Product Description

H4 HID Kit - High Intensity Discharge - 9003 & HB2



The OEM halogen H4/9003 bulb uses a dual-filament bulb. One filament is used for the low beam and the other filment is used for the high beam. Accordingly, BMR offers two types of HID kits for the H4/9003 bulb. Single HID kits will offer the low-beam functionality only. High beam will be disabled. Dual beam HID kits will offer both low and high beam functionality. This is also referred to as bi-zenon.

What is Kelvin?    Kelvin (K) in relation to HID is the color temperature of light. That light color is on a spectrum that varies from 3,300k to 12,000k. Starting on the left, 3,300k is the color temperature of OEM halogen bulbs. 3,300k is kind of yellowish. The next step up would be 4,300k. 4,300k is the equivalent of sunlight. This will be the brightest and whitest color available with HID bulbs. If you are looking for strictly the brightest bulbs on the market, go with 4,300k. Next is 6,000k. 6,000k has a tint of blue and will be similar to many Infiniti/Nissan factory HID bulbs. 8,000k will be bluer than 6,000k and is similar to many factory BMW and Mercedes HID bulbs. 10,000k and 12,000k will shine a purple light. Although we have those colors available, we don't recommend it. Try and drive at night behind a purple light. These HID kits are more for show.

There is a misconception that color temperature is a rating of the brightness of the HID bulb. The truth is that the higher the color temperature, the less light output from the HID bulb. Again, if you're looking for the maximum amount of light from your HID kit, choose the 4,300k bulb.


What is Lumens?    Lumens in relation to HID is the intensity of light. In comparison to OEM halogen bulbs, HID bulbs are on average three to five times brighter. The lumens of an HID bulb will be at least three times greater than the lumens of an OEM halogen bulb. You could compare the power and intensity of HID with a welder's arc. Same principle and same type of light. Instead of a halogen bulb using a filament to create the light source, HID uses an electric arc to create light. This arc of light is far more intense than a halogen filament bulb.

More light = more power requirements    This is not true with HID bulbs. The HID kit will produce approximately 23,000 volts. Although a huge amount of power, the HID system will only draw 35 watts of current. The standard OEM halogen bulb will consume 55 watts of power. Therefore the HID system will draw far less current from your vehicle's electrical system. The power conversion is achieved with the use of a ballast. Like a florescent home lighting system, the florescent ballast generates more electricity for the bulb but consumes less electricity in comparison to a standard incandescent bulb.
