I've had my Sparc for over a year now and until a month ago, its been flawless.  Now, it'll power up fine but won't power down.  I hold the power button until it turns off and when I let go, it turns back on.  Also, when firing (I have it mounted to a MI side rail on my SGL-31), the intensity setting goes from dim to bright with every shot.  Despite the problems, its held its zero perfectly but the power issues on a $200 optic are starting to upset me.

Any ideas?

Weak battery.  It's a known issue with the SPARC.  They act wierd when the battery gets low.

I agree, this sounds like a low battery issue. Try a new battery and then screw the cap down nice and tight. If that doesn't work, definitely give our customer care department a call- 800-426-0048 ext. 4

+1 on the battery.

I couldn't change the dot brightness on mine. Changed battery and all better.
