BIRNS General-Area Chamber Light


BIRNS General-Area Chamber Light w/Switch

The BIRNS General-Area Chamber Light™, Model 4133, has all the industry-leading features of the regular BIRNS General-Area Chamber Light, plus a convenient On/Off switch.  It provides perfect general-area illumination inside pressurized chambers and has a superior thermal design, which permits use of higher-output lamps, so it can be tailored to provide even more chamber illumination. The attached cable length is 1.8m (6′), but on special order it can be any length specified. The unit comes complete with choice of 12V or 24V lamp (power ratings ≤28W).


The low-voltage BIRNS General-Area Chamber Light is designed specifically to safely provide white light illumination inside pressurized HeO2-atmosphere PVHO chambers. Superior heat-sink design, helium release valve, low-voltage lamps and a case ground (earth) connection make this Chamber Light a powerful, proven choice for PVHO applications. All BIRNS Model 4133 lamps operate well on AC or DC.
