The 3rd Generation GTR Lighting Ultra Series LED Headlight Bulbs are the brightest LED headlight and fog light bulbs on the market. They have a more precise beam pattern hot spot than any others, the fit more vehicle applications better than others, and they use less wattage, and less Lumen than others but create significantly more light! If you're not convinced, please click here to see our test results on OEM headlight housing applications!
The Ultra Series bulbs come in all major headlight and fog light styles and they are brighter than any incandescent/halogen light bulb. They use a specially designed Convection Plate style heat sink that stays cooler on one side than the other so it can pull the hot air out of the heat sink. The benefit of this high-tech design is to not use a fan or messy braided heat sinks. Our simple design is effective and compact.
The Ultra Series LED bulbs feature super high quality LED chips from the Philips-Lumileds Luxeon Z ES family. This is one of the newest LED technologies on the market and allows us to create an LED array that most similarly resembles the original halogen bulb filament placed perfectly inside the headlight. This new way of thinking about how to use LEDs in a automotive headlight, paired with our exclusive reflector technology surrounding the bulb gives the 3rd Generation Ultra Series LED the best beam patterns in the industry!
These bulbs labeled "H4" are interchangeable with these other bulb numbers, they are all practically identical: H4, 9003, HB2.
The GTR Lighting Ultra Series LED Headlight Bulbs are suitable for both headlights and fog lights on any vehicle with a standard 12/14v DC electrical system. They are available in every normal bulb style and keep in mind, some bulbs have more than one name but they are the same thing (e.g. H4 is also called 9003). If you have questions, please send our sales team an email with your vehicle information and we will help you out as best as we can!
Projector Headlights: Generally speaking the best thing to use in a projector application is either a halogen (if it was designed for that) or an HID/Xenon bulb (if it was designed for that). Using an LED bulb will work on some halogen projector applications but chances are doing an HID conversion will yield better/brighter light than ANY LED bulb. The technology used in designing this LED bulb is based on mimicking the attributes of a halogen/incandescent bulb, so any halogen housing they should work but your results may vary.
