JEVAlux FLL
Flange-mounted LED vacuum chamber lighting
The LED sits outside the vacuum chamber. Its light enters the vessel through a cylinder of optical glass, and a diffusing zone at the end of the cylinder distributes it evenly.
Because the light source stays outside, nothing heats up in the chamber, and consumption is no more than 5 W.
Luminous flux
max. 550 lm
Power
max. 5 W
Flange
DN25KF, DN40KF, DN40CF
Installation depth
50 to 125 mm
Features
- LED light source outside the vacuum chamber, no heating inside the vessel

- easy-to-clean light guide
- FLL-40K-PG with replaceable protective glass, especially for coating systems
- with plug-in power supply and switch for two brightness levels or with 5 m connecting cable
