BECK CANISTER LAMP. 
This lamp is of solid construction and has an iris diaphragm 
fitted together with a cell in which a colour filter can be placed. 
The light source is a 60 watt Fullolite globe. 
It is a useful lamp for general work, as the light can be readily 
controlled by the iris diaphragm, but it is not sufficiently powerful 
for high power dark ground illumination, and cannot be used for 
top lighting or work with a vertical illuminator, as it has no raising 
motion.
