Best Brightest D1S Bulbs (Xenon HID, LED Headlight Bulb): The Definitive Guide

Features and rating of xenon d1s lamps

Xenon lamp D1S is used as a standard in the vast majority of cars where the manufacturer provides xenon light. This light is designed for installation in headlights with lens optics, unlike the D1R lamps designed for reflector headlights.

Full deciphering of the marking will look as follows:

• D – xenon;
• 1 – development number, modification;
• S – for headlights with lens optics.

Structurally, the device is made in the form of a narrow bulb, equipped with a rather massive original base.

The letter “D” in Xenon D1R stands for Discharge and indicates that it is a gas discharge lamp. The number “1” indicates that this is the first development version of the Xenon D1R type. The letter “R” indicates the type of glass bulb. A Xenon D1R socket is suitable for Xenon bulbs for headlights with reflector system. In contrast to the paraboloid headlamp, there is no diffusing lens. The entire illumination is based on a special design of the reflector, which allows cover lenses of clear glass or scratch-resistant plastic. The whole reflector is divided into partial segments by a computer control. This allows an optimal alignment and illumination of the roadway, because the light is always reflected downwards.

Brightness

The brightness of most xenon bulbs is 3,200 lumens. This is significantly brighter than most lamps at home. For comparison, 250 to 300 lumens per square foot is recommended in bathrooms, kitchens, and study rooms. A 100-watt incandescent lamp shines at 1,380 lumens. Caution: Immediately after installing xenon bulbs, it takes about 15 hours of operation for them to develop their full luminosity. In technical jargon, this means that the xenon burners have to burn-in.

Light color

Light color, which is measured in Kelvin, is also visible: the bluer the light, the higher the Kelvin value.

Light color: The color scale ranges from red to blue, with yellow, white, and turquoise in between. Warm white light, used in living spaces, is less than 3,300 Kelvin. Universal white light is on a scale between 3,300 and 5,300 Kelvin. These values are recommended for study rooms, bathrooms, and kitchens. Daylight white light starts at 5,300 Kelvin. From 6,000 Kelvin, the light becomes bluish and is suitable for utility rooms. There are also xenon burners with a bluish light color. If we are talking about blue xenon burners, the light color is above 6,000 Kelvin.

What distinguishes xenon burners from halogen or LED lights in tests?

Halogen bulbs, LED bulbs and xenon bulbs are the three front runners installed as headlights in vehicles. The function of xenon lamps has now been explained in detail, culminating in a number of benefits, such as brighter light similar to daylight, sleeker design, greater range, and optimal road illumination. Higher costs and the problem that more wiper water will be needed to prevent stray light are the manageable disadvantages of xenon burners. Xenon bulbs score particularly well in the service life category.

For comparison – these are the advantages and disadvantages of halogen lamps.

Advantages:

• inexpensive and usually part of the basic equipment;
• easy to maintain and service;
• pleasant light.

Disadvantages:

• low range;
• lack of brightness.

For comparison – these are the advantages and disadvantages of LED lamps:

Advantages:

• attractive design;
• light similar to daylight;
• good lifetime.

Disadvantages: 

• not part of the standard equipment;
• not individually replaceable.
