What Is Lumens In The Projector?
Each projector has a light source, mainly a projector lamp, although other light sources are also used, such as lasers. The powerful bright light of that light source is beamed to produce the projected image on the projector’s LCD or DLP panel. Nothing will show without that light.
Lumens are a measure of a light source’s brightness. It’s the strength of brightness of the projector light in the case of a projector. A projector’s light output is stated in lumens or often as lumens from the ANSI (American National Standards Institute). Remember that for generating the projected image, this light is critical. More lumens will mean a more excellent brightness of the image. It is anticipated that a 4000-lumen projector will be brighter than one of 2500 lumens.
It’s important to remember when you’re shopping for a projector that you can’t just go out and buy a high-lumen device and get excellent image quality. To select a projector brightness for your needs, there is no one size fits all approach & if you want to select a projector for apple products specifically check out the linked guide.
Several variables affect the level of brightness needed for a quality image to be delivered. In this article, we’ve discussed them. The two factors that impact projector brightness requirements are, however, a key takeaway:
- Environmental Light
- Size of Screen
Ambient light is worth discussing on the subject of brightness because it can ruin the image given off by a projector when it is not controlled. Ambient light is light, by definition, that is already present in a scene before adding any additional lighting.
Natural light coming in through the windows, or standard room lights, are the most common example of this.
To deliver quality images, spaces with lots of lighting need more excellent brightness. You can use a lower brightness in a darker space, combined with a higher contrast ratio. For multi-purpose spaces, the ideal lumen range is 2000 to 4000 lumens.
The larger you want, the more excellent brightness is suggested for the projector to move to the topic of screen size to deliver quality images.
Projectors At Home
You want to make sure that you choose a projector in a home environment rated at less than 3000 ANSI lumens. This is enough to project an 80″ image with minimal distortion easily. However, it is worth noting that significant effort must be put into controlling the levels of ambient light with these projectors.
Then you need a projector with a higher lumen count if you are looking to project large images. Although they are more costly, ambient light affects the imagery less.
ANSI Lumens Under 3000
Projecting an 80″ + screen size is comfortable. Usually, people who choose projectors at this level of brightness aim for better color performance. On the other hand, while projecting, they need to control tightly and reduce ambient light.
3000 ANSI Lumens Above
Again, an 80″+ screen is easy to produce, but the quality of the image is less sensitive to the impact of ambient light.”
We’re not saying which level of brightness is better for these two. It depends on the needs of different users. Both can easily project 80″+ screens and the projector with 3000+ lumens is not always more costly.”
For my projector, how many lumens will I need?
If every presentation environment were the same, we would all need our projectors to have the same lumens. That’s hardly the case, however. Presentation environments differ. One aspect of that distinction, so critical to the brightness of the projector image, is the presence of ambient light or otherwise. Ambient light is light, whether natural light enters the room or is-shaped lights present in the presentation space.
What primarily defines the number of lumens you need for your projector is ambient light. Screen size and throw ratio are essential as well. Larger screens require higher lumens for the image’s sharp display, but the critical factor is ambient light.
The point is that the more light in the presentation space is present, the lower the image contrast and the more the image is washed out. Ambient light will undoubtedly reduce the image’s quality, but higher lumens will work to decrease its impact. You need more projector lumens if there is more ambient light.
Against that backdrop, we can classify presentation environments in the following categories of brightness for this purpose:
Dark atmosphere: the lights are off.
Dimly lit environment – lights are dimmed.
Moderately lit environment – light is on, but not dazzling.
Well-lit environment – Full light presence
Brightly lit atmosphere: dazzling light
There’s nothing hard and fast here, as this is just an attempt in the presentation environment to classify levels of light presence. Each light level will require a lumen-capable projector that can counter the ambient light present.
We can go further, with these illustrations, to explain this:
Lights Off: This is like in your living room, where, when using your projector, you have control over your lights and can choose to turn them off. That will also apply to a purpose-built home theatre room where lights are turned off to watch movies. The requirement for projector lumens is low in this dark environment and can be anything in the range of 1500 to 2500 lumens.
Dimmed Lights: This applies to rooms in the office, boardrooms, classrooms, or living rooms where the lights are on but dimmed. For such minimal light presence, projector brightness of 3000 to 3500 lumens will generally be considered adequate.
Moderate Lighting: This would be the case in a relatively large space as some churches, halls, and auditoriums with significant light presence but not dazzling light. Here, 4000 to 5000 lumens of higher brightness will be required. If it can be afforded, anything higher will be added advantage—well-lit large venues with higher ambient light: Like more significant churches, larger halls, etc. The brightness of 5000 to 7000 should be considered when sourcing. Other brightly lit venues: Say stadiums, depending on what can be provided, they will need much higher brightness, even up to 20,000 lumens.
For Smaller Settings, Suggested Lumen Counts
To begin with, 3000-3999 ANSI lumens are ideal for smaller settings, such as a meeting room or classroom. This setting easily projects, at a value price point, an 80″ + screen size.” It is best to use projectors with these lumen levels only when ambient light is minimal.
For Mid-sized Spaces, Suggested Lumen Counts
Then you’ll want to explore buying a projector that is 4000-4999 ANSI lumens if you’re in a mid-sized meeting room or classroom. “This also provides 80″+ high-quality images, but the higher brightness means the user does not have to worry about ambient light as much.
For Large Settings, Suggested Lumen Counts
The final level of brightness to be noted is 5000+ ANSI lumens. This gives an image size of 100”+, making it ideal for large meeting rooms, exhibition halls, auditoriums, and more. Even with high levels of ambient light, the power of these projectors means they work well.
