Spotted light source

The lamp we received emits intermittent light resulting in some faint/shaded areas in the projected light pattern coming from the ophthalmoscope. When we replaced the Welch Allyn lightbulb, the shadows disappeared. Wiping the bulb with alcohol didn't help. I wish I had just bought a Welch Allyn light bulb and not been trying to save a few bucks.

Pros
  • Disclaimer. Our 04900 lamp is a direct replacement for the Welch Allyn 11720 lamp and other lamps just mentioned and is not manufactured by Welch Allyn.
Cons
