一種新型照明系統具有許多優點，可以用于普通外科、門診手術以及重癥監護。

Harmony LC照明系統是Steris(Mentor, OH, USA)的產品，增加了可操作性，照明強度高，顏色合適，降低陰影、空腔照明性能都很優越，外觀調節能力很強。這套系統使用了特殊懸掛能夠補償保證最佳可操作性的懸掛軸。

Harmony系統使用了WaveLens工藝，能夠確保在調節外形的時候不會影響焦距。其他特點包括綜合手柄控制能夠調節外形、強度和焦距；冷鏡面發光器能夠過濾患者散發的熱量；墻面放置的控制面板包括發光二極管(LED)指示器能夠顯示照明狀態和可選擇的光視頻相機的狀態。

Versatile Lighting System
 
A new lighting system offering a number of advances is designed for use in general surgery, outpatient surgery, and critical care.

The Harmony LC Lighting System from Steris (Mentor, OH, USA) provides improved maneuverability, high brightness intensity, proper color rendition, excellent shadow reduction, optimal deep-cavity illumination, and superior pattern-size adjustment. The system uses a special suspension that can compensate for considerable shaft displacement for optimal maneuverability.

The Harmony system employs WaveLens technology, which allows adjustment of pattern size without losing focus. Other features include integrated handle controls to adjust pattern size, intensity, and focus; cold-mirror reflectors that filter heat away from patients; and a wall-mounted control panel that includes light-emitting diode (LED) indicators to show lighting status and the status of the optional in-light video camera.
