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 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 Sylvania Metalarc PRO-TECH metal halide lamps were created to fill the need for a safe light source for applications where a protective lens on the metal halide fixture was either impractical or detrimental to fixture design. The Metalarc PRO-TECH lamp design enhances safety in open or enclosed fixtures and includes a shroud around the arc tube and, in some cases, a thicker walled outer jacket. In addition, these lamps have a reduction in UV output compared to standard
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. 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.
With the benefit of open fixtures, these high output Sylvania MP400 Metalarc PRO-TECH lamps are ideal for higher ceiling applications where enclosed fixtures might previously have been necessary. The use of open fixtures means more light output over life and lower maintenance costs because there are no lenses to gather dirt and dust, thus extending lamp replacement procedures.
If you currently use GE MVR400 Multi-Vapor bulbs or Philips Switch Start Metal Halide MH400 bulbs, you should consider an upgrade to the Sylvania Metalarc line of products. Besides having the most complete line of products, Sylvania puts more energy and effort into quality control and it shows in the excellence of their products. You will have far fewer defective bulbs out-of-the-box and will, on average, get longer life from your bulbs than GE or Philips, a great benefit for busy business people or contractors.
