What do lumens mean in projectors




















In fact, the difference might not even be noticeable, although the difference between a 2, and a 3, lumen projector would be. Manufacturers rate projectors on the basis of their maximum light output, but most projection modes actually reduce the amount of lumens the projector produces.

To get as much brightness as possible out of your projector, turn off the lamp's eco mode, which cuts brightness to save power and extend the lamp's life. Go into the projector's image menu options and look for bright, vivid or conference room modes or something else along those likes.

Natural, cinema and movie modes typically cut light output to increase a projector's performance on the dark scenes that are common in many movies and television shows. In addition to lumens, manufacturers typically rate how different a projector's black looks from its white. The contrast ratio expresses this numerically.

While a higher contrast ratio is better than a lower one, since there's no popular standard for rating contrast, it's possible for a 10,to-1 projector to actually outperform a ,to-1 projector. Given normal business projection conditions and the type of material that usually gets projected, contrast ratios are much less important.

There are many important factors when considering what projector will work best for you, whether you need a projector for home, school, office space, or your church. Simply put, the more lumens your projector can produce, the brighter the image will be and the less you need to worry about whether or not the shades are drawn in your space.

Lumens are the measurement used to measure the brightness of a light from any source, i. The more lumens a light has, the brighter the light is. When it comes to projectors, lumens describe how bright the light coming from the projector lamp is, and how well your image will be displayed on a screen.

The biggest competing factor here is ambient light. Any light from the room you are in will alter the image coming out of the projector. This is why movie theaters are almost pitch black.

To help you understand lumens, here are some approximate examples of lumens in other sources:. Lumens are a very important factor in buying a projector. Brighter is not always necessarily better. Again, this will depend largely on your home theater set-up. In a completely dark space, anything rated higher than around 2,, lumens may seem overwhelmingly bright. The most confusing part of projector brightness is not the lumen rating itself but figuring out how accurate the stated rating is.

A model that says it puts out 2, lumens might in reality give you more like 1,, and most users would have no way of knowing. You can get away with using a projector rated for 2,, lumens in a semi-lit environment.

Lower than that, and you may be disappointed by the reality of the picture that you get. The best way to get a true understanding of lumens, though, is to see them in action. Having a visual in mind will make the numerical rating a lot easier to interpret—especially since you can trust your eyes more readily than you can the numbers.
