Before the advent of light bulbs that were friendlier to the environment, picking out a new bulb for your fixture was fairly straightforward. You walked down the right aisle of the store, looked at wattage and picked one. Today, LEDs are taking over and they are anything but simple until you get used to purchasing them. If you are just taking your first steps into the world of LED bulbs, you may have noticed several terms that you aren’t entirely familiar with. Here is a quick tutorial.
SSL stands for “Solid State Lighting.” It is how LED systems operate. These bulbs use a semiconductor instead of the typical filament or arc tube.
When some manufacturers make LEDs, they sort them into bins. These bins each contain bulbs of a certain color or overall lumen output. Some manufacturers only make bulbs based on a specific number of bins. When this occurs, they will list or label the LEDs as “binned.”
If you have a color-changing bulb on your hands, it will be termed an RGB (red, green, and blue).
4. Dynamic White
Some bulbs will throw light in a range of color temperature. These are called dynamic white and must be used with a special controller.
5. Warm Dim
A warming dim LED replaces a traditional incandescent bulb that is dimmed. The resulting light is warmer than that of a typical LED.
Some LEDs focus light in a specific direction. Other bulbs throw light in a full range, similar to incandescents. Omni-directional tells you that your bulb will put off light in all directions.
7. L70, LM79 and LM80
When you see these numbers, you know that the brightness of the bulb does not drop below a certain percentage after a specific amount of time has passed during testing. For example, if you see LM70 60,000 hours, the brightness of the bulb did not drop below 70% of its original output after 60,000 hours of use.
The brightness of a bulb compared to your cost savings is bulb efficacy. This is typically shown as LPW, lm/W or lumens per watt on the packaging.
There are other terms when it comes to LEDs, but those above are what the typical consumer is interested in. If you would like more information about LEDs, their cost savings and their impact on the environment, be sure to browse through our website for more information.
