Halogen Shadowless Theatre Light

Light Source: Tungsten‐halogen bulb (commonly 24 V) Illumination / Brightness: Typically around 50,000 to 100,000 lux, depending on model Color Temperature: Around 3,300 K to 4,500 K, giving a near‐daylight / warm‐white light Color Rendering Index (CRI): High, often ≥ 90–95%, for accurate tissue color rendering Spot Diameter / Focus: Adjustable; typical head sizes allow a focal spot of 160–280 mm (or similar) Depth of Illumination: Can reach ≥ 500 mm, giving good penetration into surgical area Temperature / Heat: Halogen lights generate heat, so there is usually a filter or design to limit heating of the patient and the surrounding area. The rise in temperature at the surgeon’s head is often kept very low (≤2 °C in some models) Mobility: Mounted on a stand with castor wheels (often lockable) for easy repositioning
