UL announced the launch of "Type HL" LED driver certification for hazardous locations on July 26, 2013. The hl led driver refers to the relevant requirements of ballasts, and is added to the standard "UL8750 LED devices used in lighting products" as a certification requirement resolution (CRD). The appendix SB of UL8750 lists specific requirements for "Type HL" strip led driver. The key points are as follows:

"Type HL" type LED driver should meet UL8750 related performance requirements

"Type HL" type LED driver should meet UL8750 related structural requirements

Except for the input and output leads, all components inside the "Type HL" driver should be completely submerged in the potting compound

The LED driver that meets the requirements can obtain the mark "Type HL" for hazardous while obtaining UL certification. Depending on the product category or classification occasion, the "Type HL" driver will be awarded the Listed or Recognized qualification.

After selecting the ac dc led driver with the "Type HL" logo, the lighting products will be exempted from some special tests required for the use of the LED driver in the lamps of hazardous locations,
