    Alegra Contra-angle handpiece with LED+ light

    More colour. More contrast. LED+

    LED+ contra-angle handpieces from W&H offer an incomparably high colour rendering index (CRI). The self-generated LED light is of daylight quality, renders colours naturally and is many times brighter than a conventional halogen light.

    Your advantages at a glance

    • Independent sterilizable LED light
    • High colour rendering index of more than 90
    • Robust design
    • Thermo washer disinfectable and sterilizable
    Daylight quality LED+

    Visual clarity

    A high CRI value significantly improves people‘s sense of wellbeing and ensures greater visibility. Perfect colour rendering has an index of 100. Conventional LEDs only have a CRI of between 60 and 80 and are ineffective in reproducing red tones.

    LED+ contra-angle handpieces from W&H use a new technology: The result is a CRI of more than 90 which means clear colour contrasts and exceptional reproduction of natural red tones in the mouth.
    Absolutely independent

    Micromotor on = LED+ on

    The generator is integrated into the Alegra contra-angle handpieces and is completely independent. Therefore an external power supply is not required. The unique W&H LED+ generator technology ensures perfect LED+ quality, regardless of whether the dental unit, coupling or micromotor is equipped with its own light source.
