The problem

Surgical headlamps cause occupational injury — and shorten careers

68%
of high-frequency headlight users report aggravated neck symptoms
Sahni et al., J Spine 2015
34%
develop clinically confirmed degenerative cervical disorder
vs 7% of low-frequency users
3.2 yrs
shorter operating careers for surgeons who wear headlamps

The solution

ErgoLite — Ergonomic Responsive Lighting

Patented orientation sensing technology that continuously monitors the operator's head angle using onboard accelerometers and motion processing. The system responds in real time — no manual input required.

LOOKING DOWN

Full output

Surgeon looks at the operative site. Headlamp delivers full intensity where it's needed.

LOOKING UP

Auto-dim engaged

Surgeon looks up — headlamp automatically dims to protect colleagues from glare.

LOOKING DOWN

Instant restore

Gaze returns to the surgical field — full intensity resumes instantly. Seamless cycle.

Integration economics

Low cost to integrate, high value to capture

ErgoLite requires no proprietary hardware. Standard ICs from multiple vendors. Integrates into existing headlamp designs without industrial redesign.

Market opportunity

A $430M market competing on marginal improvements

Current competition centers on lumens, weight, and battery life — marginal spec improvements that erode margins in an increasingly crowded field.

ErgoLite is a category-creating differentiator. It addresses a documented occupational health crisis rather than incremental specifications. No competitor can legally offer it. Surgeon wellness is increasingly a purchasing factor for hospitals and surgical centers.

Class I medical device classification — minimal regulatory burden for integration.

IP available for licensing or acquisition

Flexible deal structures — exclusive license, non-exclusive royalty, or outright patent sale.
