i thought some of these would be useful for the ones who are doing retros themselves.
whats the difference between d2s bulbs, and d2r?
d2s oem bulbs -came in cars with projectors ie, tl, s2k, evo
d2r oem bulbs -came in cars w/o projectors ie, older tl, is300, g35, sti's (pre 2006)
Whats the difference?
d2r's have a brown band around the bulb itself to block some of the light. the housings they go in, also have shield directly underneath the bulb to give a cutoff.
What do I need?
1 pair of d2s bulbs
1 pair of ballast w/ internal ignitor (to save space) 35w or 55w DO NOT USE ANYTHING BUT OEM!!!
Lighting Terminology
AMPERE (AMP) - The unit used to measure the strength of an electric current.
ARC - The luminous discharge of electricity between two electrodes in HID lighting.
ARC DISCHARGE - A transfer of electricity across two electrodes (anode and cathode), characterized by high electrode current densities and a low voltage drop at the electrode
BALLAST - An auxiliary piece of equipment designed to start and to properly control the flow of power to gas discharge light sources such as fluorescent and high intensity discharge lamps. In metal halide systems, it is composed of the transformer, capacitor and connecting wiring; sodium systems require an ignitor in addition to the transformer and capacitor.
BU - An industry code indicating that the bulb is to be operated only in a base up position.
CANDELA (CD) - A unit of luminous intensity in a given direction, equal to one lumen per steradian.
CANDLEPOWER (CP) - The luminous intensity of a light source, as expressed in candelas
CAPACITOR - An electronic device that can store electrical charge. The capacitor is one of the main components of an HID lighting ballast. Because they can store a very strong electrical charge, capacitors can be very dangerous to someone who is unaware of this fact and opens a ballast in order to examine or repair it. If one does not know how to safely discharge the stored electricity, one should allow a trained technician to do any ballast repairs.
DOME - The portion of an HID outer bulb located opposite base (the neck and threads).
DOME SUPPORT - The spring-like brackets which mount the arc tube within the outer envelope (bulb).
ELECTRODES - Filaments located at either end of a discharge lamp that maintain an electrical arc between them. See arc discharge.
HALOGEN LAMP - A short name for the tungsten-halogen lamp. Halogen lamps are high pressure incandescent lamps containing halogen gases such as iodine or bromine which allow the filaments to be operated at higher temperatures and higher efficacies. While excellent for home lighting and similar applications, halogen lamps are not effective or efficient as grow lights due to their limited spectrum and high operating temperatures.
HID - The popular acronym for High Intensity Discharge.
HIGH-INTENSITY DISCHARGE (HID) LAMP - A general term for mercury, metal halide and high-pressure sodium lamps. HID lamps contain compact arc tubes which enclose various gases and metal salts operating at relatively high pressures and temperatures.
HOT SPOT - The area immediately under an HID lamp where the light intensity is strongest. Hot spots cause uneven growth, but can be remedied by using light movers.
IGNITOR - A component of the ballast necessary for the starting of the bulb in sodium systems.
ILLUMINANCE - The density of incident luminous flux on a surface; illuminance is the standard metric for lighting levels, and is measured in lux (lx) or footcandles (fc).
ILLUMINATION - The act of illuminating or state of being illuminated. This term is often used incorrectly in place of the term illuminance to denote the density of luminous flux on a surface.
INCANDESCENT LAMP - A light source which generates light utilizing a thin filament wire (usually of tungsten) heated to white heat by an electric current passing through it. Incandescent lamps are the most familiar type of light source, with countless application in homes, stores and other commercial settings. Light is produced by passing electric current through a thin wire filament, usually a tungsten. Incandescent lamps are totally ineffective as grow lights; they have very limited spectrum, are very inefficient in their conversion of electrical power to lumens of light output (lumen-to-watt ratio). They also put off far too much heat per watt to use in horticulture, even if the above-mentioned problems did not exist.
INTENSITY - A term referring to the magnitude of light energy per unit; light intensity diminishes evenly as you get further from the source.
KELVIN TEMPERATURE (K) - The unit of measurement to express the color (spectrum) of light emitted by a lamp; the absolute temperature of a blackbody radiator having a chromaticity equal to that of the light source (see correlated color temperature). A standard clear metal halide HID lamp has an average Kelvin temperature rating of 4,000K.
KILOWATT (kW) - A unit of electric power usage equal to 1,000 watts.
KILOWATT HOUR (kWh) - A measurement of electric energy. A kilowatt hour is equal to 1,000 watts of power used over a period of one hour.
LAMP - An electrically energized source of light, commonly called a bulb or tube.
LIGHT - Radiant energy which can be sensed or seen by the human eye. The term generally applied to the visible energy from a source. Light is usually measured in lumens or candlepower. When light strikes a surface, it is either absorbed, reflected or transmitted. Visible light is measured in lumens.
LUMEN - A measurement of light output; refers to the amount of light emitted by one candle that falls on one square foot of surface located at a distance of one foot from the candle.
LUX - A standard unit of illuminance. One lux is equal to one lumen per square meter.
METAL HALIDE LAMP - A high-intensity-discharge lamp in which the light is produced by arcing electricity through a mixture of metal halides. The light produced by metal halide lamps is in the white-blue spectrum, which encourages vegetative growth and "bushiness" while discouraging upward growth. This is the bulb to use in the first, vegetative phase of plant growth.
MERCURY VAPOR LAMPS - The oldest member of the HID family, mercury vapor lamps work by arcing electricity through mercury vapor. While more efficient than incandescent, halogen and fluorescent lamps, mercury vapor lamps have the least efficient lumen-to-watt ratio of the entire HID family. This, combined with an improper color spectrum for horticultural applications, makes mercury vapor lamps a poor choice for a grow light.
PARABOLIC REFLECTOR - A lighting distribution control device that is designed to redirect the light from an HID lamp in a specific direction. In most applications, the parabolic device directs light down and away from the direct glare zone.
PHOTOSYNTHESIS - The growth process by which plants build chemical compounds (carbohydrates) from light energy, water and CO2 (carbon dioxide).
REFLECTOR - The term sometimes used to refer to the reflective hood of an HID lamp.
SOCKET - The threaded, wired receptacle that an HID bulb screws into.
TRANSFORMER - The component in the ballast that transforms electric current from one voltage to another.
WATT (W) - A unit used to measure electric power. One watt equals one joule/second.

