The KL-LED·STR78/STR78 suits general, orthopaedic, cardiothoracic, obstetric and trauma theatres, hybrid and day-surgery suites, and any operating room that needs two independent light heads. Its case is mechanism and effect. Light from 174 LEDs on two heads reaches the wound from many directions, and each number on the sheet describes what that does for the surgeon.
Brightness and depth come first. Each head gives 160,000 lux at 1 m, the top of the range IEC 60601-2-41 sets for surgical lights, and a 150 cm depth of illumination keeps a deep cavity lit as the head moves. Colour comes next. An Ra of 85 to 100, with R9 and R11 at 97 or above, helps a surgeon distinguish tissue types and blood, and a colour temperature adjustable from 3000 to 6700 K lets the team tune contrast. For laparoscopic and endoscopic cases, endo mode at 15,000 lux leaves enough light to work by without washing out the monitor. The optional camera records or relays the field for teaching and documentation.
The effects need managing. Overlapping two full-output fields raises irradiance at the wound, so staff should know the warning in IEC 60601-2-41 about tissue heating and drying. Handles need a sterile cover or sterilizable grip for each case, as the instructions for use describe. Fixed wiring in medical locations falls under BS 7671 Section 710; the ceiling structure must support the load, and theatre lighting normally runs from a backed-up supply.
Theatre capital projects, NHS procurement routes and overseas health ministries will ask for the device class, IEC 60601-2-41 test evidence and a declaration of conformity. The manufacturer issues the conformity documentation those procurement routes require, and the enquiry team shares it.
