SYLVANIA H11 SilverStar Ultra Halogen Headlight Bulbs, High-Performance High/Low-Beam and Fog-Light Replacement Bulbs While I'm confident that both have been uttered with the best of intentions, I'm hoping that my observations (as someone with nearly half a century of A/V and lighting experience) may generate more light than heat. Maybe half the lifespan for safer operation is still worth the slight additional investment in both cash and effort. The "Xenon Effect" on the box definitely can NOT refer to the colour of these bulbs matching high-intensity discharge (HID) Xenon headlamps, as tungsten always burns more orange or yellow compared to HIDs or LEDs, so it can only be a reference to the halogen cycle I've outlined.

If you're after a very strong effect, choose OSRAM Xenarc Cool Blue Intense. With a colour temperature of up to 6000K, these bulbs achieve an ice white light with a slight blue tint for a strong, modern look. The SYLVANIA Silverstar high-performance halogen headlights feature a unique filament design that increases performance and durability and a lamp coating that contributes to a whiter light output. With a combination of white light and powerful beams, these innovative headlight bulbs allow you to see farther down the road during nighttime driving. As such, you'll have more time to respond to any road hazards that may arise. Firstly, how do we measure the whiteness of a bulb? Bulb manufacturers indicate the whiteness of their bulbs with a measurement known as colour temperature. This tells you whether the light produced is warm or cool. This is expressed in units called Kelvins (K).

There are no bad H4 bulbs here, but the RacingVision is our choice. For top D3S performance it has to be the Philips, and Ring is our standard choice. Don’t be tempted to save cash on unbranded alternatives. These LAWTOOLIGHT headlight bulbs provide excellent value for the money with their top-notch performance and incredible life span. Featuring vertically aligned LED components, they perfectly mimic the light pattern of the original halogen bulbs, resulting in a beam that spreads over a larger area. Also, they don't cause glare for oncoming vehicles. Equipped with a 15,000-RPM cooling fan, they have an impressive life span of 60,000 hours, which can greatly reduce your headlight bulb replacement interval. The Philips WhiteVision H7 produces a stylish, white beam with a colour temperature of up to 3700K for a premium driving experience. The whitest bulbs are those that measure around 5000K. This is a great balance between yellow and blue - bulbs at this colour temperature produce a light that is bright and clear. Some drivers prefer bulbs at 6000K, but these have a hint of blue that makes them slightly less bright than a bulb with a colour temperature of 5000K. There are tons of options out there if you’re shopping for the best H7 bulbs. But there are a few bulbs that stand out as the brightest.

The Philips WhiteVision range is the first to produce a road legal intense white light. Add WhiteVision bulbs to your car today for a premium driving experience with increased safety. Importantly, as with any engineering, we get "nothing for nothing" which means that their increase in light output comes at a "price" ...which, in this case, is a "burn time before failure" roughly half that of the trusty (but relatively orange) bulbs that came with my Hyundai. There are different headlight colours available on the market, not just your usual white. So, what colours are available and which are legal? Find out more here. White5000 bulbs also provide a more comfortable night time driving experience. They give better reflections from road markings and signs than standard bulbs, which emit a yellow light with a colour temperature of around 2700K. White5000s also put up 50% more light on the road than standard bulbs, helping you to see hazards more easily.No normal bulbs on the market no matter what they claim will give you xenon effect unless you upgrade to hid kit, or guess what.....actually have xenons!!
