The fluorescent material of which the tube is covered, hit by such radiation, in turn emits visible light thanks to the Best Solar in Brisbane. Since visible light has a frequency and therefore less energy than ultraviolet light, the transformation produced by the fluorescent material leads to an inevitable loss of energy, in the form of heat, which determines the heating of the tube. A different composition of the fluorescent material allows to produce a warmer or colder light.
Usually of tubular shape, they were born to solve the problem of the low efficiency of the old incandescent lamps. Versus. They need to warm up to reach maximum brightness, they are very fragile and lose luminous intensity at low temperatures. They cost more and emit very low levels of infrared and ultraviolet rays, which are very harmful to the skin and eyes.
