Product Description

If your slit lamp runs on a P44S pre-focus flanged bulb — also referenced as HS366, Reference 366, or 2518/3 — the Optilight LED Upgrade Module is its permanent solution. Engineered as a direct-fit LED replacement for the classic non-halogen tower-style slit lamp configuration, this module installs in minutes and works across six major ophthalmic instrument manufacturers.

Universal compatibility — one module, six brands

The P44S / HS366 bulb is an ophthalmic industry standard, found in classic slit lamps from Haag-Streit, Topcon, Marco, Burton, Mentor, and Shin-Nippon / Rexxam. The Optilight module matches the same mechanical footprint — including the P44S/E14 flange collar base with 9-hole positioning alignment — ensuring precise optical alignment without any adaptation or modification to the host instrument.

What changes. What stays.

Your slit lamp stays exactly as it is. The only thing that changes is the light source. LED technology delivers a stable, consistent white light from the first second — no warm-up, no color shift, no flickering as the instrument heats up. Heat emission at the lamp head drops significantly, improving comfort during prolonged patient examinations. And the lifespan far exceeds the roughly 100 hours of the original halogen, eliminating the recurring cost and downtime of bulb replacements.
