Which headlight bulb test

Lux test results are per bulb each taken at exactly 5 minutes of runtime with ambient cooling. Result is taken at exactly 5 minutes of runtime with ambient cooling. The HID charts are sorted by best star rating in each product category top to bottom. Test Platform 1. Test Platform 2. Beam images taken with the same camera exposure settings, color is near true to life but will vary depending on your viewing screen. Color shown is tested using a kelvin meter pointed at headlights output against a white test wall.

Kelvin rating of k has a yellow incandescent tint, k is pure white, k has a blue tint. We had to remove it to allow for responsive data flow. We appreciate your patience in the meantime. Additional tests are planned for future results. If you have any requests or products you would like to see tested, please feel free to contact us!

LEDs are simply semiconductors with no wear-and-tear parts, which should — in theory — last the lifetime of the car. Not only can they look spectacular but they have some clear benefits. The bright light that they produce is also much closer to daylight, giving less glare and making them less likely to dazzle drivers in oncoming traffic. They are now quite common on family and mainstream cars, either as a factory-fitted option or an aftermarket upgrade. Bear in mind that, while xenon conversion kits can be bought very cheaply, only complete units including self-levelling and cleaning systems are road-legal in the UK and will pass an MoT.

Xenon bulbs, however, have a longer lifespan than halogen bulbs, and are claimed to last 10 years before needing replacement. There are a number of ways they can be upgraded, however.

We also tested a popular online LED bulb, but while the beam length was similar, there were significant amounts of illegal glare for oncoming drivers. Its 92 per cent beam rating was bettered by most of our halogen lamps, too.

Previous performances from Twenty20, which is a range stocked by online retailer Auto Bulbs Direct, gave no indication that the Daylight would be a potential test winner. With Megalight branding on the base plate, we suspect that this is another bulb to come out of the former GE factory in Budapest.

Consistency was good, with two top-performing bulbs helping it to take the FOM test by a big margin, while it won the beam length test with a narrower lead. A shock win, but well deserved. Buy now from Auto Bulbs Direct. It takes the runner-up spot but by a narrower margin over rivals than the promised performance increase might suggest. It topped the bright spot test, had the second-best FOM and a beam length of metres, but overall brightness saw it rank sixth in a close-run test, which denied it a debut win.

Our test, which measures the beam down to 30 lumens, saw an average length just shy of 94 metres, which put Osram sixth. It topped the beam brightness test, though, which helped it to secure a podium. In the tunnel it had a bright hotspot close to the metre mark which helped it to fifth in the FOM test, plus its beam length was just over 94m.

Buy now from Halfords. To the naked eye in the tunnel they were difficult to separate, with both having good hotspots and sharp cut-off lines. They had similar brightness results and a beam length of just over 94 metres, too.
