Choosing the right light source type and voltage for an otoscope is key for getting a clear and accurate view of the ear canal and tympanic membrane. The most common options are halogen, LED, or incandescent bulbs, each with their own strengths: LED bulbs offer bright, consistent illumination and long life, while halogen bulbs deliver a warm, natural light. Voltage, such as 2.5V, impacts the brightness and battery life—lower voltages are often more portable and energy-efficient, while higher voltages can be brighter. The Otoscope Ophthalmoscope Diagnostic Set, 2.5V uses a 2.5V power source, balancing good illumination with portability. This product demonstrates how a moderate voltage can be ideal for diagnostic purposes. There are several options for voltage and light source types available, so you can select the otoscope and ophthalmoscope that fits your clinical or home-use needs best.
