Q:Brightness is not the only standard. How can I buy projection light bulb?

Bulb, as the only consumable material of projector, is an important factor that must be taken into consideration when choosing projectors. At present, projectors are generally used metal halogen lamps, UHE bulbs, UHP bulbs, these three light sources. The metal halogen bulb has the advantage of being cheap, and the drawback is that the half-life is short, and the brightness is reduced to about half of the total time it takes about 1000 hours. And because of high heat, the projector cooling system requirements, it is not suitable for a long time (more than 4 hours) projection use. The advantage of the UHE bulb is its moderate price and the brightness does not decay almost 4000 hours before use. Due to low power consumption, it is customarily referred to as a cold light source. UHE bulb is an ideal light source widely used in mid-range projectors. The UHP bulb has the advantage of long service life, and can normally be used for more than 4000 hours, and the brightness attenuation is very small. UHP bulb is also an ideal cold light source, but because of its high price, it is generally used in overhead projector.
