WHAT ARE CANDLES OR NITS?

Candle per square meter (cd / m²) is the International System of Units’ photometric unit of luminance and is used as a measure of the light emitted in an area of ​​1m2. This unit is used to specify the brightness that a LED screen emits at its maximum power and in white color (keep in mind that this unit is also known by the name of nit).

THE IMPORTANCE OF LUMINANCE OR BRIGHTNESS ON LED SCREENS

The brightness levels on LED screens allow to create screens in places exposed to full light without losing content visibility Thanks to this, giant LED screens have become one of the most demanded advertising elements in the outdoor advertising sector.

 

Let’s see a comparison of the brightness of led advertising screens compared to other systems:

WHAT LUMINOSITY SHOULD MY LED SCREEN HAVE?

As a rule, for outdoor screens, it is advisable to use a brightness higher than 6,000 nits. (We understand outdoor screens as screens resistant to rain and exposed on poles or facades of buildings, where the sun strikes directly).

For LED screens in shop windows oriented towards the outside, luminosities of between 1,500-3000 nits are advised. But if the sun strikes directly and constantly in the shop window throughout the day, it is advisable to have luminosities greater than 5,000 nits.

Regarding the protection against rain, apart from the fact that the price of the screen is usually much higher, the reality is that the brightness of a screen is totally independent from its environmental protection.
