GTR Lighting Ultra Series 3 LED Review
A polished premium LED kit with strong reflector output, very good projector performance, and clean 5100K color—but its $259 price makes it a quality-first choice, not a value play.

Our verdict
The Ultra Series 3 suits someone willing to pay for a premium LED kit with strong results in both of our reference housings. It combines strong reflector output, very good projector performance, stable warmed-up output, and refined hardware. The main tradeoffs are the roughly $259 price, its power draw and rear cooling hardware, and reflector glare that still makes housing choice and aiming important.
What we liked
- Strong output gains in both the reflector and projector tests.
- Clean 5100K color and only a 2.8% output drop from two to 30 minutes.
- Refined construction, an internal driver, and no warning lights or flicker in our bench test.
What to consider
- At roughly $259, it is a premium choice rather than a value-focused upgrade.
- The 43.1-watt-per-bulb draw and rear fan require electrical and clearance checks.
- Reflector glare was not among the lowest we measured; exact-vehicle fitment, DRL and RFI behavior, and lifespan remain unconfirmed.
Build quality
GTR Lighting's Ultra Series 2 had a strong track record in our testing, so the question was whether the Ultra 3 was a meaningful revision or the same idea with a new name.
Out of the box, its machining, cooling design, wiring, and overall fit felt more refined than the average low-cost LED kit. The flat diode boards are neatly positioned, the finned body feels substantial, and the internal driver avoids another box and set of connections inside a tight housing. Those are useful construction details, but the measured results below—not the finish or packaging—determine how well the kit performs.
Reflector headlight performance
In our reflector test, the Ultra 3 produced unusually strong low- and high-beam output with a clear hotspot. The separate 2/5 beam-pattern rating and 380-lux glare result keep it from being a top pattern result, so housing choice and aiming remain important.
About these tests: The reflector and projector measurements below come from BulbFacts reference housings so products can be compared consistently. They are not exact-vehicle tests; bulb seating, housing optics, lens condition, and aim can change output, glare, and beam shape. The selected-vehicle panel above remains the source for any known applicability evidence.

We measured 1,498 lux on low beam, a 302% increase over the standard-halogen baseline for this test. That is a substantial gain in the reference housing, not just a change created by the whiter color.
High beam measured 2,456 lux, a 180% increase over the halogen baseline. The photograph shows a defined central hotspot and strong forward reach.
Glare measured 380 lux. It was not among the lowest glare readings in the chart, although it was not an outlier for a brighter reflector LED. Consider it together with the 2/5 beam-pattern rating, the output gain, and the optics and aim of the housing.
Projector headlight performance
In our projector test, the Ultra 3 produced strong output with a clean cutoff, useful width, and a concentrated hotspot.

Projector headlights are less forgiving of an LED's position, width, and focus. When those relationships are wrong, the beam can lose intensity, scatter light, or distort the cutoff.
We measured 830 lux on low beam, a 261% improvement over the stock-halogen baseline, and 910 lux on high beam, a 106% improvement. The strong result in this second housing shows that the Ultra 3's measured performance was not limited to our reflector test.
Beam control was one of the stronger parts of the projector result. The cutoff stayed clean, the width remained useful, and the hotspot was concentrated without becoming visibly disorganized in the photographs.
Output, color, and stability
We measured total light output, color temperature, and the change in output as the bulbs warmed up.
GTR Lighting Ultra Series 3 Kelvin
GTR Lighting Ultra Series 3 lumens
We measured 5100K, a clean white color without a heavy blue tint. That is useful context because a bluer-looking bulb is not necessarily better on wet pavement, in rain, or during a long night drive.
Total output measured 4,788 lumens per bulb, or 9,576 lumens per pair. That is a 202% increase over the traditional-halogen result used for this test.
From cold startup to 30 minutes, output dropped 15.7%. Most of that change happened during the initial warm-up: from two minutes to 30 minutes, output dropped only 2.8%. That warmed-up figure is the more useful indication of stability, and the Ultra 3 held its output well after the first two minutes.
Installation and cooling
The internal driver simplifies the package, but the 43.1-watt draw and rear fan make electrical compatibility and physical clearance important checks before ordering.
Per-bulb draw
The Ultra 3's 43.1-watt-per-bulb result is compared with 54 LED kits recorded from 11.9 to 95.6 watts per bulb and the 53-watt halogen reference.
30-min temp
The Ultra 3's 130-degree result is compared with 54 LED kits recorded from 80 to 166 degrees Fahrenheit. The visual scale extends to the 525-degree halogen reference.
Fan noise
The Ultra 3's 58-decibel result is compared with 54 LED kits, including 11 fanless products and fan measurements up to 71 decibels. The halogen reference has no cooling fan.
Physical size and fit
The bulb measures 34 mm at its widest point, 25 mm from the base to the rear, and 51 mm across the diode-handle dimension. The H7 version is listed as rotatable in 1-degree increments. There is no separate external driver module, but the rear fan and heat sink still need room inside or behind the housing.
GTR Lighting uses TST 7045 diodes, with three emitters per side and six per bulb in a flat orientation. The chart lists the available bulb sizes, but a matching size alone does not confirm fitment. Check bulb type, seating, rear clearance, and dust-cover space for the selected vehicle before ordering.
Power draw and cooling
We measured 43.1 watts per bulb on the test bench. The 86.2-watt pair total is derived from that per-bulb measurement.
After 30 minutes, running temperature measured approximately 130°F / 54°C. The rear heat sink and active fan shown here manage that heat. This short bench test is not a long-term durability result.
Noise and electronics
We measured 58 dB at the fan on the bench, where it was audible when listening for it. We did not record cabin noise after installation, so its in-vehicle sound level remains unknown.
Our reference test produced no warning lights or flicker, and the chart labels the kit CANBUS-friendly. Vehicle monitoring systems vary, so that is a useful bench result rather than a compatibility guarantee. DRL and high-beam dimming behavior remain N/A, as does radio-frequency interference, because those checks are unfinished or unconfirmed.
Warranty and long-term testing
Coverage
Among 54 LED kits, 25 list a one-year warranty, 19 list two years, 4 list three years, and 6—including the Ultra 3—list lifetime coverage. Warranty is not recorded for the 83 products in the halogen chart. Listed coverage is not a measured durability result.
The product is listed with a limited lifetime warranty. That is manufacturer or seller coverage, not evidence of measured lifespan; confirm the current terms, exclusions, and claim process before ordering.
Long-term lifespan remains N/A because full runtime testing is not complete. The 30-minute temperature and stability results, our experience with earlier products, and the warranty do not replace a completed durability test.
Should you buy it?
Buy the Ultra 3 if you want a premium LED kit that performed strongly in both of our reference housings and you value its clean 5100K color, stable warmed-up output, and well-finished internal-driver hardware.
If the Ultra 3 performs like the Ultra Series 2 it replaced, we expect these bulbs are likely to last for the remaining life of many vehicles. The Ultra 2 maintained more than 75% output beyond 5,000 hours in our testing, and the Ultra 3 continues to run strongly on the bench so far. The Ultra 3's own long-term test is still in progress, so that expectation is conditional—not a completed lifespan result or guarantee.
The main tradeoff is the roughly $259 price. The 2/5 reflector beam-pattern rating and 380-lux glare result also make housing choice and careful aiming important, while the 43.1-watt-per-bulb draw and rear fan require electrical and clearance checks. Consider another option if budget is the priority, or if you need confirmed exact-vehicle fitment, DRL or RFI behavior, or completed lifespan testing before ordering.
If those tradeoffs work for your vehicle, check the current price or compare the test results before deciding.
