Why LED car lamps are better than halogen ones: test

In automotive parts stores, you can easily find kits for quickly replacing halogen lamps with LED ones that do not require additional modifications to the car or a trip to a car service. To test how good the diode bulbs are, we test them on the 1996 Toyota 4Runner SUV, which is equipped with halogen headlights with H4 incandescent bulbs.

The halogen lamp is designed so that it emits light from the bulb in all directions, and in our case a diode bulb only four small dots emit light. In addition, LED lamps are necessarily equipped with heat sink radiators.

From a practical point of view, diode lamps are very bright and theoretically should last a very long time, and in addition, they consume several times less energy than ordinary "halogens". Installing the finished kit in the old headlights, which is now called the fashionable word "retrofit", is quite simple - you only need good access to the headlights from the engine compartment. Just remember to check the headlamp adjustment after that.

Here is the difference between the lamps with the driver’s eyes:

Looking at the photo, it seems that LED bulbs are superior to halogen in everything, but if you compare them with your own eyes, the "halogens" still shine a little further, which may be more important than the increased brightness of close-range lighting. For oncoming cars, diode lamps also look much brighter, and due to the lack of a clear cut-off line in the reflex headlights, they can significantly blind them.

Verdict? LED lamps are good, but hardly suitable as a quick replacement for halogen bulbs. But they are perfect for use in lighting fixtures, where brightness is more important than the range of illumination - for example, in brake lights or direction indicators. As for the headlamps, the good old "halogens" are too early to send to rest.
