Rough Service

Unassigned

Write a Review of This Product
Rough service lamps differ in two key aspects from regular incandescent lamps.  First, they use a blend of krypton, argon and neon gas to extend the lamp life.  This is accomplished by the introduction of heavier gasses, primarily krypton and argon, which slow the rate at which the filament decays during operation.  Secondly, they use eight filament support wires as opposed to the traditional four support wires.  These additional support wires insulate the lamp from thermal shock and external vibration which often cause premature lamp failure.  Rough service lamps are used heavily in the construction industry and industrial applications.  The wattage range of these lamps is from 25 watt to 300 watt in sizes from A 19 to PS 25.  The lamp envelope is finished in frosted or clear.  Rough service lamps also form the core of the safety coated product line.
