Easy to use. Manufactured by Everready First Aid. Made in United States. Review: It works - Our Otoscope stopped working after a fall and replacing it was just not in the budget. I did some searching online and found that sometimes the bulb just goes out. For 14 bucks, it wasn't going to hurt to try. It came in very quickly and after we swapped out the bulb, it worked like a charm! I'm glad this part was so easy to track down and the install was a wiz. Now we are up and running in almost no time at all. Review: Worked for me. - I purchased this replacement bulb for my otoscope. I had read other reviews and was concerned that this product was not a genuine Welch Allyn part. Thus, I contacted the company, and they assured me that although the item will not arrive in a Welch Allyn green package (the bulb comes in a small plastic bag) that it is made by the same company that makes the Welch Allyn bulbs. The first package that they sent was tampered with and the bulb was stolen. Dynamic Lamps promptly sent out another bulb at no expense to me. Customer service was quick to respond to each of my e-mails to them. I greatly appreciated this. While I am not an otolaryngologist, I really can't tell the difference in the light output. It looks the same as my previous bulb. I would purchase this bulb again from Dynamic Lamps. ## Features - For otoscopes/illuminators and transilluminators/tongue blade holder and handle adapter - 3.5 voltage - Sold as each - Country of origin: Mexico ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.6 out of 5 stars 206 Reviews | ## Images ![Welch Allyn 03100-U Halogen 3.5V Replacement Lamp - Image 1](https://m.media-amazon.com/images/I/51Nci7EB1vL.jpg) ![Welch Allyn 03100-U Halogen 3.5V Replacement Lamp - Image 2](https://m.media-amazon.com/images/I/71WyE2nSDGL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ It works *by J***B on December 12, 2023* Our Otoscope stopped working after a fall and replacing it was just not in the budget.
