In the modern lighting area, more people use Sylvania M400 metal halide light bulbs when it comes to finding very bright, highly efficient, long life, high light quality light bulbs for their office lighting, warehouse lighting, or other facility lighting. Clearly the Metalarc bulb series is the most popular due to Sylvanias attention to detail on product quality, both in durability and light quality. Keep in mind, the GE metal halide bulbs and Philips metal halide bulbs might be referred to as Multi-Vapor. While the technical term for the bulb is M400/U/BT28, they are simply referred to as 400 watt Metal Halide bulbs or 400 watt Sylvania Metalarc light bulbs. The BT28 in this bulb description indicates that the glass shape of the bulb is smaller than a normal M400; 28 eights of an inch. These powerful light bulbs really emit a large amount of light and offer users a clean white light for a variety of needs. If you need parking lot lights or airfield light bulbs, you are in the right place!

Imagine seeing two banks on a road one evening. One bank has yellow/orange tinted light and one has bright white light. All things being equal, most people will choose the place with the bright white light as the light makes people feel safer by providing a clearly lit area. Chances are the white light that you saw was provided by a Sylvania Metal Halide light bulb. In another scenario, imagine the new production facility you are working in has metal halide lighting. The paperwork you use will be clear and visible, the many products on the shelf will be easier to see, and potential hazards will be noticeable, potentially avoiding accidents and increasing job satisfaction.

The most recognizable physical feature of this bulb is its unique shape. Inside the large glass envelope you will see a smaller tube located where the filament of an incandescent light bulb typically is. It creates the light, while the surrounding shell serves to keep the special mix of inert gasses surrounding the center tube. The bulb produces light by allowing energy to pass through the arc tube, heating up special elements of the bulb and producing the visible light and heat byproduct. Metal Halide lighting contains some really efficient technology designed to provide the highest light output with the lowest possible energy consumption. This model has a large base, called a mogul base or E39 base and the small bulb shape will allow this model to fit into places the standard high intensity discharge lighting would not. These bulbs are offered as clear light bulbs as a standard and are also available as coated light bulbs for an even light spread.

It is a common misconception that these types of light bulbs show color very poorly. Well, in the case of the Sylvania Metalarc 400 watt light bulbs, it is just not the case. The CRI of the bulb is 70, which means the color quality of this Metal Halide bulb is comparable to normal fluorescent lighting. In many modern facilities, this is the only type of light bulb used at all, thanks to its white color and massive floor coverage. The bottom line is you wont have to sacrifice quality and performance to save money each month on energy. The Sylvania M400/U/BT28 truly gives you the best of both worlds.
