Explosion Proof Flood Light

Yes, class 1 div 2 require explosion proof. Class 1 div 2 is one of the hazardous locations classification which means the ignitable gas or vapor will produce not normally which is exactly a lower hazardous level, but it is still one kind of hazardous level of explosion proof whose classification intrinsically can be divided into higher level class 1 div 1, lower level class 1 div 2, higher level class 2 div 1, lower level class 1 div 2 and higher level class 3. Thus, class 1 div 2 require explosion proof no matter for what kind of electrical apparatus not limited to explosion proof lighting.

In simple, spotlight is a part of flood light, when you change the beam angle to a narrow one such as less than 45 degrees, you can call this light a spotlight, while on the contrary, if you adjust the beam angle to a wide one such as more than 45 degrees, you can call this light a floodlight. As for the application difference, you can use a spotlight to an important point like chemical test which have accurate lighting request for the lighting area scope, at the same time, you can use a floodlight for other points which only request rough lighting.

Area light is used for certain working plane or table which is normally a limited and fixed place to exact look for one processing procedure or workmanship, the distance from the working surface to the lighting installation point can be ranging from 10 feet to 60 feet. Flood light is widely used in large area, probably for outdoor opening place, to check the whole site or one big site for overall looking, the lighting beam angle can be adjustable to direct the approximate visual position.
