LED

A light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many devices and gaining popularity in use in home and automotive lighting sources as their brightness levels increase.

 

Lumens

The total measure of light output from a source.

 

Lux

Just because a LED system has a higher lumen output, doesn’t mean it will “appear” brighter when you look directly at it. Looking directly at the source of light will tell you the lux, or amount of light that specifically reaches your eye. Some LED bulbs are designed with projectors to focus the light in one direction, and that will make them very bright in one direction, or a high lux, but from another angle, the brightness will decrease sharply. Lux is not a good measurement for automotive use because automotive housings are designed for use with incandescent bulbs to evenly distribute light in all directions. Different housings are designed for different purposes. For example, a headlight will collect and focus the light forwards, and a side marker will collect and disperse the light to as much area as possible. Because the housing determines the light path of the bulb, the same bulb can look completely different in two different housings, thus producing conflicting lux ratings.

 

Bulb Out Warning/ Warning Cancellers

When a bulb burns out the current stops flowing through the circuit. In most modern cars this triggers a sensor within the electrical system and a warning on your dash or vehicle information center. It could be the circuit has been disrupted for a different reason other than a burnt out bulb but it is most likely a dead bulb. Some cars, when retrofitted with HID or LED systems, display a bulb out warning despite the retrofitted system functioning perfectly fine. A warning canceller is a simple resistor, diode and capacitor system designed to safely eliminate your false bulb out warning light by imitating the operation of the stock headlight system.

 

PWM (Pulse Width Modulation)

Pulse width modulation is an alternating electrical signal on the headlight circuits to extend the life of halogen bulbs. PWM systems can disrupt the operation of an LED Driver or HID ballast, so our solution with the REVOLUTION is to offer a PWM-specific harness. For the PRECISION there is no need for extra wiring as this system in built into the LED Driver.

 

LED Driver

An LED driver is the power supply for an LED projector system using the power wiring from your vehicles stock lighting system.

 

Bi-LED

This refers to the capability of our LED projector systems to function both as both a high and low beam source. Some headlight housings have both the low beam and high-beam using the same bulb; our projectors work the same way – the high beam is activated by powering a solenoid on the bottom of the projector to flip a plate located in the path of the low beam to alter output for high beam use.

 

HID

Refers to High Intensity Discharge or xenon bulb based lighting systems that predominantly use a projector housing but may also be reflector based. The components of an HID system are typically made up of a ballast, a bulb, and a projector or reflector housing. HID or xenon systems are popular amongst high end vehicles and these systems can be retrofitted into some vehicles. They produce sharp, pure white light.

 

Ballast

The component of a xenon or HID lighting system that provides power to the bulbs using the vehicles headlight wiring system. This is the HID or xenon equivalent of an LED Driver.

 

Shroud

The decorative and functional cover used on HID and LED projectors to mask and protect a projector housing within a headlight. Shrouds come in a variety of styles and sizes to suit each individual headlight retrofit or build.

 

Wire Harness

There are a few different types of wiring harnesses that suit a few different purposes within an LED or HID retrofit. On older cars, the headlight circuit does not produce enough electricity to properly power an HID ballast, so one type of wiring harness contains relays and switching diodes in order to pull electricity from the cars battery and power the ballasts in order to prevent unsafe strain on the headlight wiring. Another type of wiring harness is a simple length of wire that adapts a certain plug on the end of your vehicles headlight power wires to the plug required to power an LED driver. A third common harness places a bulb out warning circuit in between the vehicles headlight wiring and the LED driver in order to eliminate a bulb out warning light or to deal with a vehicle that has Pulse Width Modulation system.

 

 JB Weld

An epoxy system popular amongst people that modify headlights. Once hardened it develops strong bond between two surfaces that is both resistant to extreme heat and moisture. Often used to weld projectors into place in headlight housings, repair cracks in projector bowls, attach mounting points permanently, etc.

 

High Intensity Optics

Refers to the projector reflector bowl and LED placement within the projector housing. Arced Lighting LED projectors are designed with the experience of lighting engineers and real world testing so that the light they produce is high in both clarity and intensity.

 

Kelvin

A rating of color temperature. Usually a number between 3000K-6000K in most automotive headlight systems or bulbs. Arced Lighting LED projectors emit at approximately 5500 Kelvin, much like midday sunlight or daylight.

 

Sharp White

Bright, clean and illuminating LED output rated at 5000-6000k like the sun on a bright day.
