What is an LED light bulb?
An LED light bulb is a semiconductor chip that generates light when current is applied in the right conditions, which is very different from any other technology currently used in lighting. These chips (known as dies), are assembled in a structure that helps support and protect the dies and the electrical connections. This structure is generally known as a package. Depending on the type of LED package and the desired characteristics, there may be one or more LED dies per package. The different types of LED packages have different strengths and weaknesses that impact the package’s applicability in lighting. Of note, LED bulbs are more sensitive to operating temperature than other types of lighting, and anything from lifetime to acceptable current to chromaticity can be impacted by the operating temperature.
LED lights are quickly becoming the norm in the industry and a very promising technology, the high points:
- No mercury, making them a much cleaner alternative to fluorescent lamps.
- Low energy consumption compared to traditional lighting.
- Superior light quality and capability to tailor the light to the need.
- Life that is sometimes 10 to 20 times than some traditional lighting products.
- Most LED light bulbs contain no glass so are safe for food applications
- They contain little to on UV

LED Light Bulb Types
- Standard Shape - These are made to mimic the standard incandescent light bulb. A shaped lamps have a standard medium base socket and are dimmable
- LED Strip Lights - If you are looking to accent a wall or back light a particular area LED strip lights are a great solution. They are very affordable and easy to install. We can help you layout your project over the phone or through our online chat!
- Decorative - Chandelier bulbs are very popular and give a fantastic look to large conference rooms in hotels, restaurants and ballrooms. These lamps are typically 40-60 watt. LED chandelier bulbs are now dimmable and mimic the look of standard incandescent bulbs while saving you energy and cost on maintenance.
- Reflectors - Reflector flood lights are commonly used in downlights that you see in homes, commercial buildings and retail stores. The typical BR30 is a 65W bulb and these usually last upto 5,000 hours. The new LED BR30 light bulbs use only 9-10 watts and last upto 25,000 hours.
- Tubes - Installing LED T8 tubes in a commercial building can cut your energy usage in half. There have been many changes in the LED T8 market. What has emerged as the winner is the new InstantFit LED T8 lamp by Philips. These lamps are a direct retrofit for a standard fluorescent lamp, no rewiring needed. Just plug in, walk away now you have LED T8 tubes in your building!
What to Consider when Buying LED light bulbs
- Manufacturer Reputation - Start up LED bulb companies are coming and going daily. Many of these companies offer extremely long warranties and promises that stretch the capabilities of the technology. Price is not always the best deciding factor. Review the Lighting Facts label , the manufacturers warranty and how long they have been in business. AtlantaLightBulbs.com promote trusted brands such as PHILIPS, TCP, ProLED by Halco & CREE.
- Equivalent Wattage - Lumens are the new measurement of light output in the LED light bulb world. You can no longer base wattage on brightness, wattage now is just a function of the amount of power being consumed by the LED bulb. Reviewing the Lighting Facts label for comparison measurements helps, a base line is that generally will see 80 lumens per watt in LED.
- Lumens - Lumens are a measurement of the total amount of light that a given light source emits. This is the main number to look at when comparing lamps for equivalency.
- Color Temperature - CCT is a guideline used by the industry to map out the color of the light. As a general rule, starting at 2700K the light is warm like the color of a lit match. As you move up the scale to 5000K to 6000K the light becomes more white then blue. Read more about color temperature.
- Driver Content - Because of their design LEDs function on a driver. LED bulbs have to convert AC current to DC current to operate. Verify the driver being used is a quality one. The weakest link in an LED system is the driver, if the driver fails the LED fails.
