With the monochromatic white light (reference color temperature = 4200 degree Kelvin) the lamp in the ri-scope L provides cold light and true-color, even illumination of the area under examination.

Lamps with LED technology have a lifetime of at least 10,000 hours (compared to 20-30 hours with halogen and Xenon lamps) and are extremely energy-efficient.

LED illumination is available with all Riester E.N.T. instruments and ri-derma with lithium batteries or Li-ion batteries with alternative handles, Types C or AA.

Considerably higher charging capacity, longer lifetime, light-weight these are the big advantages of the ri-scope L with Li-ion and Li-batteries.

These completely new instruments were developed with input from doctors to set new standards for optical quality, ergonomics and performance options.

Memory effect and self-discharge are no match: the light-weight lithium-ion battery used in the ri-scope L has an unsurpassed lifetime - with higher loading capacity and sustained high-power performance, even after well over 1000 charge cycles.

Nearly unlimited lifetime with the highest luminosity: these advantages make the LED technology used with the ri-scope L so unique. Moreover, the lamp inside the ri-scope L never gets hot, provides true-color, even illumination of the area under examination and is practically guaranteed never to fail, in contrast to conventional halogen or xenon lamps.
