LED Corn Bulbs - Hazardous Location - LED Metal Halide Retrofit Lamps

Hazardous Location LED Corn Bulbs are designed to replace metal halide bulbs in Class I, Division 2 light fixtures. 


Class 1: A hazardous location in which flammable gases or vapors may be present in the air in sufficient quantities to be explosive or ignitable, such as petroleum refineries, aircraft hangars, dry cleaning plants, utility gas plants or storage areas for liquified petroleum or natural gas, and spray finishing areas.

Division 2
Abnormal condition, for example: Closed storage drums containing flammable liquids in an inside storage room would not normally allow the hazardous vapors to escape into the atmosphere. But if one of the containers is leaking, you've got an abnormal condition.

The gases and vapors of Class I locations are broken into four groups by the Code: A, B, C, and D. These materials are grouped according to the ignition temperature of the substance, its explosion pressure, and other flammable characteristics.
Group A: The only substance in Group A is acetylene because it is a gas with extremely high explosion pressures. 
Group B: This group includes hydrogen and other materials with similar characteristics. 
Group C & D: The most usual Class I groups. They comprise the greatest percentage of all Class I hazardous locations. Found in Group D are many of the most common flammable substances such as butane, gasoline, natural gas and propane.
