Lumen Bright SE Pendant Assembly Instructions Step 1. Attach Slide bracket with the four screws provided to the side of the pendant where the large hole is located. Step 2. Screw bulb into mogul socket assembly. Step 3. Slide bulb attached to mogul socket assembly through the large hole and align the bulbs inner arc tube in the center of the reflector. There is a small hole at the top of the reflector that marks the center. Step 4. Attach wing nuts that are provided to fasten down the slide bracket. Apply a little pressure to the flat metal surface where the wing nut screws are located. Because of the extreme angle of the Lumen Bright reflector there will be a little resistance. Screw the wing nuts in place and you are ready to wire the cable to your ballast. Step 5. The Lumen Bright pendant comes with eye hooks that thread to the top of the pendant for hanging. Note: The best light output of the Lumen Bright mini is achieved with a hanging height of 14” off the surface of the water from the very bottom of the pendant. At this height you achieve the most efficient metal halide lighting of any reflector on the market. You will also reduce the amount of heat that is place back into your aquarium.
