Suppose you are riding on any cars or trucks manufactured with a sealed beam 4×6″ rectangular headlights. Then there is a possibility you might go for an upgrade to use them during the dark hours of the day.

Changing the model to LED headlights helps you add more style, performance, and safety to your vehicle. The commonly used 4×6″ sealed beam consists of two types.

If the before-mentioned part numbers match the original headlights (new version – 4×6″ LED headlights), that would be one of the best options.

This post will elaborate on specifications and details on 4×6 inch headlights. Also, compare the original stock bulbs to the beam pattern and the output.

The most impressive part is that New Vision made the LED headlight with the latest line added. The Offroad 4×6″ LED headlight turns out to be the perfect addition.

What’s more exciting about these headlights? It is recognized among the least lot with the dual-beam feature worldwide. Both high/low beams within a single headlight.

While comparing the others 4×6″ LED headlights, you may come across similar characteristics about the vortex line and other headlights as well.

What are the headlight features?

• 15 x 3w LEDs
• Standard OEM 3-blade connector
• Completely sealed electronic
• Provide the greatest visibility

Compared to an advertised lumen, lux (25 feet), and beam pattern.

Around 25 feet from a wall, we left the LED headlights, then to measure the lux ( the brightest point inside the beam pattern), we used a digital lux meter.

You may question us over the difference between lux and lumen and why measuring the lux?

Therefore to get a vivid picture of the performance of a headlight. Let’s clarify the three types of equipment: lumen, lux, and beam pattern.

Lumen

The measurement of light is created in the headlight. Likewise, the amount of light depends on the amount of lumens present. Yet if all these lights do not focus on the road, their usage goes in vain.

Similarly, a massive amount of light does not focus on the beam pattern. Then the headlight would not be used for its exact purpose.

Lux

Then comes the lux measurement into action. While observing the beam light from 25 feet, we identified the single spotlight ( most focused) and measured it.

Lux measures the light (usable amount) at a certain distance. Here we calculated the beam pattern( at 25 feet) to identify the amount of light that would direct in front of the vehicle.

We marked a sign at 100 yards by measuring the road in 10-yard increments. So the farthest sign is on the 100-yard placement. Also, we observed through a camera, setting on a tripod at F5.0, 1/2, IOS 1600.

We witnessed the stock 4×6″ beam light at low and high beams in such placements. We used two headlights parallelly in a vehicle. Measured lux indoors ( 25 feet- against a wall), and we identified that

• Single headlight – 650 lux (low beam)
• Single headline – 650 lux (high beam)

We kept two parallel headlights to check how the vehicle operated within the same setup. We held the low beam at 1,210 lux and the high beam at 1,140.

Again both high/low beams at 1,850 lux. As a result, 4×6 sealed beam LED headlight created 2,700 raw lumens.
