What hinders the long service life of led lights?

Almost all of the leading brands offer some type of warranty, some as much as a 10 year limited warranty. That's why you have to make sure products like Solar led street lights you're investing in has a reasonable warranty period. A good quality LED bulb can last for 20 years. LED lights are always boasted about for their long lifespan. However, the only hurdle which obstructs the long lifespan of the highly efficient LED lights is their burning out. Solar led street lights might blow off in just six months due to its burning out. There are many reasons for the burning out of these lights. 

The major reason that an LED fails and burs out is excessive heat. However, these illuminations can withstand only a specific heat threshold so that they can maintain a long lifespan.

Another reason why these illuminations fail early is due to LED overdriving. Led lights manufacturers can remind customers to use these lights scientificly. The principle of 'more is less' and 'less is more' is applied here. By increasing the power supplied to the LEDs slightly, the amount of light emitted can be increased. 

Moreover, different types of LEDs come with a different heat threshold limit. A large amount of their failures occur during voltage spikes, which increases the amount of voltage supplied to the illuminations. Hence, the power cannot be simply turned up for the sake of improving the brightness of these products. For producing brighter products, LEDs are designed around a brighter base. Apt power supplies are used which can drive them to their optimum potential. However, in spite of this fact, they are being pushed towards the brink of their maximum power supply, in view of making them exceptionally bright.
