Projector purchase guide, do not look at the parameters to see the light source, choose LED or laser

At present, with the development of projector light sources, we have experienced three major categories: bulbs, LEDs, and lasers. Among them, the light bulb machine was widely used in the early years because of its short life, expensive follow-up maintenance, mediocre display effect, and many unstable factors. Later, it was gradually replaced by LED light sources. Of course, there are still some brands that use bulb light sources, but most of the projectors with bulb light sources are commercial and office-based, and relatively few for home use.
