After install a replacement HID bulb, adjust the beam pattern on a correct position

About incorrect beam pattern:

Each headlight bulb has tolerance during production, only 1 mm tolerance can make a big different on the position of beam pattern.

And also each Brand bulb’s performance might be different when installed on different headlight assembly.

So after installed a replacement of bulb, it is necessary to adjust the beam pattern on a correct position through the adjustment screw.

Without proper projection of beam pattern, will make people feel the brightness is low.

For comparing beam pattern correctly, we suggest you to project the light towards the wall and then adjust the headlamp.

Professional 3D Equipment Ensure the Perfect Beam Pattern

BRIGHTSTAR HID bulbs have hexagon-shaped arc tube with flat sides to meet the E-MARK standard beam pattern.

For ensuring the most correct electrode position, we developed 3D Electrode Horizontal and Vertical Range Calibrator and utilizing the 3D view to align electrode position correctly from up to down, left to right and front to back.

What Makes an OE Quality Gas Discharge Bulb?

Unlike the conventional halogen bulbs, it is time to replace the OE HID bulbs on your vehicle headlamps when they’re not able to be turned on the very first time, “cold start” so to speak, due to high stress and voltages on startup, even if the bulbs can be ignited after trying to turn on and off in quick succession.
The phenomenon implies that you’re gambling your safety with the initial sign of failure. The bulbs are very likely to fail to work when you need to see.

The market is now crowded with extremely cheap HID bulbs.
The competing manufactures are underpricing in order to get orders and market
share.They use cheap material to reduce cost and do not follow specifications to
produce safety product.
We would like to share with you what to look for to replace the failed OE HID bulbs on the vehicle based on our long-term experience and expertise.

Part 1: Electrodes

Features Effects
E-MARKD HID BULBS 
Made from thoriated tungsten.
1-2% of the electrodes are made up of thorium dioxide (ThO2)
Benefit of ThO2 is that it has a more even heat profile and current flow which promotes a more stable arc across the salt gap. 
Makes the bulb last longer because the electrode is more robust.
ThO2 produces a more stable and consistent light output while putting minimal stress on the salts themselves.

NON-CERTIFIED HID BULBS 
Cheap bulbs generally are made of pure tungsten which is super cheap, and super crap. 
It erodes quickly, and the bulb life is short.
Light output can be “wavy” or inconsistent over temperature and/or time.
Less brighter with a tungsten electrodes.

Part 2 : Metal Salt (the HIDs heart)

Features Effects
E-MARKD HID BULBS 
The salt is the heart of your bulb and is used as fuel essentially.
OE HID bulbs are made of Scandium Iodide and Sodium Iodide.
Every company has a closely guarded recipe of salts to make the precise colours. 
Once the plasma is created and the salts are vapourized, the ballasts can drop the voltage to 85vac and generally it is +/- 17vac to keep the arc going steadily.
Creat more stable plasma and light output.

NON-CERTIFIED HID BULBS 
Low quality salts and/or salts cut with other materials.
The less salt in the chamber, the less salt vapour and the plasma is more unpredictable generally producing more heat and less light output. 
Poor quality metal salts to barely allow the plasma to form and are easily diluted.
These bulbs run hotter and again unevenly.
