100W LED Cold Light Source with Fiber Optic Cable. This 100W ENT light source is designed for low intensity endoscope applications, its intensity is around 15% more than 250W halogen light source, it could not replace our 120W endoscope light source for deep surgery. BASIC PARAMETERS: 1. Led power: 100W. 2. Input power: Wide range from 100-240V/AC; 50/60 Hz, so you use it in any country on this small planet. 3. Intensity: far exceeds 250W halogen light source. 4. Color temperature: 5600K, CRI 70 and 90. 5. Led life: it could last 60000 hours max, 120times of xenon, so you do not need to replace the bulb for years. Note: the above life hour is based on ideal lab test. 6. Connector: Customized connector, it accepts fiber light guides with active areas ranging from 3 mm to 10 mm diameter. 7. Does not emit light in UV or IR. 8. It saves energy for more than 50%. 9. Environmentally friendly. 10. Friendly design, easy operation.
