No, LEDs do not contain mercury.
No, LEDs do not emit ultraviolet (UV) or infrared light.
Not all LEDs can be used with dimmer switches, so make sure you check with the manufacturer to see if your LED is compatible with dimming circuits. Litetronics dimmable LED light bulbs are specially engineered to dim down to 3% of light output on most standard triac dimmers.
Unlike other LED light bulbs, Litetronics LED PARfection bulbs do not have LEDs in the center of the bulb; rather, they have an array of LEDs around the perimeter of the bulb. The Eco-Clear optics lens focuses the light emitted by the LED array into an evenly controlled beam that provides even light distribution without glare or striations.
The Thermal Breeze cooling system is different from heat sinks in other LED light bulbs because it provides both internal and external cooling to the LEDs, which allows the LEDs to cool down in a shorter period of time and makes it possible for the bulb to generate more lumens in the same space while running at an optimal light level.
Additionally, the Thermal Breeze cooling system does not use heavy metal to manage heat. This means Litetronics LED light bulbs weigh much less than other LED light bulbs. In fact, they even weigh less than a halogen light bulb, so they are sure to meet the weight capacity of existing fixtures.
The LED PARfection bulbs have the Thermal Breeze cooling system that dissipates heat much better than ordinary LED heat sinks, which improves lumen output and LED performance. Thermal Breeze’s advanced cooling technology also means that the Litetronics LEDs stay cooler during operation compared to ordinary LEDs, and the lower temperature results in longer life. They also have an Eco-Clear optics lens that takes an outside LED array and focuses the light into a controlled beam with even light distribution in the center. The LED-DECO light bulbs have a unique LED mounting frame that provides omnidirectional light that makes chandeliers sparkle. They also have an internal, concealed heat sink that enhances the aesthetics of the bulbs.
While an LED can generate light for up to 100,000 hours, its lumen output gradually decreases over time. The industry standard is to provide a life rating that is the point at which the lumen maintenance is 70%. In other words, the average rated life for an LED tells you how many hours the LED will last and maintain at least 70% of its initial lumen output.
This is different from how the average rated life is determined for other light sources (incandescent, halogen, fluorescent, etc.). Other light sources measure the average rated life as the point at which 50% of the bulbs tested have failed and 50% of the bulbs tested are still burning. LED light bulbs measure the point at which they provide 70% of initial lumens because LEDs fade over time, and this rating gives end users an idea of how long the LEDs will provide useable light that meets the needs of the application.
Most LED light bulbs have an average rated life of 25,000-50,000 hours. There are many factors that account for the variance in lifespan, including heat management, proximity of LEDs to one another, the type of fixture, etc.
LED light bulbs have many benefits. Compared to incandescent and halogen light bulbs, LEDs can provide tremendous energy savings, and their long life can provide even more savings in maintenance and replacement costs. Compared to fluorescent lighting, LED is able to provide more controlled, focused beams of light and better dimmability. It is also considered to be more environmentally friendly because it has a longer life and does not contain any mercury. It also does not require warm-up time; LED light bulbs turn on instantly with full brightness when the light switch is flipped.
LED light bulbs are much more energy efficient than incandescent light bulbs, reducing energy consumption by up to 85%. Compared to compact fluorescent bulbs, LEDs are fairly comparable in terms of energy savings. LED’s major advantages over CFLs are the ability to provide a controlled beam of light for reflector applications and its dimmability. LED’s long life of up to 50,000 hours is much longer than both incandescent and fluorescent bulbs, which helps reduce maintenance and replacement costs.
A heat sink is a conductor specially designed to dissipate heat. They are used in LEDs because they are very heat sensitive. As the LEDs generate light, they also give off some heat. When several LEDs are next to each other in a bulb, heat builds up and can lower the LEDs’ performance. A heat sink dissipates the heat to keep the LEDs performing optimally.
LED stands for light emitting diode, which is a semiconductor device that emits visible light when electrical current passes through it.
