Factors to Consider When Choosing a Bi-LED Projector Lens
Bi-LED projector lenses come in different sizes indicated in inches. Common options include the 3-inch, 2.5-inch, and 1.8-inch.
The bigger projector lenses will easily fit in cars with large headlights. However, you can still install a smaller bi-led lens if you add a large shroud.
Small projector lenses may be the only option for a car with small headlights. However, some will handle a larger lens with a little bit of retrofitting.
Type of Reflector Bowl
Bi-LED projector lenses can have either metal or plastic reflector bowls. The reflector bowl material was once a major concern because it could become damaged by the heat produced by the bulb.
The quality of plastic reflector bowls has improved with more heat-resistant material being used. A typical LED bulb also produces a lot less heat than a halogen or HID bulb.
Wattage
Projector headlights have different power requirements. Some are rated at 45 watts while others are rated as high as 140 watts.
Usually, the higher the wattage the brighter the bulb should be, but this isn’t always the case. High wattage results in more heat which can shorten the lifespan of the headlight and make the LEDs less bright. Additionally, the brightest LEDs can be hampered by low-quality lenses.
Manufacturers can use lumen or lux to describe how much light their headlights produce. Lumen is a measure of the light output at the source, i.e., the LED, while Lux is a measure of how much light is cast onto a surface from the source.
Lux is an important parameter because it factors distance and other factors that can limit how much light will be cast onto the road.
Depth and Width
Depth is a measure of how far ahead the light from the headlight will be projected and width is a measure of how well the headlight illuminates the sides of the road. Both of these are important, especially when the sides of the road are not well-lit, e.g., country roads.
Compatibility and Ease of Installation
Depth is a measure of how far ahead the light from the headlight will be projected and width is a measure of how well the headlight illuminates the sides of the road. Both of these are important, especially when the sides of the road are not well-lit, e.g., country roads.
For easy installation, try and find Bi-LED projector lenses that are made for your vehicle type. Unfortunately, this isn’t always an option.
Quality and Price
Last, but not least, it’s important to consider the quality and price of the Bi-LED projector lenses before making a purchase. A high price doesn’t always mean great quality but don’t go looking for the cheapest products either.
