LED is an acronym that stands for Light Emitting Diode that is a small light bulb, and a LED is different from incandescent light in the following ways: they lack a filament, the have a longer lifespan, and they are more efficient. LEDs do not use filaments that produce heat as well as light thus they are effective since all the electricity that is fed into it is used to emit light thus they use less electricity which leads to lower electricity bills and the last longer (up to 11 years).
There are factors to factor in when selecting a LED sign and one of them is the price. The cost of a LED display is based on the number of LED lights in the sign and the box housing the LED lights and the circuit board that controls the LED lights is not that important when it comes to pricing because it is relatively inexpensive.
It is good to state that LED density is the other good indicator for comparing LED display performance thus the more LEDs per pixel, the higher the brightness and the better the performance and it is a known fact that a low intensity, illegible LED displays will not aid to increase the sales of the business. The number of LED lights per pixel also matter due to degradation and a LED diode will lose close to a fifth of the initial brightness after the first three months of usage after which the brightness of the LED light degrades slowly until it dies at the estimated lifespan of close to 100, 000 hours. Therefore when looking for a LED sign, it is important to note that the manufacturer’s claimed display brightness would decrease by less than a fifth of the initial intensity after two to three months of use.

The other thing to consider is the viewing angle of the of the sign and LEDs can put out a single beam of light like a flashlight, or the potential buyer can put out a wide beam across a room like a light bulb. LEDs put out the same light amount in spite of the type they are, but the ‘wide angle’ LEDs can spread their light across the horizon. It is worth remembering that if the person stands in front of a sign made from ‘high beam’ LEDs with narrow viewing angles, then the person will see an extremely bright LED light. With a wide viewing angle LEDs, the image is visible in consistent brightness, and natural colors throughout the entire range of the display and high quality LED has a 1400 of viewing angle that maintains the best color accuracy and extends the reading times.The Ultimate Guide to Videos
