Watts: Watts is NOT a measurement of light. It is the measurement of the power used to create the light.

Amp: The measurement of how fast an electric current flows.

Voltage: The force that causes a current of one ampere to flow through a conductor having a resistance of one ohm.

Lumen: Lumens is the measurement of light output (brightness). The higher the number of lumens, the brighter the light will be. The lower number of lumens, the dimmer the light will be. Different companies can use different watts to create the same amount of light as their competitors. This is why lumens should be looked at for the actual brightness of the light.

Kelvin: Kelvin is used to describe the color of light that is emitted. It will be a number followed by K. The higher the number, the brighter white the color will be. The lower the number the closer to a yellowish color it will be. Examples: 2700K will have a yellowish color and 6500K will have a bright white with a blueish hue.

Beam Angle: This is the angle of the points of both sides of the light spread where the light intensity drops in half.
