LED walls are increasingly being used in HoW worldwide as prices become more affordable. Once considered a tool for only the largest mega-churches with budgets to purchase them and the staff to operate them, LED walls are now within reach of smaller organizations with more mainstream budgets. Here we discuss three important aspects to consider before purchasing an LED wall.
The color emanating directly from an LED is very vivid, and very high in contrast – many will say that content on an LED Video wall “really pops.” LED video walls have no problem competing with ambient room light, and they also coexist quite well with theatrical lighting.
Depending on the pixel pitch chosen, a single cabinet can have over 16,000 3-color LEDs. While conversion from Nits (the measure of light output often used for LED walls) to Lumens (the measure of reflected light used for projection) is not a direct process, since one involves area and another does not, even a modest 1200 Nit LED wall is significantly brighter than most single projectors are capable of. This is why in high ambient light situations, projectors are often “stacked” – two devices sending the same image to the same screen to meet minimum brightness requirements for the venue. By comparison, a 1200 Nit LED wall would actually be too bright in some more theatrical-style church lighting situations.
