It worked with my Welch Allen portable otoscope.
It worked with my Welch Allen portable otoscope. Make sure to buy the correct model. There are two different type of lightbulbs that are specific to the equipment you may have. Just pay attention to the lightbulb you’re removing and replacing.

Están bastante bien por el precio, pero no esperes una luz fuerte, además no se ajustan totalmente bien en mi oftalmoscopio.

Don’t buy these bulbs for a Zyrev zetalife otoscope.
This product does not fit in a Zyrev otoscope. The info given in the initial review does not tell you this. The return cost is about half the original bulbs price. Beware!!!

A value alternative to expensive Welch Allyn bulbs.
We tend to get about six months out of branded bulbs in our Welch-Allyn otoscopes, but prices have been rising and we're giving these a try since they're a fraction of the price. Initial experience has been promising, but even if these bulbs only last half as long as OEM we'll still be saving money.
