In the new test standard of UL about LED drivers, there are class 2, class p, type HL standard, Then what is type HL?
The type HL standard of driver is defined in UL8750. in a word, it can be installed in Class 2 Division II lamps for hazardous locations (Hazardous Location).
Any LED drivers marked with “Type HL” can be used directly for terminal lamps installed in hazardous (classified) location areas without further evaluation. For example, if you are using our waterproof led driver 12v 10a 120w to the projects where located in hazardous locations, just make the connection directly.
If you are using other kinds of our dimming driver, slimline led driver, junction box driver, that is also could be installed directly, as they are are with type HL standard.
