Are Lumens Important?

Are Lumens Important?

Are Lumens Important? The short answer is yes.

In fact, lumens are pretty important. Whether you need a projector for your home, office or school, there are many factors that should be considered before purchasing a projector; one of the main factors being lumens.

Projector lumens will always be listed in the projector specs, and to put things simply, the more lumens a projector produces, the brighter the image will be. It also means that the days of making a classroom or office pitch black before starting a projector are long gone, as the projector should be bright enough to project a perfect image in daylight.

What are Lumens?

Lumens are a way to measure brightness from light sources, so the more lumens a projector has, the brighter the light is. To help you better understand, below are some rough examples of lumens in other light sources:

  1. Candles – 13 lumens
  2. Average sunset – 400 lumens
  3. Car headlight – 1000 lumens
  4. 100 watt light bulb – 1600 lumens
  5. Projectors – these range from 500 lumens to 10,000 lumens

Do Lumens Matter?

As you can probably tell by now, lumens are one of the most important factors you need to consider before purchasing a projector. The brighter the projector is, the less dark or ambient light will matter with regards to picture quality. It also means you can place the projector as far away from the projector screen as desired.

Here is a rough guide of what can work when you have to choose a projector for different spaces.

  • To use a projector in a living room with the lights off, you would need approximately 1,500 lumens to 2,000 lumens.
  • To use a projector in an office or a small classroom with dimmed lights, you would need approximately 3,000 lumens.  If it’s in a hall or larger area, then a 5/6/7/8k lumens projector could be the best choice.
  • A movie theatre would need massive 20,000 lumens.

If you are unsure of what projector and lumens to choose for your space, it’s a good idea to get a specialist in projector installations to do a thorough site survey to assess the space, perhaps measure it out and to discuss what you need to achieve from your projector. A specialist will look at the full layout, stress test the walls and ceilings and advise on what the best mount, be it wall or ceiling, is best for space.

How Lumens Can Decrease Over Time

For projectors, the light source is within the bulb of the lamp. The bulb is of key importance to the amount of brightness a projector produces, and over time the brightness of the bulb will slowly decline and a replacement bulb can be bought to give the projector its lease of life back.

Rear View Projection

Rear View Projection

Rear View Projection.

Rear projection is a special effect technique that is used in film productions. It is the effect of combining the foreground with an existing background that could be filmed beforehand or painted or computer generated images (CGI). It is commonly used in the film industry, mainly in driving scenes or to show some form of background motions. This effect is to create an illusion that the characters are in a place they are not in, very similar to a blue/green screen effect.

The actors would have to stand in front of a giant screen while a projector is positioned behind it to show an image for the necessary background. The background usually would appear much fainter than the foreground, and it could be a still image or a moving image, but they are both called the “plate” and one might also hear “Roll plate” in a film set where rear projection is used to instruct the crew to begin the projection.

In order for rear projection to work and not showing any faults in the plate, the sound stage camera has to be in perfect synchronization with the projector. Both the camera and the projector have to be operating at 24fps, so that there will be no fringes or any halos appearing in the screen.


The rear projection was mainly used to film actors in driving or any moving vehicle scenes, which is in fact a vehicle prop that is set up in front of the plate. In such cases, the actor would seem very odd compared to the projected background, because the projected background was not shot steadily and the bumping movement of the background was not recreated by the actors.

Digital Strategy For Schools

In October 2015, then Minister Jan O’Sullivan announced the largest ever investment in Digital Strategy For Schools. The Minister for Education and Skills announced a €210m investment in digital technology in schools, the largest ever such investment.

Among the key points of the Digital Strategy For Schools are:

  • Dedicated multi-annual funding to schools to invest in technology.
  • Build on the successful roll-out of high-speed broadband to every second-level school.
  • Develop opportunities for students to take an in-depth ICT (information and communication technology) course at Leaving Cert.
  • Provide enhanced digital content to schools, including working with cultural institutions, sporting bodies and others.
  • Embed ICT skills as part of initial teacher education and ongoing training for teachers.
  • Work to promote safe and responsible use of the internet and social media, including new resources to schools to better prevent cyber-bullying.
The Strategy is the result of extensive national and international research. The Strategy involved extensive consultation and reflects the views of education stakeholders including students. It has been developed around key themes.

Modernising the curriculum, to embed digital learning, will be a very important part of the Strategy. The NCCA  (National Council for Curriculum and Assessment) will ensure that future curriculum specifications will incorporate clear statements of learning that focus on developing digital learning skills and the use of ICT in achieving learning outcomes at all levels of education.

Recognising the importance of progression to further and higher education, the Strategy will support the development of opportunities for learners to undertake in-depth study of ICT in the Senior Cycle. The Strategy will also impact on the continuum of teacher education from initial education through induction and continuing professional development for teachers.

The Strategy sets out a set of actions to be achieved from 2015 to 2020.  The Department of Education and Skills will provide leadership in order to ensure the Strategy is successful and these actions are achieved.
