Optimum Series 4
LED Headlight Bulbs

The Optimum Series 4 LED Headlight Bulbs are the optimum in quality, brightness, and beam pattern accuracy.

H11 Optimum Series 4 LED Headlight Bulbs.

GTR Lighting and Headlight Revolution have sold the exact same bulbs, just under the GTR Lighting Ultra Series Gen 3 brand name, since late 2016 for $199-$239. We both use the same manufacturer. The only difference is the price and brand name. Due to the heavy competition in this market, even though our bulbs are worth more, we are priced well below GTR Lighting, and even other brands that don’t have the quality or brightness of ours. Why pay more for just a name when the product is exactly the same, or a different brand that is more expensive, but inferior to ours in every way? Trust in us to provide you with the best LED headlight bulb on the market at a very competitive and fair price. We haven’t had an unhappy customer or negative review yet, and don’t ever plan to. 


Description

  • Single and dual beam LED headlight bulbs engineered to OEM specifications to match the beam pattern and fit of the original halogen bulb, so they won’t blind oncoming drivers. 
  • Due to the advanced design, paired with the exclusive reflector technology surrounding the LED chips, they have the most precise beam pattern in the industry. 
  • High quality Philips-Lumileds Luxeon Z ES LED chips are used to create an LED pattern that accurately matches the original halogen bulb filament placement. 
  • The fan-less heat sink is designed to create negative cavity pressure as it heats up, to pull in cooler air for constant circulation. Smaller than most, and fits more vehicles than most. No annoying fan noise, fans burning out, or slowing down when they get dirty, and/or clogged. Also, no annoying braids from the other type of heat sink, that due to lack of space, need to be tucked away, thus decreasing their efficiency. 
  • The Nano cooling material, pure copper PCB (circuit board), top grade high density aluminum, and Dow Corning silicone grease all assist the thermal conductivity, so the bulb runs cooler.
  • Compatibility: Fits any vehicle year, make, or model with a halogen headlight bulb. Just choose the bulb number that is correct for your vehicle. You can find the bulb number in your owners manual, or send us an email with your year/make/model via the Contact page, and we‘ll be happy to help.
