It also says "2.3 year life" with an asterisk after it (ha ha) and in fine print is says "based on 3 hours per day use". So that's about 3.5 months running 24/7.

WebAnswer: A fluorescent lamp, or 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 lamp to glow. WebA "normal light bulb" is also known as an incandescent light bulb. These bulbs have a very thin tungsten filament that is housed inside a glass sphere. They typically come in sizes like "60 watt," "75 watt," "100 watt" and so on. The basic idea behind these bulbs is simple. Electricity runs through the filament.
