In an average February, Rome has four days that dip below 32 degrees F; the average high is 56, and the average is 40. Paris averages 12 days each February below 32 degrees F; the average high is 45 and the average low is 34. Only you know what constitutes weather that is too cold to enjoy.
A fluorescent lamp or a fluorescent tube is a low pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the bulb to glow.
With a normal bulb the light is not bright enough to see although some fluorescents will glow slightly in a dark room. With an LED light it only needs a small current to be fully on and hence the problem. Using a switch with a larger gap or using a DP switch as JP suggested should solve the problem. Mar 16, 2012.
