The term OEF-A typically refers to the phase of the War in Afghanistan from 2001 to 2014. Other operations, such as the Georgia Train and Equip Program, are only loosely or nominally connected, such as through government funding vehicles. All the operations, however, have a focus on counterterrorism activities.
PAR 38 is a type of halogen or LED light bulb. There are two definitions for the acronym PAR, but both describe the same thing. One is parabolic aluminized reflector.The other is pressed-glass aluminized reflector. In PAR 38 lighting, both the lens and reflector are internal parts of the lamp.lso, PAR 38 bulbs can be purchased in WFL, which is a wide-flood beam spread. These are available in SP, or spot, and FL, or flood, as well. The two types of floodlights are the ones best for lighting a large area with one bulb. PAR 38 bulbs come in wattages from 53 watts to 250 watts.
The IR (or sometimes HIR) in the description code means âinfraredâ, as you might have guessed, but it does not mean these bulbs are for heat lamp applications. The IR refers to a coating on the halogen capsule which is located inside the reflector of PAR or MR halogen light bulbs.This diagram shows the capsule inside an MR16 reflector. Several layers of durable, thin interference film are added to the capsule wall.n the second example, assume you currently use a number of 50MR16/FL40 bulbs. To cut energy costs without sacrificing the quality of the light, select the lower wattage, IR version of the same bulb, 37MR16/IR/FL40. and get the same light output using about 30% less energy.
