HID (High Intensity Discharge) refers to lighting technology that relies on an electrical charge to ignite xenon gas contained in a sealed bulb. ? Unlike halogen bulbs, HID’s emit a type of light that closely resembles natural daylight and is therefore easier on human eyes. In fact, HID lights are currently used in most sports arenas, stadiums, and train stations worldwide. Kensun HID DC Ballast Conversion Kits are easy to install and are a sight to behold in action. Direct current (DC) is the unidirectional flow of electric charge (Most automotive applications use DC). The electric charge flows in a constant direction, distinguishing it from alternating current (AC). Emitting a light that is 3 times brighter than ordinary halogen bulbs, HID lights greatly assist in providing a clearer and expanded view of what is ahead. Everything you need for installation is packaged with the kit. Please check with your local law enforcement agency before using the HID light as diffrerent cities in the US have different laws regarding the use of High Intensity vehicle lights, or you can use for off-road vehicles and show vehicles. What is HID Color Temperature? Color Temperature is a measurement in Degrees Kelvin that indicates the hue of a light source, in this case the HID bulb. Color temperature is a characteristic of light that is sometimes misunderstood as brightness, when it’s more closely related to cool and warm color tones of light. While cool and warm are words used to describe a light’s temperature, this may be a bit misleading. The term color temperature actually refers to the color that is associated with the amount of heat needed to produce a color in from an ideal black body. Here is a rough guide to Color Temperatures for our HID bulbs. It is hard to describe HID colors accurately because different people tend to perceive colors slightly differently.
