Swap tungsten for LED

Convert your slit lamp today

Enhance your older Haag-Streit slit lamps by converting them to use a 14mm LED illumination system. Many eye clinics are still using tungsten bulbs in slit lamps, which can lead to equipment down-time when the bulb needs to be replaced. Frequent bulb changes in busy clinics can be costly. LED illumination reduces energy consumption by 60%, lasts up to 150 times longer than a tungsten bulb and has the added benefit of providing improved illumination of the anterior segment for clinical diagnosis.

An LED enhancement is quick and simple to perform, with little downtime. Our Service Engineers will visit you and install the conversion kit in just a few hours. For further information, click here to download the leaflet, or alternatively call the HS-UK Service Division on 01279 456314 or email
