Consists of glass tube with overall length of 23 cm with capillary portion about 8-10 cm long to concentrate the discharge glow. Glass-to-metal seal wires are welded in metal end caps.
These tubes can be operated in standard spectrum tube power supplies of the type such as the catalog Item No. 28-548400, as shown in photo. For intermittent use only, not to be used as a lamp source.
