A LED driver is certainly a worthwhile purchase. Whilst normal transformers do function with LED bulbs, the latter prefer the appropriate driver, and when the right bulb has the right driver, the life span of the bulb is markedly enhanced. So why not treat your LED bulb to an LED driver and keep your bulb beaming?
The relationship between current and voltage dictates one’s need for an LED driver. Current is roughly an exponential function of voltage, meaning in layman’s terms that a small change in voltage produces a large current change. Consequently, voltage that is below the necessary amount, will not produce any current and the LED bulb will not light up. On the other hand, if the voltage is excessive, the current will be forced to go above the maximum threshold, and the bulb will overheat and possibly destruct.
The need for an appropriate power source is thus pivotal when dealing with LED bulbs. As LED’s require constant voltage to function, the source must obviously be a constant-voltage source. The perfect constant-voltage source for the LED bulb is the LED driver, tailored specifically for the needs of the LED bulb. Just as wine tastes better when accompanied by cheese, Torvill ice-skates with greater skill when with Dean, rain is less bothersome when attended to with an umbrella, so too does an LED bulb work better and for longer with an LED driver.
