Reverse bias: Although the LED is based on a diode junction and is nominally a rectifier, the reverse-breakdown mode for some types can occur at very low voltages and essentially any excess reverse bias can cause immediate degradation, and may lead to vastly accelerated failure. 5 V is a typical maximum reverse bias voltage specification for ...
1. Always Inspect Lights Before Hanging Them. The first thing you should do before hanging the Christmas lights is to inspect the plugs, wires, and sockets for any problems.
An LED holiday light. Light-emitting diode (LED) holiday lights are quickly gaining popularity in many places due to their low energy usage, long lifetime, and associated low maintenance. Colored LEDs are far more efficient at producing light than their colored incandescent counterparts.
Put your holiday lights on a timer. Time them to go on at sunset and off at bedtime. No one will notice them at noon. No one will be around to see them at 3 in the morning.
One-color light is well suited for traffic lights and signals, exit signs, emergency vehicle lighting, ships' navigation lights, and LED-based Christmas lights Because of their long life, fast switching times, and visibility in broad daylight due to their high output and focus, LEDs have been used in automotive brake lights and turn signals.
Modern LED lights that mimic the sun work well and are inexpensive. The key is placing the light near enough to the plant . A small grow light placed five feet above the plant probably won't cut it.
A twinkle bulb is a special type of light bulb which blinks on and off for decorative effect. They are most commonly used on Christmas lights and other string lights, but can also be used for other ornamental purposes like electric jack-o-lanterns for Halloween and replica traffic lights.
