LGM-700 Single Dome Shadowless LED Operating Lamp

The LGM-700 Single Dome OT Light is Shadowless LED Operation Lamp is a top-of-the-range operating theater lamp that was designed especially to be used in modern operating theaters, day surgery departments, and specialty clinics. Having a high optical intensity (160,000 Lux) along with a very thin and aerodynamic design, the LGM-700 Single Dome OT Light operates as a shadow-free illumination device of the surgical field.  LGM-700 Single Dome OT Light, available from Aleef Surgical in Bangladesh at BDT 120,000, is a ceiling mounted operating lamp.

Key Clinical & Engineering Advantages

High-Precision Optical Performance Without Shadow InterferenceThe optical system of the LGM-700 Single Dome OT Light uses an array of 80 high-efficiency LEDs ($1\text{ W} \times 80$) paired with precision multi-angle lenses. This LGM-700 Single Dome OT Light design maintains consistent, shadow-free illumination within deep operative cavities even when the surgeon’s head or hands partially obstruct the light beam.

Maximum Central Illuminance:  ($E_c$): 160,000 Lux at 1 meter working distance.
Adjustable Dimming Range: Digital 10-stage intensity control spanning from 25% to 100%, equipped with an automatic memory function that preserves the last brightness setting when reactivated
Variable Color Temperature: Adjustable between 3,600K and 5,500K ($\pm 500\text{K}$). This lets surgical teams tailor light warmth to optimize visual contrast between blood, organs, and muscle tissues during general surgery, orthopedics, or gynecology.
High Color Fidelity: Color Rendering Index ($R_a$) greater than 95, ensuring accurate anatomical color rendering and tissue discrimination without artificial tinting.

Advanced Lighting Technique and Surgeon’s Comfort

There is an inherent risk of tissue desiccation due to excessive radiant heat generation with traditional light sources for long surgeries. However, the LGM-700 Single Dome OT Light makes use of cold lighting:

Surgeon Head Temperature Rise: Maintained under 1°C, preventing discomfort and fatigue during long procedures
Surgeon Head Temperature Rise: Maintained under 1°C, preventing discomfort and fatigue during long procedures
Zero Harmful Radiation: Generates no infrared (IR) or ultraviolet (UV) radiation ($< 0.006\text{ W/m}^2$ irradiance within the 400nm wavelength), protecting sensitive exposed tissues from premature drying.
Efficient Aerodynamic Dome Structure: Sterile operation room areas require laminar flow air that is generated through the ceiling-mounted HEPA filtration systems. LGM-700 Single Dome OT Light has been designed with a very slim and totally enclosed luminaire head that offers low aerodynamic drag. The outer surface is non-porous and chemical resistant.
