Projector bulb type

Commonly used projectors are metal halide bulbs, UHE bulbs, and UHP bulbs. Metal halide bulbs have the advantage of being cheap and have the disadvantage of having a short half-life. Generally, the brightness is reduced to about half of the original in about 1000 hours. And due to high heat, the projector cooling system requires high, not suitable for long (4 hours) projection. The advantage of UHE bulbs is that they are affordable, with little degradation in brightness before 4000 hours of use. Due to low power consumption, it is customarily called a cold Light Source. UHE bulbs are the ideal light source widely used in mid-range projectors. UHP bulbs have the advantage of long service life, can generally use 4000 hours or more, and the brightness decay is very small. UHP bulbs are also an ideal cold light source, but they are generally used in high-end projectors due to their high price. It is recommended to purchase projectors that use UHE, UHP cold light source, which will effectively protect your projector's use and save your investment. In addition, special attention should be paid to: the bulbs used by different brands of projectors are generally not interchangeable, so the purchase of projectors should be chosen to purchase well-known brand projectors sold by well-known domestic companies, so as to avoid the purchase of a suitable lamp after the lamp is used up. The lamp causes the projector to be scrapped.
