Protect your new light bulbs and Avoid hot-relamping by making sure the power is turned off to the fixture before installation
Hot Re-lamping tests have been shown to shorten, sometimes severely, the life of the lamp being installed in the socket.
Hot Re-lamping Facts
A “hot re-lamp” is the term for changing a lamp when the power is still on at the socket.
A hot re-lamp 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.
Power OFF before you install your new light bulbs
Cold re-lamping or re-lamping 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 re-lamping places the installer at higher risk for electrocution, which is why hot re-lamping violates OSHA safety regulations.
