Professional Ophthalmoscope Bulb - length 24mm

All Keeler instruments use genuine Halogen and Xenon technology, yielding a brighter, whiter illumination and a longer life.

Look at the bottom of your bulb to identify if your instrument is 2.8v (blue - dry cell battery) or 3.6v (red - rechargeable)

Measure the length of the bulb as shown above. The length of a Proffesional Ophthalmoscope bulb is 24mm.

Accurate diagnosis depends upon a number of factors. Of these, top quality illumination ranks as one of the most important.

Only excellent visualisation allows you to use your diagnostic skills to the full.
