Sometimes looking at the best sellers in different categories of goods and services can help you learn what the best options for your application are. When it comes to finding very bright, highly efficient, high light quality, long life light bulbs for your office, production facility, warehouse, or other large buildings, most people choose M400 Sylvania metal halide light bulbs. The brand chosen most often is Sylvania Metalarc. Bulbs made by other manufacturers might be referred to as Multi-Vapor. While the technical term for the bulb is M400/U, they are simply referred to as 400 watt Metal Halide bulbs or 400 watt Metalarc bulbs. These high-octane bulbs really pack a punch and offer users a bright white light to work under. The part number for this 400 watt version is Sylvania 64490.
Have you ever driven up to an intersection and seen two different gas stations at the corner? One station has a yellow or orange tint to its light; the other has bright white color. All things being equal, most people will choose the station with the bright white light. Chances are the white light that you saw was provided by a Sylvania metal halide light bulb. This one simple choice can mean a lot to a business owner who is fighting for every customer possible. In another scenario, imagine the new warehouse facility you are working in has Sylvania 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. In general, they are used in places high above ground level, as they emit so much light, it would not be practical to have them close to eye level. Gymanasium lighting and parking lot lighting are really common applications for this bulb.
The most recognizable physical feature of this bulb is its unique shape. It is a bulb-within-a-bulb, meaning that the smaller bulb, which is located where the filament of a light bulb typically is, 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 certain elements of the bulb and producing the visible light. Sylvania metal halide lighting contains some really excellent 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. The bulb is offered in a clear glass design standard and is available in a coated design too, for an even light spread.
You might have heard that these types of light bulbs show color very poorly. Well, in the case of the Sylvania Metalarc 400 watt light bulb, that is just not the case. The CRI of the bulb is 70, which means the color quality of this Sylvania metal halide bulb is comparable to normal fluorescent lighting. The bottom line is you wont have to sacrifice quality and performance to save money each month on energy. The M400/U truly gives you the best of both worlds.
If you currently use GE MVR400 Multi-Vapor bulbs or Philips Switch Start Metal Halide MH400 bulbs, you would be a perfect candidate to upgrade to the Sylvania Metalarc line of products. Sylvania puts more energy and effort into quality control and it shows in the excellence of their products. Combine that quality with our high level of service, and youve got a really great lighting solution.
