How to Choose A Projector For Bright Spaces

 

 A projector can be a great addition to any office or home. It allows office goers to hold presentations in an attention-grabbing manner and exhibit proposals and reports to their clients and peers immaculately. Homeowners can have an immersive entertainment experience by installing a projector along with their home theatre. Even establishments like restaurants, pubs, and bars can enthrall their customers by using projectors for displaying sports, songs, and movies. 

 Projectors are available from different brands and come in models with varying features. The right projector for a room will depend on the ambiance of the room as well as the requirements of the buyer. While the best environment for installing and using a projector is a room with low ambiance lighting, it may not always be feasible.

 Meeting rooms in offices and living roomsat homes may have transparent windows that allow sunlight to enter the room. Sometimes, the place where the projector is being used may not have the capability to dim the lights selectively or curtains for blocking outside light. Not every projector will function well in a bright space.The bright ambiance lighting of the room will decrease the visibility of the projector making it harder for the viewers. While people can’t control the environment they are going to install the projector in; they can opt for a projector that is more suitable for it.

There are a few considerations that can help buyers to choose the right projector for bright spaces.

Lumens Rating

The lumens rating of a projector is the primary factor to consider while choosing a projector for bright spaces. The lens of a projector emits light for displaying images. The brightness of the light emitted will depend on the lumens rating of the projector.The lumens rating of projectors varies from model to model. It can be as low as 200 lumens on compact and portable projectors and as high as 6000 lumens on top-end projectors. The higher is the lumens rating of a projector the brighter is its output.

Projectors have two brightness ratings.

White Brightness – The white brightness of the projector is expressed in lumens and specifies the amount of white light the projector emits. 

Color Brightness – The color brightness of the projector is expressed in lumens and specifies the color light output of the projector.

Buyers who are looking for projectors for bright spaces must consider models with high white and color brightness.It is because the light output by the projector competes with the light from other sources. The brighter is the light emitted by the projector, the more visible it will be. For darker and low light rooms, projectors with low lumens rating are sufficient. Rooms that have plenty of natural light should be installed with projectors with high lumens rating. Homeowners or venues that use projectors in low to moderate ambient light should not buy a projector with a very high color brightness as the images produced by these projectors might have washed colors.

 

 There are dual lamp projectors are also available from some manufacturers. They have even higher lumens rating and can yield steady performance over a long duration. The dual lamp projectors are a great choice for scenarios where image brightness is a top priority and there is high ambient lighting.

Distance from the Screen

Another important factor to consider while choosing a projector for bright spaces is its distance from the screen. The image the projector produces will be brighter when it is installed close to the screen and will be duller when it is comparatively farther away from the screen. A projector farther away from the screen will require a higher lumens rating than a projector which is closer to the screen.

The throw ratio of a projector denotes the width of the image output by the projector when it is at a specific distance from the screen. Buyers can consider buying projectors that have short throw ratio if the location permits. A short throw projector rated at 3000 lumens might produce a brighter image than a 4000 lumens projector that is farther away from the screen.The projectors with short throw ratio will be closer to the screen and produce abrighter image then projectors with a normal or large throw ratio having the same lumens rating and producing equal sized images.

 

Size of the Room and the Audiencen

People use projectors for different purposes. Some may install a projector for showing a presentation to a small group of people in office while others may use it to address a large audience in a hall. The lumens rating of a projector which will be used in a small-sized office can be less while the lumens rating of a projector in a large-sized conference hall will have to be much higher.

It is because the people in a small room will be closer to the projector screen and it will be easier for them to see the image. In a large audience, some people will be seated farther away from the projector and it will be harder for them to see the projector.The light will also disperse more in the large environment. Therefore, the size of the room must be considered while choosing a projector for bright spaces. If the projector is going to be used outdoors, there are specific models available from renowned brands which the buyers can consider.

Contrast Ratio

The contrast ratio of a projector is another important feature to consider when choosing a projector for bright spaces.The images output by the projectors are composed of pixels which are the smallest component of the image. The number of pixels depend on the resolution of the projector. Contrast ratio denotes the difference between the brightest and the darkest pixel that the projector can display. It adds depth and dimension to the images.

Ambient light reduces the perceived contrast of projectors. Users who want a projector for bright spaces must choose one that has the highest contrast ratio. Manufacturers specify ANSI contrast and dynamic contrast ratios on their projectors. Dynamic ratios are generally higher but are not ideal for comparing projectors. It is because the dynamic ratio is measured between two images, one of which is white and the other is black. ANSI contrast ratio is measured from a single image having black and white square patterns. Users must consider the ANSI contrast ratio of the projectors.

 

Projector Screen Material

The projector screen being used also impacts the quality of the output image. Some screens reflect the light from a projector better than others depending on the material used in their construction. There are projector screens available which have high reflection capability and can improve the contrast ratio of the projected images significantly. A high contrast ratio makes it easy to distinguish between light and dark colored elements in the image especially in bright spaces. It can be beneficial in presentations that use texts as it makes the dark text stand out against the light background and improves visibility.

The reflection capability of projector screens is denoted as screen gain. The higher the screen gain value of the screen, the better it will perform in bright spaces. A black border around the screen also increases the perceived contrast. Individuals who already own a projector that is being used in a brightly lit environment and can’t replace it with a new one can opt for a high-quality projector screen. A screen is also going to be always better than a wall in bright areas.

DLP vs LED vs Laser Projectors

Projectors use different types of technologies to project the image. The Digital Light Processing (DLP) projectors use micro-sized mirrors and produce sharp and bright images. Some projectors use Light Emitting Diodes (LEDs) for delivering images. DLP projectors have better brightness as compared to LED projectors and are more suitable for bright spaces. However, the lifespan of the DLP projectors is less as compared to the LED projectors. DLP projectors are ideal for spaces with high amounts of ambient lighting while LED projectors are more suitable for low and medium light environment. In recent times many companies have also started manufacturing laser projectors. These projectors use focused laser beams to produce images. They also have high brightness, better contrast ratio, and long life but are very expensive. Individuals or entities who can spare the budget should opt for laser projectors.

 Besides these, there are other features that must also be considered while choosing a projector. These include the screen resolution, zoom capability and supported I/O ports among others.

While shopping for a projector for bright spaces, it is best to browse different models available from various brands and ask for a demonstration from their sales teams. Actual visualization of the image produced by the projector can make it easier to choose the right model instead of just looking at their specs.
