This device controls the amount of current in an electrical circuit, ensuring the fixture receives the correct amount of energy.

Color Changing / RGB

RGB signifies the primary colors red, green, and blue, which can be combined to create nearly any imaginable color.

Color Temperature

White lights can either have yellow (warm white) or blue (cool white) tints to them, and this number from around 2500-7000 represents the amount of this tinting.


A self-contained power supply which is similar to ballasts and transformers utilized in fluorescent and low-voltage bulbs.

Footcandle (fc)

Quite literally, this term refers to the amount of light that appears within the one square foot around a candle.

Ingress Protection (IP)

L70 Hours

Rather than flickering, LED bulbs will fade when they reach the end of their lifespans. When the bulb reaches 80% of its initial lumen output, it is considered to be at the end of its life. This measurement predicts how many hours it will take to reach 70%.


A way of measuring the amount of light a bulb creates and is equal to the amount of light emitted in one point by a single point of a candle.


The first generation of LED lights was only able to illuminate in one direction. Then, bulbs boasted 180 degree coverage. Finally, omni-directional bulbs were created that can illuminate the same amount of space as traditional incandescent bulbs.


The process where an existing fixture is upgraded with new parts to give it different capabilities, often to allow existing fixtures to support LED bulbs.

Solid State lighting

Commonly used to support LED bulbs, these fixtures convert electricity into light, rather than using gases and filaments.


According to the International System of Units, a watt measures the power require to power a bulb and equals one joule per second.
