Dental headlight D-Light Duo

surgicalLEDshadowless

Product overview
D-Light Duo is a compact, dual-LED shadow-reducing medical headlight designed for line-of-sight illumination in surgical, dental and clinical procedures. The ergonomic hinge allows the two LEDs to work as one, producing a sharp-edged, high-intensity light field while minimizing disturbances to the operator.

Key features

• Shadow reduction: up to 70% reduction via line-of-sight illumination
• High brightness: marketed as 150,000 Lux; measured values up to 200,000 Lux at 100 mm
• Ergonomic hinge mount for precise LED positioning
• Sharp edge light field for accurate illumination of the working area
• Adjustable for multi-user environments
• Flip-Up option: retract the lamp out of view when not required
• Integrated cooling system keeps housing cool to touch

Adjustments / Positioning

• A: Adjustable declination angle — direct light to the target area
• A+: Flip-Up — move the lamp out of the line-of-sight when idle
• B: Adjustable convergence angle — adapt beam overlap for different working distances
• C: Adjustable interpupillary distance (IPD) — align each LED to the user’s ocular axis

Included in basic D-Light set

• Carrying case
• Power pack
• Frame / Clip-On / Loupes connection (one option included)
• UV curing filter (dental use)
• Allen key for adjustments
• Power supply