This projector usually comes with a cut-off shield that has OEM mounting brackets integrated. Most would usually cut these off and make their own holes for mounting. Subaru Legacy Halogen projector is almost idnetical to this Xenon projector. We used cut-off shield from the Legacy projector as it is smaller and has mounting holes built-in. All measurements are to reflect shield replacement. Height and width measurements are also given for an actual Xenon reflective bowl.

Lexus LS430 Super Wide Low Beam (Stanley):
Measurements for this projector are provided as "naked" - shroud removed, OEM mounting bracket removed, supplemental reflector was included in measurements. Also, assumed some "fat" (eg.: AFS spindles) would be trimmed. Where it says "trimmed", this is only an assumptive place where it was deemed best to trim without too much sacrifice. Some people will choose to trim more or not to use the whole or most of the shroud that gives this projector most of it's bulk. Please remeber that this is a very large projector/shroud combination.
Diameter = not measured as this projector comes with it's own shroud
Height = 117.05mm

Trimmed Height = 131.70mm
Max Width = 173.15mm
Trimmed Width = 154.30mm
follow these steps
1. park on level ground, 25 feet from a wall
2. measure the height from the ground to the center of the headlight projector.
3. then measure that same distance up at the wall and make a mark.
4. the lower cutoff should shine 2-3inch below that mark.
Most of you already know hid bulb temps are measured in kelvin.
As a rule of thumb; the lower the temp, the high the light output.
It is recommend to use 4300k (which what 99.9% of the car manufacturers use. i pulled a bulb out of a wrecked mercedes and it end up being purple'ish. which indicates something around 12000k)
to get the best lighting performance possible out of your projectors
follow these steps
1. park on level ground, 25 feet from a wall
2. measure the height from the ground to the center of the headlight projector.
3. then measure that same distance up at the wall and make a mark.
4. the lower cutoff should shine 2-3inch below that mark.
A way to do this if you have cool toys is:
- Put a horizontal laser level on a tripod
- Point the laser level at the center of the projector by adjusting the tripod's height
- Swivel it around 180 degrees
- Put an object 25' away (I put my recycling bin at that distance)
- Measure 2.5" down from the laser line and put a piece of tape
- Adjust the driver's side projector until the lower side of the slope is even with the tape
- Adjust the passenger's side projector until the higher side of the slope is even with that of the driver's side.
