What is the common used artificial light in our life?

Let's have an over view of the 3 common types of artificial light. The traditional Incandescent bulbs were first on the scene. Next, came the Fluorescent Lights and then LED Lights, both bringing advantages in bulb lifespan and energy savings. However, they are all three, still in use with their own distinct advantages and disadvantages.

█ Commercial use - mid 1900s.
█ Uses lots of energy.
█ Generates heat - hot to the touch.
█ Needs to be replaced often.
█ Shatters easily.
█ Light quality is very consistent and close to the quality of Sun light.
█ Commercial use - 1930s.
█ Cool to the touch.
█ Lasts longer than Incandescent.
█ Uses less energy than Incandescent.
█ Still shatters easily.
█ Contains dangerous mercury poses a hazard when broken or during normal disposal.
█ Commercial use - Early 2000s.
█ Cool to the touch.
█ Lasts longer than Fluorescents.
█ Uses less energy than Fluorescents.
█ Does NOT shatter.
█ LED quality is not consistent during production and needs to be classified and sorted at different quality levels after production.
Do you know...Thomas Edison did NOT invent the Incandescent Bulb…
but he did make it commercially viable!

Incandescent lighting uses heat (thermal radiation) to produce light. Sunlight and Candle light are generated in this way. Incandescent Light Bulbs also generate heat (thermal radiation) through a "filament". The filament heats up to produce light like a candle. Read More

Fluorescent Lights have been commercially available since the 1930s as long Fluorescent Tubes. A smaller bulb like CFL (Compact Fluorescent Light) only became widely available in the 2000s. These lights use a mercury vapor (steam) inside the tube; electricity is applied within the tube, which causes the mercury vapor to emit UV light, or more accurately UV radiation. The UV radiation hits the inside surface of the tube which is coated with a phosphor material. The UV radiation causes the phosphor to glow.
