How does the quality of LEDs affect you?
Many of us buy the lowest-priced brand light only considering the required wattage. Even a little understanding will convince you that this is not the right method of evaluating, Consider for example:
- Two brands of the same wattage may give a difference in brightness, this means even the lower wattage of the brighter light could have been used resulting in savings in electricity.
- The life of the two different brands may not be the same. One may last longer than the other.
- The deterioration in brightness with time may be different in the two brands.
- The average failure rate of the lights over the estimated life may be different.
From the above examples you must have understood that buying the lowest priced LED light of the given wattage isn’t the best choice, it may turn out to be costlier. Let us understand the components of the LED light and how it affects the quality of the light.
Components that differentiate the quality of LED Lights:
The LED illuminator is a chip. Larger chips provide more lights, good stability against current variations, but it costs more. Cheap and small led chips provide less light and stability. Ceramic COB lights are totally different in terms of size, they use multiple small chips to provide more lights and stability. Lower quality LED lights will be inconsistent in color, even if they are marketed as the same color temperature.
LED Driver :
LED Driver directly affects the life of LEDs. The LED breaks down mainly due to the drive circuit.
A huge part of determining a LED’s quality is how the bulb manages heat. In order to live out their 50,000+ hour lifespan, they must effectively and efficiently pull heat away from the LED. Quality LED lights use metal heat sinks with fins to pull away and store the heat the light produces. Cheaply made LEDs may use fans or plastic heat sinks to try and pull heat away. These methods of managing heat are more likely to fail, lowering your light’s life expectancy.
Quality of Phosphor:
Another costly thing in LED lights is rare-earth phosphor. Cheap producers use low-quality phosphor to lower the cost. If you see spotlights with slightly different colors of white, it might be a sign of low quality. Maintaining the same colors in white is a challenging task for LED producers. Color rendering is also a point to be considered. Cheap LED lights generally don’t have good CRI, As good CRI also requires high-quality phosphor.
Led needs to be driven with constant current DC supply for longer life. What makes LED drivers unreliable? Low-quality components and low-life capacitors make them unreliable. Non-branded Chinese LED drivers use regular capacitors which work for only 1000 hours at elevated temperature.
- There are many more components affecting the quality of light, like the lens or optics diffuser, housing, base, etc. but we are only covering the main components here.
