When electricity enters a CFL, mercury and argon fumes inside the bulb produce invisible ultraviolet (UV) light. The white powder coating inside the glass tubing of a CFL contains a fluorescent coating. Ambulance fees for seniors and pensionersĬompact fluorescent lamps (also known as CFLs or energy-saving light globes) are a common lighting choice in Australia since the Australian Government began to phase-out the use of incandescent light bulbs in 2008.Assistance with travel costs to receive medical care.

Older CFLs used large and heavy magnetic ballasts that caused a buzzing noise in some bulbs. CFLs with decorative covers like globe or reflector shapes have a unique design challenge that results in the tradeoff of a slower warm up time, which is why these CFLs take longer than bare spirals to reach full brightness. This entire process typically takes 30 seconds to 3 minutes to complete, which is why CFLs take longer than other lights to become fully lit. A CFL’s ballast helps "kick start" the CFL and then regulates the current once the electricity starts flowing.
This generates invisible ultraviolet light that excites a fluorescent coating (called phosphor) on the inside of the tube, which then emits visible light.ĬFLs need a little more energy when they are first turned on, but once the electricity starts moving, CFLs use about 70% less energy than incandescent bulbs. In a CFL, an electric current is driven through a tube containing argon and a small amount of mercury vapor. In an incandescent, electric current runs through a wire filament and heats the filament until it starts to glow. CFLs produce light differently than incandescent bulbs.
