The Lumibright XT1 was a new product when this review was written, and we jumped at the opportunity to get it into the lab after seeing good feedback. In the original test period, it landed near the top in multiple headlight categories.

Lumibright provided the sample for testing, but did not pay for the review or control the result. The article was written from the measurements, not from marketing copy, and the data was strong enough to make the XT1 a standout in the older BulbFacts test group.

The XT1 was a smaller LED product with a familiar general shape, so we did not know exactly what to expect when testing started. The results were much stronger than its size suggested.

Reflector test

Reflector Style Headlight Test Results

The XT1 produced huge reflector output in the original test setup while keeping an unusually clean low-beam pattern.

In the version 1.0 reflector test, output was truly astonishing at 5950 lux in a low-beam reflector headlight. That compared with 1610 lux for a standard halogen bulb and 2240 lux for the top halogen bulb in that test set.

That worked out to about 3.7 times brighter than stock halogen, placing the XT1 near the very top of the reflector test category at the time of the review.

The best part was the beam pattern. In the old scoring format, the XT1 earned a perfect 5.0 low-beam reflector pattern rating. The source article noted no additional glare issue in the headlight test, which was rare for a high-output LED.

High beam also performed well at 7110 lux, roughly doubling the standard halogen result in the original test context. The improvement was not just output; the whiter color and instant-on behavior also helped make it feel like a serious upgrade.

Projector test

Projector Style Headlight Test Results

Projector performance was one of the biggest reasons the XT1 stood out in the original review.

For weak halogen projector headlights, the XT1 was one of the strongest LED products in the original test set. It measured 3320 lux in the low-beam projector hotspot, compared with 876 lux for halogen in the same projector bench.

That was nearly 3.8 times more output, and the source article noted that it tied the popular Hikari Ultra while offering a whiter color temperature.

For a dedicated high-beam projector or bi-halogen setup, the XT1 measured 5000 lux compared with 3200 lux from the halogen bulb, roughly a 1.5x increase.

There were better options for some high-beam projector applications, but as a low-beam projector upgrade in the version 1.0 test group, the XT1 was one of the strongest performers.

Output and color

Kelvin, Lumens, And Realistic Output Claims

The XT1's measured output was close to its claim, which was refreshing compared with many inflated LED listings.

Lumen output testing

The color temperature tested right at 5950K, which is a clean white with a slight cool tint. It was very close to the claimed 6000K rating.

Lumens are a secondary measurement compared with beam lux, but they still help explain total output. Many Amazon and eBay products claim huge numbers that do not match reality, while premium brands tend to publish more believable figures.

The XT1 claimed 2850 lumens per bulb, and we measured 3030 lumens per bulb, or 6060 lumens per kit, after 2 minutes stable with passive cooling. That is unusually close to the claim and helped reinforce the quality of the product.

Hardware notes

LED Chips, Power, CANBUS, Temperature, And Noise

The XT1 paired strong output with modest power draw, reasonable fan noise, and good compatibility results.

Lumibright did not advertise the exact LED brand in the original material, but when we reached out, they stated that a top-tier Philips diode was used. Based on the concentrated beam and high output, that claim fit the test behavior.

Power consumption measured 25.1 watts per bulb, roughly half of many halogen main-beam bulbs. The heat sink reached about 93°F / 34°C, much cooler than a halogen bulb around 160°F.

Fan noise measured 65 dB. You may hear vibration if the bulbs are powered with the vehicle off, but once installed in the front of the car, it should not be a meaningful issue.

CANBUS compatibility was a strong point. The XT1 passed the CANBUS checks used in the original review, and no additional anti-flicker or decoder module was expected for most tested systems.

Fitment and value

DRL, Clocking, Warranty, Cost, And Final Thoughts

The XT1 had unusually strong adjustability for its time, plus a 3-year warranty that helped support the premium positioning.

DRL behavior was not universal. On a standard line, the XT1 cut out at 7.0 volts or less, so some high-beam DRL systems might not dim correctly. Low-beam DRL behavior was expected to be less problematic in the original article.

Clocking was a major fitment advantage. The XT1 allowed adjustment in 10-degree increments, which was better than many products at the time. That matters because the diodes should normally face left and right in a 9-and-3 position, then be adjusted to match the original halogen cutoff.

The XT1 included a 3-year warranty, better than the standard one-year coverage common in many LED listings. The source article expected good life from the product due to the premium construction, though no long-term lifespan rating was listed.

At the time of the review, the XT1 was one of the brightest products in the BulbFacts test group and ranked near the top depending on application. Today, it should be treated as a legacy review and compared against the current chart before buying.
