Must know the projector's use and maintenance costs
Anyone who knows a little about the projector knows that the lamp is the biggest consumable used by the projector. The typical life span is between 3000-5000 hours, but this does not mean that the bulb will suddenly go out at 5000 hours. Generally, when the life of the light source reaches about 2000 hours, there will be brightness attenuation, and when to replace it depends on the situation.
Everyone's 1-2k bulbs are not affordable for everyone
Some people may say that it is not enough to buy LED light sources? But there are two biggest problems with LED light sources so far, low brightness and high price. At present, the brightness of models using LED light sources is only about 200 lumens on average, and the highest does not exceed 1000 lumens. In addition to ultra-portable entertainment models, the price is mostly unattainable, and there are even promotional activities to buy LED projectors to send to TV. Therefore, we also need to pay attention to the cost of subsequent maintenance.
