These are common lamps which are frequently found in corridors stairwells and the like.

Also called butterfly lamps by some people they have a reputation for reliability and long life.

They are also frequently used for emergency lighting.

They must not be used with presence detectors or PIRs as frequent switching ruins their life, they like to be left on for long periods.

There are copies coming out now GEs patent has expired we don't stock these as they do not have anything like the life of the branded lamp.

The system will not let you order lamps that don't exist i.e 2 pin 38 watts etc.
