GR or -CSA version, item 11) to the appropriate source. (NOTE:

white wire (9) is connected to the lamp socked shell (8)).

(C) For P/N 40940, position the fixture on the mounting column (20)

(See figure 1) and loosen the three binding screws (6) half a turn. Thread only the globe support hub (12) (to avoid twisting wires) to full thread depth and secure the locknut (13). With the globe support (1) fully bottomed on the hub (12), tighten all three binding screws (6).

(D) For P/N 50033, insert 90° elbow (14) into globe support (1) (see figure 2). With the globe support (1) fully bottomed on the elbow

(14), tighten all three binding screws (6).

MKR-LTG1-0IR

L-810(L) LED Obstruction Light with Infrared (IR)

The MKR-LTG1-0IR Single Obstruction Light integrates visible Red LEDs and Infrared LEDs into a single L-810(L).

Infrared energy (IR) can enhance compatibility with Night Aviator’s Vision Imaging Systems (ANVIS) and Night Vision Goggles (NVG). Precision molded Fresnel Optics produce a low ground scatter tower lighting solution. The die cast aluminum base provides 3/4 inch conduit hubs for side or bottom mounting. Multiple 9kA MOVs and a 20kA gas plasma discharge tube provide robust surge suppression.

Night Vision Goggles (NVG) and Aviator's Night Vision Imaging Systems (ANVIS) translate infrared energy (IR) into brightness variations on a human visible display. These systems utilize various filters and technology that affect their sensitivity to infrared energy (IR) of different wavelengths. International Tower Lighting, LLC (ITL) makes no claim or representation that the infrared energy (IR) emitted by ITL obstruction lights is visible to any NVG, ANVIS or other night vision imaging system. In no event shall International Tower Lighting, LLC (ITL) or any of its representatives be liable for any damages, including, without limitation, direct, consequential, indirect, punitive, incidental or special damages, in connection with the infrared energy (IR) emitted by ITL obstruction lights and/or whether any NVG or ANVIS can detect such Infrared energy (IR) or whether the infrared energy (IR) emitted by ITL obstruction lights is visible to any NVG, ANVIS or other night vision imaging system, regardless of the form of action.

Features Integrated Infrared Emitters can enhance compatibility with Aviator’s

Night Vision Imaging Systems (ANVIS) and Night Vision Goggles (NVG).

Rugged die cast aluminum base.

Stainless steel latches and hardware.

3/4 Inch conduit entrance, side and bottom hubs.
