Superior Lamp Product Tip- Avoid "Hot Relamp"

, Superior Lamp Product Tip -AVOID “HOT RELAMP”

When your customers’ Superior Lamps are about to be installed, make sure the power is turned off to the fixture. This is done to avoid a “hot relamp.” Hot relamping tests have been shown to shorten, sometimes severely, the life of the lamp being installed in the socket.

A “hot relamp” is the term for changing a lamp when the power is still on at the socket. A hot relamp jolts the lamp’s filament when the base makes any positive electrical contact with the energized socket. When you screw in a lamp, you are wiggling the bulb around (which can flex the cold filament) and then a large surge of electricity jolts the filament while it is flexed. This moment of stress can reduce lamp life and cause a premature burnout. Cold relamping (relamping with the power off to the socket) is recommended for all types of screw-in and plug-in lamps. This should particularly be the case when changing Halogen lamps, since they use a more inflexible filament.

Hot relamps should also be avoided with fluorescent fixtures, as you can short out and damage the ballast and lamps. In addition, hot relamping places the installer at higher risk for electrocution, which is why hot relamping violates OSHA safety regulations.

To insure Superior Lamp customers get the best life and most satisfaction from our products, remind them not to hot relamp.
