The VM4L Series is a low bay and high bay fixture using energy efficient LED's. The design of the VM4LB with the bulb style heat sink creates a light distribution similar to a HID lamp. The design of the 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.
Supplemental 20KA/10KV Surge Protection is standard for 120-277 VAC models & 10KA/10KV Surge Protection is standard for 347-480 VAC models.
