The unique combination of the reusable slip-on polycarbonate filter sleeve and a fluorescent bulb produce more visible light in the safe range than conventional safelights. High Vision Safelights are safe for use with all blue or green sensitive X-Ray film. Safelights must be mounted a minimum distance of 4 feet from film.
You save filter replacement costs when changing the fluorescent bulb because, unlike some safelights, the High Vision Safelight filter is reusable and does not need to be replaced with the bulb.
The safelight has a pull string on-off switch and comes with a six foot 3-conductor grounded cord set. Safelights operate on 118 volts 60 HZ AC .5 AMPS. 20 Watt 25.5 W 1.5 H 3.75 D
Finish: Baked on White Enamel.
