The ideal lumen range for multi-purpose spaces is 2000 to 4000 lumens. In a darker space, you can use a lower brightness, combined with a higher contrast ratio. Spaces with lots of lighting need a higher brightness to deliver quality images. The most common example of this is natural light coming in through the windows, or normal room lights. By definition, ambient light is light that is already present in a scene before any additional lighting is added. On the topic of brightness, ambient light is worth discussing because when it isn’t controlled, it can ruin the image given off by a projector. However, a key takeaway is the two factors that impact projector brightness requirements are: There are a variety of factors that affect the level of brightness needed for delivering a quality picture. There’s no one size fits all approach to choosing a projector brightness for your needs. When you’re shopping for a projector, it’s important to remember that you can’t just go out and purchase a high lumen device and get great picture quality. What Brightness Level Best Suits Your Needs? This is because LED projectors have improved color saturation and luminous efficiency, which allows LED projectors to appear to have a higher perceived brightness than their ANSI lumen measurement than they may actually possess. That being said, LED projectors often max out at 2000 lumens, but unlike lamp projectors, they’re known for delivering higher quality image perception. It’s an extensive topic that we’ve covered in this article, but a few important points to note are that lamp projectors typically run at least 2000 lumens, while laser projectors can easily provide higher than 3500 lumens – often higher with optional equipment. There are three key light sources in the projector realm, those being LED, laser, and lamp. Fluorescent lighting in office – 400 lumens.The Projector Expert reports the following lumen counts of common light sources: In the industry, the formal term is “ANSI lumens.” ANSI being short for American National Standards Institute. Lumens are the measurement of brightness that a projector gives out. So what are lumens? Let’s find out and how they apply to selecting the right digital projector for your needs. While we’ve already discussed projector quality elements such as device resolution, something else to consider is the lumen count of the projector you purchase. When you’re evaluating projectors for your home or business, it’s easy to become overwhelmed with the terminology associated with the devices. So read on to answer the question “What are lumens?” and find the best projector for your needs. (Don’t worry, we provide a quick guide to how many lumens are required for what scenarios below.) In projectors, this relates directly to the environment where the projector will be used. But what are lumens? And why are they important? Officially called ANSI lumens, this measurement shows how strong a light source is. Lumens come up all the time when you’re shopping around for a projector.
