#Hid vs halogen series

As discussed in our previous article, replacing an OEM halogen bulb with a WRONG aftermarket LED bulb could even reduce your visibility or blind other road users It is about the light colour and the light source pattern. Q: So, this has nothing to do with “halogens or LEDs” at all?Ī: Yes. Projector headlights have a more focused beam, thus improving visibility. Both LEDs and halogen headlights can exist in projector or reflector form.

Q: How does light source pattern affect penetration?Ī: By light source pattern we mean either reflector or projector type headlights. Since halogen light is generally warm/yellow, we perceive them to perform better in bad weather conditions.Īnother factor to consider is the light source pattern.

The drop in lux reading is lower.Įven the LED yellow light penetrates better than the LED white light. in %” column, you will see that yellow/warm light has better penetration. In this Youtube video, you can see just how different coloured lights penetrate fog. Red light has the longest wavelength, being the colour of choice for taillights and brake lights. In simpler terms, warmer light (yellow) penetrates better than cold light (blue). Warm light (yellow) has a longer wavelength than cold light (blue). Light with longer wavelength is not refracted as much as light with a shorter wavelength. Q: So, what makes for a good penetrating light?Īs it turns out, light penetration is affected by the wavelength. Water droplets could also refract light, causing them to loose effectiveness.įor better visibility, you would want a good penetrating light. Whether it is halogen or LED, the light will travel at an infinite distance, should there be nothing to block it (vacuum state). Since we do not live in a vacuum state, light intensity diminishes over distance due to particles in the air. Q: Does LED light travel further than halogen light?Ī: This is a matter of light penetration. LEDs use less energy to emit a brighter light. Q: LEDs are brighter than halogens, right?Ī: Yes.
