![]() The American National Standards Institute ( ANSI) defines a unit of measurement, ANSI lumens, to gauge the total amount of light emitted by a projector. Some companies advertise their projector’s lumen output as being higher than it actually is to mislead customers into thinking their product is brighter than it really is.įor example, they may say a budget projector has 2500 lumens when the truth is that the device only emits 750 lumens of light. On average, just 30% of a lamp’s output is projected onto your screen. In reality, by the time the light reaches your screen, its intensity has diminished significantly. Though a projector’s lumen rating speaks to the brightness of its light source, that number only tells half the story. Consequently, if you need the projector for a large space like an auditorium or lecture hall, it’s best to get one with 3000-4000 lumens (or even more). If the environment will be brighter, like in a classroom or conference room with windows, 2000-2500 lumens is what you’ll need. ![]() If you plan to use your home theater projector in a dim room, look for one that emits at least 1000-1500 lumens. The more lumens, the brighter your projector will be. The brightness of your projector is determined by the lumens. The actual color brightness is often only a third of the lumens indicated □ ![]() The lumen rating mostly refers to the projector’s white brightness. When you’re out shopping for a projector, always be on the lookout for two lumen specifications: one for color brightness and another for white brightness.ĭifferent projectors and brands can hugely vary in their output, so make sure to measure and list colors separately to give yourself an accurate idea of what you’re working with. The projector’s lumen rating will be higher if it is brighter, and usually also means that the projector will cost more. Projectors are available in a wide range of brightness, which is measured in lumens. But in general, most people agree that 2000-4000 lumens is a good range to aim for. So if you’re wondering what is a good lumens for a projector, the answer is that it depends on your needs. It also has excellent image quality, making it a great option for presentations or movies. It has 4000 lumens, making it a great choice for bright rooms or daylight projection. If you’re looking for a high-quality projector with a bright output, check out the Optoma HZ39HDR. But now that you know what lumens are and how many you need, you can make an informed decision about which projector is right for your needs. Of course, the final decision is up to you. If you’re projecting in a very bright room or you want to be able to see your projection even if there’s some ambient light, you’ll need more like 3000-4000 lumens. ![]() In general, though, most people agree that a projector needs at least 2000 lumens to be effective. If you’re going to be projecting in a dark room, you won’t need as many lumens as if you’re trying to project in a brightly lit room. It depends on a few factors, such as the ambient light in the room and what type of content you’ll be projecting. This is because LEDs have improved color saturation and luminous efficiency, appearing to be brighter than their ANSI lumen measurement suggests. Even though LED projectors typically only emit 2000 lumens, they deliver a higher-quality image than lamp projectors. Usually, lamp projectors need at least 2000 lumens to run properly, while laser projectors can provide more than 3500 lumens with optional equipment.Ģ. LED, laser, and lamp are the three key light sources in projector technology.ġ. The following are approximate lumen counts of common light sources: The more lumens, the brighter the projector will be. Lumens measure the amount of light that a projector is able to produce. Other Factors that Affect Image Quality.How many Lumens is Good for a Projector.But what exactly are lumens? And how many do you need for your particular situation? If you’re looking for a projector, one of the things you’ll want to pay attention to is the lumens.
