Projectors have recently become the preferred choice for people who want to
experience the thrill offered by the huge projector screens of cinema in
their living rooms. Besides being used as home theater projector,
projectors are also extremely useful in office presentations where you want
to connect with a large group of audience.
However, with plenty of types and brands of projectors to choose from, you
can easily get confused and might even end up spending precious money on a
device that is not meant for the desired use. It is, therefore, highly
recommended to research the various available options and understand their
features like lumens, contrast ratio and resolution etc.
What is projector ANSI lumens and what does ANSI mean?
The brightness of a projector is measured in ANSI (American National
Standards Institute) lumens or just lumens. The higher the projector lumens
rating, the brighter the light wave intensity will be and the brighter the
Although lumens is not directly related to the size of the projected image,
a larger image will need to be brighter because the projector needs to be
further away from the screen and will need more lumens. The projectors
available nowadays generally range between 500 and 10,000 lumens.
If there is ambient light in a room, owning a projector with more lumens
will make the image more defined. Light in a theater room will make an
image with 1000 ANSI lumens seem washed out and harder to see. In the same
room with the same amount of light, a projector with 1800 ANSI lumens will
be much easier to see.
It is important to make sure that the projector lumens rating is measured
in ANSI. Some manufacturers use different lumens rating standards just to
make their numbers look higher when they are actually not.
How many lumens do I need?
The number of projector lumens depends on the machine’s intended use. The
higher the lumens, the more the projector tends to cost. Therefore, it is
essential to determine the number of projector lumens you require to avoid
a situation where you end up wasting precious money because you bought an
expensive projector with way too many lumens.
Here are some things to consider while determining how many ANSI lumens you
What is the intended use of the projector? : If the device is going to be used as a home theater projector in a
blacked out cinema room with no light, find a projector with at least 800
ANSI lumens. Owning a projector with more than 1200 ANSI lumens would be a
waste of money (assuming your paying more for the lumens). If the room is
sufficiently darkened but has a little bit of ambient light, a projector
with 1500 lumens is enough to cast a bright image.
If the projector is expected to be used for multiple purposes, then
consider the lighting conditions. If you plan on using the projector
outside, find a projector with at least 3500 lumens and use a darker
projector screen like a black diamond screen or a silver screen.
The size of the group of audience and throw : If the projector will be used for large audiences which require a larger
screen, the projector may need more throw (the distance between the
projector and the screen) and will need more lumens. For throw distances
over 22 feet in a dark theater, you will need a projector with at least
The amount of light entering the room : A completely blackened out room will require 800 lumens, a bright room
with windows and lighting will need at least 3500 lumens and a recommended
The type of screen : There are several types of screens that can produce a bright image. In a
blacked out theater setting, a white screen with a grain is perfect and
will always reflect a bright, clear image without losing contrast. In a
room with ambient light, the blacks will seem grey unless your using a
darker screen, for example a silver screen or a black diamond screen will
make the blacks look darker and delivering a better contrast ratio. If you
plan on owning a darker screen, the darker material may make the image seem
dimmer unless using a projector with at least 1500 lumens.
Now you know! More ANSI lumens isn’t always better so please don’t waste
your money. Always make sure you have enough, especially if you have
windows or constant lighting. For more information about projectors or to
