  • Flexible Solutions: We have the right combination of equipment to suit your requirements, regardless of your PD test application.
  • Field Experience: We have been designed, manufacturing and installed many PDTS over the years.
  • Single Source Supplier: All the components are designed, manufactured and tested by a single supplier, guaranteeing their ability to function together.

The VM2L/VM4L Series is a low bay and high bay fixture using energy efficient LED's. The design of the VM2LB & VM4LB with the bulb style heat sink creates a light distribution similar to a HID lamp. The design of the VM2LC & VM4LC with the concave style heat sink creates a light distribution with no up light. This fixture is made with a cast copper-free aluminum housing and mount that is suitable for harsh and hazardous environments. With the design of this fixtures internal heat sink keeps a clean look on the outside of the fixture creating a LED fixture that does not contain external heat fins.
