Does dimming an LED bulb extend its life?
While it is true that LEDs are already very efficient compared to almost any other light source, you save even more energy by dimming them. Dimming LEDs also makes them run cooler, extending the life of the electronic components in the driver, as well as the phosphor in the LEDs.
How can you increase the life expectancy of a high power LED?
Give The Lights Ample Cooling Down Period
Just because these bulbs emit lesser heat as compared to incandescent bulbs, doesn’t imply that they don’t need to cool off. In fact, letting these bulbs cool off sufficiently will extend their age and improve their illumination.
How long are LED bulbs supposed to last?
Many LEDs have a rated life of up to 50,000 hours. This is approximately 50 times longer than a typical incandescent, 20-25 times longer than a typical halogen, and 8-10 times longer than a typical CFL. Used 12 hours a day, a 50,000 bulb will last more than 11 years. Used 8 hours a day, it will last 17 years!
Why are my LED bulbs dying so fast?
The most common reasons for LED blowing out are high voltage, bad contacts, use of incompatible dimmer switch, or recessed lighting. Other causes include overheating due to not using the right fixtures, or simply a bad batch of lightbulbs!
Can dimmers damage LED lights?
The simple answer is yes – there can be a fundamental incompatibility between the LED driver and the dimmer which leads to spurious and often very large current pulses into the driver. Oscillogram 1 shows the measured LED voltage (red) and current (yellow) of a GU10 LED lamp being dimmed with an incompatible dimmer.
Do dimmers shorten LED bulb life?
Since dimming, either by reducing current or by pulse width modulation, results in lower overall junction temperatures, it will have no negative impact on LED life; it might even extend life.
What affects LED lifespan?
The electrical stress: Running LEDs at currents higher than specified make the LED run hot. This can happen with wrongly matched drivers. For example, if the driver produces 700mA but the LED needs 350mA, this will put stress on LED and reduce its lifespan.
Will higher voltage make LED brighter?
Adjusting the voltage lower or higher will change the brightness, but only because it also changes the current- higher voltage means the current will increase in an LED.
How much is 50000 hours?
50,000 hours is over 2,083 days.
Why do LED lights not last long?
LED Bulbs Degrade Over Time
Instead, they slowly degrade, their maximum brightness getting lower and lower over time. When LED bulb manufacturers come up with the number of hours that an LED bulb can last, that number actually includes a little bit of time where the bulb is slowly degrading.
Why do LED lights not last?
Unlike incandescent light bulbs, LEDs don’t produce light using heat. This is part of what makes them so energy efficient. The downside is that their components can be sensitive to overheating, which can cause them to burn out prematurely.
