Description. BETTER THAN EVER: After nearly a decade of experience developing and refining our designs, sourcing the best quality raw materials, and gathering feedback from end-users on what makes the best LED bulb with the most effective beam pattern, we're proud of the new Ultra 2. This an LED bulb upgrade that is brighter. That has a better beam pattern. Lasts longer. Has more adjustability. And is easier to install. Now, the Ultra 2.0 is available with a yellow chipset for those who love to adventure out when the weather gets nasty!

BRIGHTER: The Ultra Series 2 bulbs from GTR Lighting utilize the best automotive grade multi-core LED chip technology to deliver ultra-bright light, in an ultra-focused beam pattern! Not only do the elec-tec automotive-grade NLW753 chips have more lumen density than popular (but now aging) options from CREE and Philips, but there’s more to it. We have optimized the position of the LEDs so that once locked into the fog light, they are directly in-line with what the optics of the projector or reflector was designed for which will provide you, the driver the most useful and safe beam pattern. The collars have full rotational adjustability. Put simply: You'll see a lot more, but without producing extra glare to oncoming traffic.

MORE RELIABLE: Performance aside, these are the last LED fog light bulbs you'll ever need! After many simulations, we arrived at a heat-sink design that is not only extremely effective at keeping the body of the bulb >80C, but looks cool too. Since maintaining low operating temperatures is key to LED lifespan, we've paired that with a bearing-less fan to actively cool the heat sink as well. The housing on our LED drivers is completely potted inside too, which is only possible with expensive-to-produce die-cast housings like the one that the Ultra 2 uses. Keeping cool and all components dry is crucial, and the Ultra 2 checks all the boxes.

BETTER FITMENT: We challenge you to find an alternative that produces the same amount of output with the same small footprint that the Ultra 2 has. Here we took a balanced approach between maximizing output and minimizing geometry so that they'll fit in every application. Too much power and an inadequate heatsink? Premature failure. Too much power and a massive heat sink? Great, but won't fit anywhere. Due to their superior optical focus they can create up to 10x more usable light than other LED bulb options even though they only produce 3,900 Lumen of light. If you're looking for the brightest option that's a sure fit, you've found it.

BEST WARRANTY: You can hit the road knowing that you'll be backed with a lifetime warranty from here on out. If in the rare case something goes wrong, GTR Lighting will replace the product quickly.
