1.12.4 View Angle Degree
The view angle degree is referred to as directivity, or the directional
pattern of an LED light beam. The expressed degree dictates the
width of the light beam. Also, it controls to some extent the light
intensity of an LED. View angles range from 8 to 160 degrees and are
provided through the use of optics, which are special lenses made to
collimate light into a desired view angle.

1.12.5 Voltage
Voltage is the rate at which energy is drawn from a source, thus pro-
ducing a flow of electricity, or amperage, in a circuit. The difference in
electrical charge between two points in a circuit is expressed as
volts.

1.12.6 Voltage Regulator
A voltage regulator is a device that limits or controls and stabilizes
the voltage being applied to usage units such as LED lights and
motors. A regulator also takes higher voltages than required and
reduces them to the working voltage that makes a specific product
run correctly. In many instances, the lack of a voltage regulator will
allow higher voltage in than a product can manage and as a result
will cause irreparable damage to the product.

1.12.7 Volts
A volt is the International System unit of electric potential and elec-
tromotive force, and is equal to the difference of electric potential
between two points on a conducting wire carrying a constant current
of one ampere when the power dissipated between the points is one
watt.

1.12.8 Waterproof
Waterproof means that the LED product can be submerged into calm
water. However, there is a limited depth as stated for each specific
product, and this must be specifically outlined regarding “submer-
sion.” It also means that the product is made to withstand water being
splashed onto it like rain, or having snow fall on it. Waterproof prod-
ucts are made of high-grade stainless steel, aluminum, or high-
strength plastics.

1.12.9 Watts
A watt is the unit for measuring electrical power. It defines the
rate of energy consumption by an electrical device when it is in
operation. The energy cost of operating an electrical device is cal-
culated as its wattage times the hours of use. In single-phase circuits,
