That's fantastic! HDR TV works best with high nit counts and generally requires a minimum of 500, with a lot of models aiming for at least 700. Lumens = {Lux * Area} / {Screen Gain} ANSI Lumen is the Acronym for American National Standards Institute, ANSI has established the standards for measuring lumen brightness of projectors. However, a commercial grade monitor is much higher.

Always make sure to keep this in mind when deciding how to run your digital display! These two terms are the way in which people refer to how bright the image will appear based on the device they are using. Want to measure the lumens on Earth given off as a direct result of the moon.

As long as you don’t max out your brightness when you don’t need to, it won’t have any negative effect on your battery. A theater projector is probably emitting more total light (measured in lumens) than any smartphone, but the phone packs more light into a smaller space. When  it comes to digital display technology, not all devices are created equally. A single nit actually gives off more light than a single lumen, and is equal to about 3.424 ANSI lumens. That would a fraction of the moon's lumens, but still quite a bit.

A standard home TV will put out roughly 100-200 nits. Check out our comment policy here. If you plan on running a display in a location with a high amount of ambient light, a high-bright monitor may be your only realistic option.

Nits are important but shouldn’t be the one deciding factor in your screen choice unless you specifically need something above a certain level of brightness for HDR or outdoor use. Note that these metrics are designed to measure the perceived brightness of the human visual system and may not be appropriate for non-visible light, for example. Technically, a device starts counting as “sunlight-readable” when it hits at least 1,000 nits, but very few mobile displays go that high. 200 is on the low end but still usable, while above 400 is above average. Lumens are simply the amount of light emitted per second by a projector.

For example, if I was to put the light meter right onto a display and set the display’s brightness to 500 NIT (emitted), I would get a reading of ~500 LUX (received) on the light meter. The initial light energy is spread to an ever-larger area and becomes dimmer. This will be represented on a surface-per-unit area basis, and the standard measurement of luminous output is one candela per square meter (cd/m2). The effectiveness of a TV or projector usually comes down to the quality of the picture being presented. In the context of this site, we mention LUX (Wikipedia page) as the brightness as measured by a light meter. ). Unless that device happens to be an HDR (High Dynamic Range) TV, that is. For instance, if we say that it is a photo that was shot at 0.5 LUX, it means that we measured 0.5 LUX right where the subject was. Higher quality projectors can use (in some cases) over 6,000 lumens. If you managed to get 400 candles/nits into the cube before it burst into flames, the light per square meter would be 400 nits, which makes for a pretty nice laptop screen.

NIT is a metric for measuring luminance, which is how much light an object emits.

That’s right – candles are still the base unit of light measurement, and if you’re screen-shopping, you’ll probably come across the “nit” unit, which tells you how much candlelight per square meter your screen can emit. The most important thing is just knowing what a low, medium, and high nit number looks like for a given device so you can make an informed decision. © 2006-2020, SSIDisplays, aka Screen Solutions International. Quantity : Unit : is equal to : Conversion Factor : Reference Unit : 1: apostilb = 0.31830988618379: nit: 1: blondel = 0.31830988618379: 1: bril = 3.1830988618379E-8 Standard models regularly put out 400 nits, and a high-bright monitor can put out anywhere between 2000 to 2500 nits! Today, we have a much more scientific and complex definitions of a Candell, but for a basic understanding, the description above is sufficient. Since they’re commonly used outdoors, smartphones are definitely in the “more nits are better” category.

Avec l'apparition des diodes électroluminescentes, une autre unité de mesure est employée, le lumen. On the other hand, if your device never leaves the basement, you probably aren’t turning up the brightness all the way anyway, so having more nits wouldn’t help much. When you are talking about lumens, you are describing the amount of light output in ANSI (America National Standards Institute) lumens. In other words, a projector has to have roughly three times as many lumens as a TV has nits in order to give off the same amount of light. NIT and cd/m2 represent the same thing and can be used interchangeably, although it’s better to be consistent. If you skipped down to the end of that hoping to find the super-simple summary, here it is: If you’ve ever tried using a dim device on a sunny day, you’ll understand why nits matter. If you want to dig, check the Lumen page of Wikipedia. Most light meters you can buy have a ~0.8-inch hemispherical light sensor and have a range of 0.1 to 200,000 for the basic models.

Movie theater screens, which are exclusively used in dark environments, are usually around 50 nits, while smartphones, which get a lot of outdoor use, tend to be at least three or four hundred. Laptops and PCs are mostly indoor creatures, so they don’t need to be as bright.

If I was to move the light sensor farther away, the incoming light energy would diminish because the emitted light would disperse over a larger area, and less of it would hit the sensor. All the light hitting the walls of the cube equals “one nit,” which is technically defined as “one candela per square meter.” Every additional candle you add to the cube will add another candela of luminosity, and, therefore, another nit, since the square meter now has more light in it. The Lumen is defined from the Candella, a topic that we covered for the first 1000 NITs smartphone, the LG G7. Resolution, contrast ratios, black levels, sRGB color, and other factors also affect your screen quality, and as long as you’re not on the far low end of the nit range, you’re probably fine. NIT is equivalent to Candela (cd/m2), but is not part of the International System of Units (abbreviated SI, from Systeme International, in French). Candelas, Nits, and Lumens 101. Namun, untuk konsumen yang membandingkan TV dengan proyektor video, satu cara untuk mengatakannya adalah 1 Nit sebagai perkiraan setara dengan 3, 426 ANSI Lumens. A Sony prototype HDR TV was able to hit 10,000 nits, though most HDRs max out around 2,000. As a general rule, anything above 400 to 500 nits will do pretty well on a sunny day, but at 200 nits, you might have to find some shade to answer texts. These two terms are the way in which people refer to how bright the image will appear based on the device they are using. This is why light becomes dimmer as you measure it farther away from the light source.
