## Description

Welch Allyn (04900) 3. 5v Halogen Bulb

Review: Brand Name - Welch Alyn - Fits perfectly replacing my bulb on a WA retinoscope. No problems. Read some of the reviews that it was not an original WA. The “Bigger box” was not typical WA green and more generic. I’m guess easier for inventory control and fulfillment purposes. The bulb itself was inside a smaller tamper proof original Welch Allyn green bulb casing. Works perfectly as my replacement.
Review: All OK! - Excellent item. Just as in description.

## Questions & Answers

**Q: Does this item come with a bulb or do you have to order one separately**
A: This product is the bulb.

**Q: is this bulb for the 49020 head lamp?**
A: Yes!the same.

**Q: will this work for  Welch Allyn opthalmoscope 72200?**
A: Not sure you are asking the correct question.  72200 is the WA battery , not the ophthalmoscope.  The 72200 will power that bulb and that bulb is for the ophthalmoscope so best is to remove the old bulb from existing device and confirm the number.  Some use this and others similar number 04900 but LED.

**Q: Is that working with welch allyn #25070??**
A: I’m using it with Welch Allyn #11720
