How we Test

From Unknown to Fact

We utilize specific automotive housings, including the most common makes and models to provide a comprehensive result for the viewer. H7 bulbs are currently tested in halogen and aftermarket LED & HID situations, and D2S for OEM HID bulbs to ensure uniformity for results. Please keep in mind that other makes and models may differ, however our aim is to provide a comparison between each bulb brand and model in a controlled environment.

All tests are:
  • UNBIASED and true. We do not allow paid sponsors or endorsements
  • performed in a 0 lumens environment (pitch black)
  • tested in various headlight, foglight, etc. housings, and will vary depending on bulb type
  • verified peak brightness after specific warm-up times, as well as ambient brightness for certain bulbs types where it is important
  • taken using genuine and brand new products to ensure the most accurate results

High quality test equipment is used to ensure the most accurate and fair measurement possible. OE/factory equipment is utilized. We keep our test details updated and are subject to change (as we continue to enhance our processes). Please see below for all specifics.

LED Test Details

Reflector Headlight Specific Test Details:

  • An OEM 2009 VW Jetta (MK5) halogen headlight reflector (H7) was used for all reflector beam results set at 12 feet (3.66 meters)

Projector Headlight Specific Test Details:

  • An OEM 2009 Mercedes E550 halogen low beam headlight projector (H7) was used for low-beam results, and an OEM 2017 Kia Sorento halogen high beam projector (H7) was used for high-beam results, set at 12 feet (3.66 meters)

Number of Samples used on each chart: 2/each rating (low peak lux, high peak lux), 4 total for overall score

Overall Score is weighted from 1/2 of each Lux category

The LED charts compare the products to a stock halogen bulb (new OSRAM), and is sorted by best star rating (top to bottom)

Lumens is per 'kit' (two bulbs). Result is taken at exactly 2 minutes of runtime with ambient cooling. Integrating Sphere used for all lumens tests. Lumen results are not included in the Overall Output Score

Overall Score baseline for a Stock Halogen bulb is 2.5 Stars (baseline)

Percentage values are compared to a new OSRAM OE/Stock halogen bulb

Lux test results are per bulb (each). Result is taken at 2 minutes of runtime

Other Test Result Details:

  • CAN-BUS Compatiblity tested on a 2013 VW Jetta US-Spec, your result may vary
  • Claimed LED Brand is assumed based on sales material and may not be accurate
  • Dimmable as DRL tested at 6 volt on PWM
  • Heat Sink Temperature taken after 5 minutes runtime directly on heat sink
  • Noise reading taken at 1inch away from fan

Halogen Test Details

Number of Samples used on each chart: 2/each rating (low peak lux, high peak lux, lumens), 6 total for overall score

Overall Score is weighted from 1/3 of each Lux and Lumens categories

The Halogen charts are sorted by best star rating in each product category (top to bottom)

Lumens is per bulb (1). Result is taken at exactly 2 minutes of runtime with ambient cooling. Integrating Sphere used for all lumens tests.

Overall Score baseline for a Stock Halogen bulb is 2.5 Stars (baseline)

Lux test results are per bulb (each). Result is taken at 2 minutes of runtime

Aftermarket HID Test Details

Reflector Headlight Specific Test Details:

  • An OEM 2009 VW Jetta (MK5) halogen headlight reflector (H7) was used for all reflector beam results set at 12 feet (3.66 meters)

All HID bulbs were ran at about 12hrs to ensure burn in for accurate lux and kelvin values

Original 35 watt (or 55 watt) ballast included with each kit was used for testing

Number of Samples used on each chart: 2/each rating (low peak lux, high peak lux), 4 total for overall score

Overall Score is weighted from 1/2 of each Lux category

The HID charts are sorted by best star rating (top to bottom)

Overall Score baseline for a Stock Halogen bulb is 1.0 Stars (baseline)

Percentage values are compared to an OSRAM OE/Stock halogen bulb (new)

Lux test results are per bulb (each) taken at exactly 5 minutes of runtime with ambient cooling

OE HID (Xenon) Test Details

  • An OEM 03-08 Nissan Murano Bi-Xenon D2S Projector Lens, an OEM 04-08 Acura TL Bi-Xenon D2S Projector Lens, & an OEM 04-09 Lexus RX Xenon D2S Projector Lens were used for low beam and high beam (excludes Lexus RX Projector) results with a Morimoto 35watt Ballast, all at 25 feet (7.62 meters).

All HID bulbs were ran at about 12hrs to ensure burn in for accurate lux and kelvin values

Number of Samples used on each chart: 2/each per rating per projector/test (low peak lux, high peak lux, lumens), 12 total for overall score

Overall Score is weighted from 1/3 of each Lux and Lumens categories

The HID charts are sorted by best star rating in each product category (top to bottom)

Lumens is per bulb (1). Result is taken at exactly 5 minutes of runtime with ambient cooling. Integrating Sphere used for all lumens tests

Overall Score baseline for a Stock Halogen bulb is 2.5 Stars (baseline)

Percentage values are compared to an OSRAM OE/Stock HID bulb (new)

Lux test results are per bulb (each) taken at exactly 5 minutes of runtime with ambient cooling


Beam images taken with the same camera exposure settings, color is near true to life but will vary depending on your viewing screen

Kelvin/Color: Stock Halogen Color Temperature Kelvin is typically 3300k, Stock OE HID Color Temperature Kelvin is typically 4300k. Color shown is tested using a kelvin meter pointed at headlights output against a white test wall. Kelvin rating of 4000k has a yellow incandescent tint, 5000k is pure white, 6000k has a blue tint

We wil be bringing back column/data sorting in the future! We had to remove it to allow for responsive data flow. We appreciate your patience in the meantime

Additional tests are planned for future results. If you have any requests or products you would like to see tested, please feel free to contact us!

'Disclaimer: Test results performed may be performed at different dates, Results are not perfect and may vary depending on many factors including but not limited to manufactering defects and environmental variables. See Terms & Conditions for further information.
