What happens if a 5volt LED chipset is connected to a lower or higher voltage power supply?

What happens if the voltage supplied to a Light Emitting Diode ("LED") is over or under rated?
(i.e. incompatible power supply)

Generally in the market, LEDs are using either 2.8-3.2volt, 12volt, 24-36volt forward. What does that mean?

Simply, it is the required voltage from the power supply to make the LEDs work. 

If the voltage supplied is under the LEDs requirement;

1. The LEDs may not light up
2. The LEDs may light up, albeit at a lower brightness or effectiveness as compared to its maximum potential.

If the voltage supplied is over/above the LED requirement;

1. The LEDs may be overcharged and light up brighter than its usual or standard light output.
2. This will reduce the lifespan of the LEDs dramatically, resulting in the LEDs melting or failing quickly. *Do take note not to super charged LEDs without any expertise supervision as it may cause hurt or fire hazard.

So whats the importance of the forward voltage? Shouldn't we be concerned with just the current supplied to the LEDs?

Please refer to the graph below;
This is a common current to voltage graph of a typical LED diode.

LED World Magazine: Impact on Business with Spoilt LEDs

Once again we have been featured in the LED world magazine. 

We are honoured to be invited as a LED lighting specialist to be featured on the LED world magazine with our insights on the industry. Kindly refer to page 60 for our opinion relating on how the low barriers of entry in selling LED lighting changes the user experience. *The article had been contributed out of goodwill and is published at the authors sole discretion without having any monetary or material benefits for any other parties.

Do refer to page 26 to 32 where LED lighting is being gradually implemented in Vatican, Sistine Chapel. While the pictures are amazing, it is yet another testament to the benefits of LED lighting on existing paintings and displays.
