Operating Light – LGM-500/500 Model

The LGM-500/500 is a Class II surgical operating light from Longermay designed to provide high-performance, shadow-reduced illumination for operating rooms. It features adjustable spot diameter, high center illumination, and long-lasting OSRAM LEDs for precise surgical visualization.

The lamp provides up to 160,000 lux center illumination with 10-step adjustable intensity (approximately 40–160 klx), allowing surgeons to select the appropriate light level for different procedures.

Yes. The LGM-500/500 offers selectable color temperature settings (adjustable in multiple steps, typically in the 3500 K–5000 K range) to match tissue color rendering and surgeon preference.

The main light head diameter is 500 mm. The unit is specified with a reflector diameter of 750 mm and adjustable spot diameters — typical d50 around 120 mm and d10 approximately 150 mm (spot range may be adjustable up to around 250 mm depending on model/configuration).

The OSRAM LEDs used in the LGM-500/500 have a rated life exceeding 50,000 hours. The internal electrical and lamp structure is designed to allow relatively straightforward replacement of LED modules; for replacements use manufacturer-approved parts and procedures.

The LGM-500/500 has a high color rendering index (Ra > 95), helping surgeons accurately distinguish tissues and colors during procedures.

Intensity and color temperature are adjusted via an integrated control panel with an LCD interface, providing precise, repeatable settings.

The LGM-500/500 can be configured for ceiling mount or mobile/portable mounting depending on the specific variant and accessory package. Confirm the chosen model at the time of ordering.

Yes. The unit uses OSRAM LED technology, which delivers high illumination while consuming significantly less power than traditional halogen solutions, resulting in improved energy efficiency and lower heat output.

The operating light is CE certified and complies with relevant clinical safety standards, including GB15979-2002. It is classified as a Class II medical device.

The lamp is constructed from high-quality metal and medical-grade plastics. Clean exterior surfaces with hospital-approved disinfectants and non-abrasive wipes. Avoid immersing components in liquids and follow the manufacturer's cleaning and infection-control instructions in the user manual.

Some LGM-series configurations and accessory packages may support integrated camera systems or mounting for video equipment. Confirm camera availability and compatibility with your supplier or the factory sales representative.

The lamp uses high-quality spring arms (e.g., Ondal-brand springs in some configurations) to provide smooth, stable, and long-lasting positioning of the lamp head during procedures.

The product specification lists a 1-year shelf life. For warranty terms, service, spare parts availability, and maintenance contracts, contact Longermay or an authorized distributor for the specific terms applicable to your purchase and region.

Installation should be performed by qualified biomedical engineers or authorized technicians in accordance with local electrical codes and the manufacturer's installation guide. The light is powered by standard electrical supply for medical devices—confirm exact voltage and power specifications in the product manual or with your Longermay representative before installation.
