The biggest drawback of incandescent lamps is their short lifespan, which is generally between 3000 and 4000 hours of use. Some low-quality incandescent lamps can only be used for 1500 hours. Incandescent lamps are often used in spaces such as restaurants and bedrooms in homes, and their colors look more comfortable.

Energy saving lamps

Energy saving lamps are popular because of their energy efficiency. A 9-watt energy-saving lamp is equivalent to a 40 watt incandescent lamp. The lifespan of energy-saving lamps is also relatively long, generally ranging from 8000 to 10000 hours. After using energy-saving lamps normally for a period of time, the lamps will become dim, mainly due to the loss of fluorescent powder, which is technically known as light attenuation. Some high-quality energy-saving lamps have invented constant brightness technology, which can keep the lamp tube in optimal working condition for a long time. After 2000 hours of use, the light attenuation is less than 10%.

Metal halogen lamp

Metal halogen lamps are actually a type of incandescent lamps, with a lifespan generally between 3000 to 4000 hours and not exceeding 6000 hours. This type of lamp can be used for key lighting, such as highlighting decorative paintings on walls, indoor decorations, etc. It can be illuminated with a cold light lamp cup, and the white light of the lamp can change according to different home decoration styles, keeping in line with fashion.
