L1835 high-intensity VUV deuterium lamp. Water-cooled. 115-400 nm.

Overview:

 

The L1835 provides three to four times higher radiant intensity than a conventional 30 W deuterium lamp. The 150 W lamp is enclosed in a cylindrical metal jacket specially designed for water-cooling. The advantage of water-cooled lamps in comparison to air-cooled types is that the heat loss from the lamp is removed more quickly, ensuring high stability.
