The useful life of an LED used in a flameless candle can exceedhours which would equate to over 11 years if the LED were left on 24 hours per day. Heat is typically the mechanism behind both wire filament bulb failure and LED failure. LEDs are unlike traditional filament bulbs in the sense that they have a semiconductor die see below instead of a wire filament.
For example, a manufacturer of the LED, which is supplied to the flameless candle manufacturer, may run a production batch of 1, LEDs, and they will all have almost exactly the same color temperature due to very minor differences in the production process however, the next batch of 1, LEDs run a month or so later may have a more noticeable difference in color temperature than the previous batch which can result in visually noticeable differences in color temperature.įlameless candle manufacturers and LED manufacturers attempt to try and keep these color temperature variations to a minimum, but nothing is perfect. In addition to LED differences from manufacturer to manufacturer, there may also be slight differences in color temperature between different production batches of the same LED. Question: Why does the LED color seem to vary from candle to candle? The diagram below illustrates the different color temperatures for light sources. Answer: The advantages of flameless LED candles over real candles are numerous, and there are very few disadvantages.īelow is a long list of advantages and a very short list of disadvantages. Question: What are the advantages and disadvantages of flameless LED candles vs.
