Q1. Do LED lights burn out?

All lights have lumen depreciation, which means the light output slowly decreases over time.  Unlike other types of lighting, LED bulbs do not burn out, but slowly decrease in brightness.  Higher quality LED products have efficient heat sinks and LED chips. Heat sinks extract heat away from the LED junction and high quality LED Chips depreciate very slowly, while cheap chips can depreciate very rapidly.

End life of LED products rate at 70% of initial luminous flux, or 70% of the original light output.  All other lights from incandescent to metal halides burn out sooner and degrade much faster than LED lights.  All other lights typically rate at when they burn out, LED lights rate and when they stop producing enough light.  LEDs are more about lumen maintenance compared to end life.  Improvements in packaging and heat sinking are improving the lumen maintenance characteristics of illumination-grade LEDs.

Q2. How do dimmable LED lights work?

The dimming design uses the most updated technology of Frequency and Peak Current Modulation, which provides even and stable dimming function ranged from 1% to 100% of full luminous flux. Pulse Width Modulation presents a technique to safely dim an LED from 1-100% of its nominal brightness. By pulsing the LED with current, and varying the duty cycle of the current waveform, the LED rapidly transitions between on and off, and the relative times spent give the impression of being dimmed.  Digital fade dimmers should be avoided.

Q3. Do LEDs attract insects?

No they do not. Insects see entirely different spectrums of light and are attracted to ultraviolet light. A side note - flowers create "nectar guides", invisible to the human eye and ultraviolet light attracts insects to flowers for reproductive purposes. This is not to say that all bugs aren't attracted to LED lights, but most can't see the light that LEDs produce.
