Without a quality LED driver in your electronic product, you risk the product burning out prematurely. Not only is this bad for business since no one wants to spend their hard-earned money on a product that won't last long, but it is also a safety hazard because of the risk of the component catching fire when it gets overheated.
A quality LED driver can also help to prevent the electronic device from consuming an unusually large amount of energy because of unregulated power consumption by the LED. The reason why these drivers can help to conserve electricity is because an LED is a power-driven component in which the brightness of the LED is directly controlled by the amount of power supplied to the LED. Without regulation, the LED becomes something akin to a power-sucking vacuum that will pull power without limit.
Overall, you have to choose an LED driver that offers the functionality you need for your electronic devices without having to spend too much on the drivers. Consumers want the most bang for their buck, so you have to come to a suitable compromise between cost and quality according to the needs of your customer base and the desire you have regarding the longevity of use for the products.
