What’s the Difference Between Incandescent and LED Light Bulbs March 5, 2015Posted by bowmanlamps in Uncategorized.
Walk down any super store lighting isle, and you will notice that LED ( Light Emitting Diode) light bulbs are gaining in popularity. There is a plethora of styles, light colors, dimmable, non-dimmable – you name it and there is a LED light bulb to meet the need. So what’s the difference, besides price, between the old technology of incandescent light bulbs and the ever-improving technology of LED lighting?
Incandescent light bulbs, or lamps as they are known in the lighting industry, are produced by blowing hot glass into molds. When cooled, the glass is coated with a diffusing material. A very thin, tungsten filament is placed inside, and a base is added. Electric current is used to heat the filament, which generates the light. Although people like the light generated, only about 10% of the energy used results in visible light. The remaining energy seems to be given off as heat.
LED light sources are gaining popularity simply because they use less energy to produce quality, long-lasting light. They are made differently than incandescents, and are suprisingly stong, and able to be assembled in many shapes. Powered by a light-emitting semiconductor, the lights are also available in a variety of color.
Light is emitted through a diode – a device which allows current to flow in only one direction. Light is created when the energy flowing in to a chip is released. The color of the light depends on the ingredients and processes used.
LEDs also have advantages over other lights, including:
- High energy efficiency. Up to 85% more efficient than incandescents
- Low heat
- Low voltage and current requirements
- High levels of brightness
- Very reliable. Resistant to shock and vibration
- Long life. 20,000 to 50,000 hours.
- No UV rays
Lighting manufacturers have switched their focus to LED replacement lamps and fixtures. I can’t wait to see what comes next. I’m waiting for a three-way version. Use coupon code Take10 for 10% off during check-out for quality TCP LED lighting at www.bowmnlamps.com.
