Low pressure spectral lamp for use in the demonstration of mercury spectral lines.
Although the screw fitting fits into a regular E27 lamp socket, this lamp must under no circumstances be connected directly to the mains, but must be used in conjunction with 283090 Spectral lamp housing with screw socket and 284050 Throttle Spectral lamp.
This lamp can be used with the earlier models of spectral lamp housings 283060 and 283065.
