Surgical Examination Illuminating Light – EM-ZF700/500 Model

The primary difference is illuminance: the EM-ZF700 delivers up to 180,000 lux at 1 m, while the EM-ZF500 delivers up to 160,000 lux. Other core specifications (color temperature, spot diameter range, illumination depth, CRI, power, and working/operating radii) are the same for both models.

The nominal color temperature is 4300 ± 500 K, providing neutral, daylight-like illumination. The color rendering index (CRI/Ra) is ≥97, ensuring highly accurate color rendition for distinguishing tissues, blood vessels, and nerves.

Spot diameter is adjustable from 100 mm to 300 mm. Brightness is continuously dimmable from 1% to 100%. The illumination depth is ≥1200 mm, offering effective deep-cavity lighting for surgical procedures.

The unit is equipped with a high-performance 150 W lamp (the product uses an imported OSRAM lamp per the specification). Rated service life is specified as ≥1500 hours. For replacement parts or optional LED modules, consult your supplier or product manual.

The light uses an integrated secondary infrared filter and multi-functional reflecting surfaces to filter out ~99.7% of radiant heat. Temperature rise at the surgeon's head is ≤1 °C and in the operating field area is ≤2 °C, providing a cold-light effect.

Yes. The lamp is engineered for an excellent shadowless effect. Even if obstructions partially block the beam, the multiple reflector design maintains uniform illumination and minimizes disruptive shadows in the surgical field.

The light is typically ceiling-mounted with a high-quality balanced suspension arm (an imported arm is optional). The arm supports 360° omnidirectional movement, giving flexible height and angle positioning. Best mounting height is 2800–3000 mm; working radius is 600–1800 mm and operating radius ≥2200 mm.

Input power is 400 VA. Power supply requirements are 220 V ± 22 V at 50 Hz ± 1 Hz. The lamp itself is a 150 W unit. Ensure the facility electrical supply and protections meet these requirements.

The EM-ZF700/500 is CE certified and classified as a Class II medical device, indicating compliance with relevant international health and safety requirements. As a Class II device it is designed with double insulation in its electrical construction.

Intensity is continuously adjustable (1–100%). The unit includes a professional color temperature correction/adjustment system designed to maintain accurate tissue color rendition; nominal color temperature remains around 4300 K ± 500 K.

Regularly clean the lamp head and reflectors with approved, non-abrasive disinfectants per your facility protocol and the product manual. Inspect and securely fasten suspension arms and electrical connections periodically. Replace lamps and filters per service-life recommendations or when output degrades. Have qualified technicians perform electrical and mechanical servicing.

Replacement OSRAM lamps, filters and common spare parts are typically available through the manufacturer or authorized distributors. Contact your supplier for genuine replacement parts and recommended part numbers.

Yes. With high illuminance, deep illumination, excellent CRI and adjustable spot size and intensity, the EM-ZF700/500 is suitable for a wide range of surgical and examination procedures in hospitals and clinics. Confirm specific clinical needs and local regulations when selecting equipment for specialized procedures.

Use sterile handle covers or disposable drapes for any handles that must be adjusted during a procedure. Avoid direct contact with sterile fields. Clean and disinfect non-sterile surfaces between cases per facility infection-control protocols.

For professional installation, commissioning and warranty details, contact the authorized distributor or the manufacturer's service department. They can provide site planning guidance (including mounting height and electrical requirements), user training, and authorized warranty service.
