Assuming you're talking about the ones with coiled tubes, they're called "compact fluorescent".
They are known as CFL bulbs. It stands for Compact Fluorescent Lamps.
Heat bulbs would be a more appropriate name because incandescent bulbs transform 90% of electricity received into heat and 10% into light. New Compact Fluorescent light bulbs use only 20% to 30% of the energy needed to power a standard bulb for the same wattage.
why light bulbs are fragile
Light bulbs emit light.
EcoSmart, ArmorLite, Philips, GE, and Sylvania all make a line of energy saving light bulbs. They all manufacture LEDs, CFLs, and halogen bulbs. All of these bulbs are comparable in performance and all of these products are energy savers.
Incandescent bulbs.
They are known as CFL bulbs. It stands for Compact Fluorescent Lamps.
Light bulbs can be called heat bulbs because they emit heat as a byproduct of producing light. Incandescent light bulbs, in particular, generate a significant amount of heat as a result of the electrical current passing through the filament to produce light. This heat can be used for warming small spaces or as a secondary function in addition to providing illumination.
Bulbs light up when an electric current passes through the filament, which heats up and emits light. This process is called incandescence.
They are called CFL light bulbs. CFL stands for Compact Fluorescent Light .
Headlight bulbs, high and low beam, parking light bulbs, signal light bulbs, brake light bulbs, dash light bulbs, interior light bulbs, plate light bulbs, etc.
Fluorescent light bulbs produce light by converting ultraviolet radiation into visible light through a process called fluorescence. Incandescent light bulbs, on the other hand, produce light by heating a filament until it glows. The main difference in fluorescence between the two types of bulbs is the method by which they generate light.
Those are usually called "lamps" or "light bulbs".
Incandescent light bulbs and halogen light bulbs are examples of light bulbs that produce heat.
