How to Choose the Right LED OT Lights
Different procedures require different lighting specifications:
| Surgery Type | Light Requirements |
| General Surgery | Medium-to-high intensity, adjustable focus |
| Orthopedic | Deep cavity illumination, high shadow dilution |
| Neuro/Cardiac | Extremely high precision, color rendering |
| Minimally Invasive (Laparoscopy) | Compatibility with camera systems |
| ENT/Dental | Small focus field, high mobility |
Brightness (Illuminance / Lux Level)
Measured in lux (1 lux = 1 lumen/m²):
| Application | Ideal Lux |
| General OT Use | 120,000 – 160,000 lux |
| Deep Cavity / Cardiac | 160,000 – 180,000 lux |
| Minor Procedures | 80,000 – 120,000 lux |
Color Rendering Index (CRI)
- Measures how accurately colors appear under light.
- CRI ≥ 90 is essential to differentiate tissues and blood vessels.
Color Temperature (Kelvin)
- Measured in Kelvin (K), usually between 3,500K and 5,500K.
- Look for adjustable color temperature (warm to cool white) to suit different procedures.
| Color Temp | Effect |
| 3500K (Warm) | Natural skin tones, relaxing |
| 4500–5000K (Neutral) | Balanced view |
| 5500K (Cool) | Enhances contrast, good for vascular work |
Shadow Reduction & Light Field
- LED lights with multi-reflector designs reduce shadows from hands or instruments.
- Depth of illumination: At least 1,000–1,400 mm is ideal for deep surgeries.
- Light field diameter: Adjustable (standard is 180–300 mm)
Heat Management
- LEDs produce less heat than halogen, but effective heat dissipation is still essential.
- Look for cool-to-touch heads and fanless silent operation to maintain OR comfort.
Mounting Type
| Mounting | Use Case |
| Ceiling-Mounted | Most common, permanent installations |
| Wall-Mounted | Small rooms or backup lighting |
| Mobile/Floor Stand | Versatile, ideal for outpatient/minor ORs |
Camera and Monitor Integration (Optional)
- In-built HD or 4K cameras are available for teaching, documentation, or MIS.
- Some systems allow video routing to external monitors or PACS.
Sterile Controls and Adjustments
- Touchless sensors or sterile handle control options for:
- Focus
- Intensity
- Light field size
- Color temperature
Battery Backup / UPS Compatibility
- Essential in regions with unstable power
- Ensure light heads can operate during power outages via UPS
