Replaced the rechargeable battery and it seems fine. Replaced the 3100-U bulb and have no light! I suspect the bulb is bad.

Beware - did not work for more than a few seconds.
Purchased this to save a couple bucks from the name brand and... the light color is different than the OEM halogen, and in my case it worked for 30 seconds or less and quit. Seller and Amazon refunded the purchase right away. Do yourself the favor and buy the name branded lamp.
