks!

Do you live in the US?

Yes

the fastest place to order from is mtnelectronics
