An Audette Collection/Daniel Stern Exclusive
The previous king of the mountain H4 halogen bulbs were the Vosla H4 +1901. These have just been dethroned by these. Manufactured in Germany (one of the few H4 halogen bulbs not made in Asia), deliver 250% more illumination than a standard 60w/55w H4 bulb. That's 190% brighter with no increase in current draw or heat generated. As a result they don't require the installation of a relay kit as is required by the standard 100/55w H4 bulbs. There is one compromise - they don't last as long as standard H4 bulbs. These are a simple plug n' play replacement for your current H4 bulbs.
Built Specifically for Automotive Lighting Expert and AC Chief Consultant Daniel Stern: His Analysis
JA Note: Candid as always. Daniel is a person of high integrity, both professionally and personally, and he is always open, honest and candid.
Any of the bulbs claiming to produce "extra white" light (or super white, hyper white, platinum white, metal white, xenon white, etc) is best avoided. It doesn't matter whose name is on the bulb—Sylvania SilverStar/Ultra or ZxE, Philips BlueVision or CrystalVision, Wagner TruView, anything from PIAA or Hoen,, Nokya, Polarg, Osram NightBreaker, etc.—all the same scam. The blue-tinted glass changes the light colour a little (does not make it "whiter"; that is not a thing), but in so doing, it blocks light that would reach the road if the glass weren't tinted, so they give you _less_ light than ordinary bulbs (not more). Contrary to marketing claims which put their toes right on the edge of the line separating mere fibs from false and misleading advertising, there's nothing about the tinted light that improves your ability to see—the opposite is true (less light = less seeing, no matter about the tint). Sylvania got spanked to the tune of thirty million(!) dollars for false and misleading "upgrade" claims for Silver Star bulbs — and those are among the least-bad of an overall bad product category, so the math kind of does itself.
Beyond that: these bulbs, with untinted glass, are a further evolution beyond the previous +190: higher filament luminance and tighter 5-axis filament-placement precision, for punchier, better-focused headlight beams. All in a spec-wattage bulb.
#2: Please do not use LED bulbs in reflector headlights like these bulbs are designed for. You may have noted that we do not sell individual LED headlight bulbs for that reason. If they worked properly we would sell them. Click here for the details on why they are a disaster from Daniel Stern.
