General Specifications for Chinese "LED OT Light 700/700" Models

Specifications for these lights are generally similar across various Chinese manufacturers, focusing on high brightness, energy efficiency, and low heat emission. 

• Illuminance: Typically ranges from 160,000 Lux to 180,000 Lux per dome at 1 meter working distance.
• Color Temperature: Usually adjustable, with a common range of 3500K to 5000K or 3800K to 5500K, allowing surgeons to adjust for optimal tissue contrast.
• Color Rendering Index (CRI/Ra): Generally above 90, often cited as 93 or 95, for excellent color accuracy.
• LED Lifespan: A significant feature is the long life, typically ≥50,000 hours, with some sources citing up to 80,000 to 100,000 hours.
• Illumination Depth: Often specified as ≥1200 mm (or over 1000mm), ensuring light penetrates deep into the surgical site.
• Spot Diameter: The light field size is typically adjustable, ranging from 120 mm to 300 mm.
• Temperature Rise: Known for a "cold light" effect, with temperature rise at the surgeon's head or surgical field generally <1°C or ≤2°C.
• Power Supply: Wide voltage compatibility, usually AC 100-240V, 50/60Hz.
• Control System: Often features micro-computer digital control or touch LCD screens for adjusting brightness and color temperature.
