There are, no doubt, political aspects to adopting European standards as well. These results could be adopted in the UK, but there is a question mark over whether the results for a left-hand-drive car are also valid for UK cars. ![]() The process is tortuous because each car needs to be tested both electronically and mechanically in order to ensure they comply with the regulations and the results approved by the various legal authorities. Other countries are in the process of accepting them. These lights replace halogen headlights with. In Germany 70 per cent of the car parc can use them, and half in France. The SEALIGHT 9005/HB3 H11/H9 14000LM LED Bulbs Combo comes with four LED projector headlight bulbs, two high and two low, as well as a wiring harness. They are illegal for use in the UK because the ECE spec requires a filament bulb, but in some European countries on some cars that’s not the case. Best Halo Headlights Reviews & Recommendations Best Overall Aukmak LED Halo Ring Angel Eyes Check Latest Price The Aukmak seven-inch LED halo headlights are an upgrade from standard. You don’t have to search online for long for an H7 bulb before you are offered a retrofit LED version. ![]() Once fitted into the headlight, performance was woeful, with faulty geometry on one bulb. On initial start, both bulbs smoked significantly and would likely wreck any headlamp reflector. This Aceparts lamp was tested to see how much you needed to compromise performance to get that blue/white gas discharge look in the headlamp. The results were converted to percentages to get an overall ranking. We also checked the bulbs for ECE R112 beam compliance plus maximum output and geometry. SYLVANIA - H11 (64211) SilverStar zXe GOLD High Performance Halogen Headlight Bulb - Headlight & Fog Light, Bright White Output, Best HID Alternative, Xenon Charged Technology (Contains 2 Bulbs) View on Amazon. A website touting the Sylvania SilverStar headlight bulb says it provides up to 30 percent greater visibility down the road. To balance this adjustment-dependent rating, we measured the area at more than 30 lux, beam length above 3 lux and the maximum brightness. ![]() The results were combined to give our figure of merit (FOM). We measured light at 50 and 75 metres ahead of our test Volkswagen Passat headlamp on low beam. How we tested themĮvery bulb was put through our standard set of assessments. We also looked at where the tech is going by assessing the latest LED replacements for the ageing halogen systems. With the very limited number of firms capable of operating at the highest level, we also looked at a standard bulb to see how far the tech has come and the compromises needed to get that xenon white/blue look in your headlamps. But the proof was driving back from Idyllwild last week at midnight on a dark mountain highway with no lighting: Those Phillips bulbs are more than adequate and they measure just over 3400 Kelvin on a Sekonic C700U color meter.So which has embraced the latest technology the best? We enlisted the help of Philips’ light tunnel in Aachen, Germany, via Microsoft Teams to find out. I was pretty sure they looked the same visually but by actual measurement they really were. Everything within 1/10th of an f/stop between the two. Projected on my garage door and then measured with a Minolta Flashmeter 6 using the incidence metering mode in various areas of both beams and there was not a meaningful difference between the two. So I had one Phillips H11 and on Phillips H9. Now remember that the H9 is *basically* the same as an H11 but 65W vs 55W for the H11. I was curious about running H9's so I bought a couple (same bulb as your high beam), ground down the upper tab and installed just one. Sure, it's raises the Kelvin but also considerably lowers the lumens as well. ![]() Just make sure you don't get bulbs with the blue coating over the entire capsule. Won't last as long but easy to change out.
