LED poster brightness guide
Brightness is measured in nits (candelas per square meter). Our indoor LED posters start at 500 nit, which is set for normal indoor lighting. The outdoor poster starts at 4500 nit, about nine times as bright, so it can be read in daylight. This guide explains which one fits where.
- From 500 nit
- From 4500 nit outdoor

Direct sun lowers contrast
As with any LED screen, direct sun on the front lowers contrast. Place the poster out of direct sunlight where you can choose the position. Face an outdoor poster away from the low sun.
Behind a store window
An indoor poster behind glass works, but direct sun on the screen lowers contrast, and glass can reflect lights and windows. If the window gets direct sun, look at the outdoor poster: it starts at 4500 nit. In ordinary indoor light that much brightness is not needed and the indoor poster is the better fit.
Acrylic glass and reflections
A glass front, such as the LED poster with acrylic glass screen, can show reflections of windows and lights. Place the poster away from direct light behind the viewer and test your content.
Dimming and scheduling
On the outdoor poster the player schedules brightness by time of day: bright in daylight, lower in the evening to avoid glare and cut consumption.
Choose with a test
Brightness needs depend on the place. Tell us the position (window, entrance, hall) and the time of day it is seen, and we advise.
Questions and answers
What is a nit?
A unit of brightness, one candela per square meter.
Is 500 nit enough indoors?
It is set for normal indoor lighting. In a bright lobby with windows, check your position with a test.
Can I use an indoor poster by a window?
Yes, if the sun does not shine straight on the screen. Direct sun lowers contrast.
When should I choose the outdoor poster?
When the screen sees daylight or direct sun: a storefront, an entrance, an outdoor event.
Can I use the outdoor poster indoors?
Yes, if you need the brightness, for example in a sunny window. In ordinary indoor light the indoor poster is the better fit.
Can I dim the poster?
On the outdoor poster the player schedules brightness by time of day. Ask us about the indoor setup for your control system.
Does brightness change the viewing distance?
No. The viewing distance is set by the pixel pitch.
Will the screen look different through a phone camera?
It can. Refresh rate and shutter speed matter; test with your own phone.
