High-brightness projector buying guide: lumens, light source, ambient light, three factors must be understood

First, do you really need a high brightness projector?

For many first-time projector users, “the higher the resolution, the better the picture quality” seems to be common sense. But in fact, if the projector brightness is not enough, 4K resolution does not help, because the picture will be dull and distorted due to ambient light. Therefore, in the natural light or open light environment, the brightness is the key to determine the practicality of a high brightness projector.

Second, high brightness ≠ false labeling parameters, how to read lumens?

Many projectors on the market labeled 5000 lumens, 7000 lumens, in fact, the “light source brightness” rather than “ANSI lumens”.

ANSI lumens is the international standard, the most truly reflect the high brightness projector in the normal use of the scene under the screen brightness.

Home: 2500-3500 ANSI lumens recommended

Business / Conference Room: 3500-5000 ANSI lumens

Outdoor / large venues: 5000 ANSI lumens or more!

Third, the impact of different light sources on the brightness

At present, there are three common light sources for high-brightness projectors:

LED light source

Advantages: long life, good color, low power consumption

Disadvantages: lower limit brightness, suitable for small and medium-sized space

Laser light source

Advantages: high brightness, wide color gamut, instant brightness, excellent heat dissipation performance

Disadvantages: relatively high price, suitable for high-end home, commercial, exhibition

High-pressure mercury lamp light source

Advantages: the strongest brightness, moderate price

Disadvantages: short bulb life, high maintenance costs, relatively noisy

Fourth, the ambient light and the curtain can not be ignored

Even if the projector brightness is high, if the wall reflectivity is poor or the curtain material is not good, it will weaken the final display effect.

It is recommended to match the gain curtain (such as gray curtain, high gain curtain) to enhance the contrast, so that the picture is still clear in a complex light environment.

V. Real user pain points

Can I watch during the day?

Should I pull the curtains when the light is on?

Will the big picture from a distance be blurred?

Will it overheat and make a lot of noise when watching for a long time?

These are the real concerns of most users after purchase. High brightness projector is not just bright, but also to solve the heat, noise, power consumption and other comprehensive experience.

Sixth, the purchase of tips

Try to offline stores to experience the effect of the actual machine

Check the real ANSI lumens, do not just look at the “light source brightness”

Compare the type of light source of different brands and maintenance costs

Choose a regular brand with perfect after-sales service

High brightness makes high brightness projector work better

From home theater to business presentations, high brightness projector are only qualified to talk about color, resolution and contrast if they are bright enough. We hope that this high brightness projector buying guide will help you find a truly suitable product to create your own clear big screen experience!
