Photometrics combined with candlepower determine the lamps performance (luminosity). Photometrics is how light is distributed and candlepower is the amount of light emitted from the bulb. Photometrics is determined by flutes behind the lens or mirrors on the reflector.
Distributed light patterns can go from a pencil beam to a wide flood. A smooth parabolic reflector with a clear lens produces a pencil beam. A fluted lens produces a flood light due to prisms on the inside of the lamp that bend or refract the light. Refracted light is yellowed, reducing the light's brightness.
Modern technology lamps have clear lenses with mirrored reflectors. This produces a dense light pattern with whiter light that reaches farther down the road than a fluted lens lamp.
H4 bulbs come in Halogen (Iodine) or Xenon (an inert gas). Xenon is about 30% brighter than iodine. Some bulbs have dichroic mirrors (colors) to change the wavelength of light, making the road more visible.
Others have blue filters to make them look like H.I.D. (mentioned below). Filters, like sunglasses, reduce the amount of light emitted from the bulb, making it dimmer. Blue lights on some cars are H.I.D. (High Intensity Discharge), which is an arc lamp, deriving its light from an arc jumping from one electrode to the other, inside a quartz glass tube filled with xenon gas and metallic salts.
Most bulbs are incandescent lights and have a thin, wound filament, that heats up and glows inside a bulb or sealed beam, filled with various gasses. H.I.D. is 3 to 4 times brighter than iodine and draws less power (wattage) than incandescent lamps.

King of the Road!
Headwinds, the leader in custom headlights, introduces their new Vector Nacelle Bezel for the Road King and any FLH! This easy-to-install, tapered bezel follows the curve of the stock nacelle for a continuous line and a stunning look! Fully machined from 6061-T6 aluminum, there is not a split-gap or clamp-screw at the bottom like other bezels have.
Available chrome, polished, anodized or as machined. Made in the USA. Contact Headwinds at 626-359-8044 or email at headwinds@headwinds.com. See their website at www.headwinds.com.
