Pre-Installation

Location Selection
Choosing the proper locati0n for your wall mounted light box is critical. The locati0n you select enables good operation of the light and makes it easily accessible. Think about these things:
Visibility: Position the light box where it illuminates what you want. Adjust the height and angle for best light.
Accessibility: Position the box 6 to 8 feet high. So, you can clean or replace bulbs with ease.
Environmental Conditions:Examine the environment for wind, rain or other adverse conditions. Choose a locati0n that will protect the fixture and wires.
Fixture Compatibility: Some light boxes may require extra space or specific angles. Check to make sure it fits, in accordance with the manufacturer’s directions.
Surrounding Landscape: Look for whether other trees, buildings or things block out the light or make shadows.
Tip: Use a tape measure and level to measure the distances at each place you mark. It helps you keep your light BOX straight and at the right height.
Wall Structure
Check the wall before you drill holes. Drywall, brick, and concrete need different anchors and tools. Use a stud finder to find studs in drywall. Putting the light box on a stud gives it more support and stops it from sagging. For brick or concrete walls, use strong anchors made for masonry.
Mark where you want to put the light box with a pencil. Check your measurements again so you do not make mistakes. If you see pipes or wires behind the wall, pick another spot to avoid breaking them.
Safety Checks
Anything electrical, the number one thing is safety. Before you begin, do these things:
You can search for your state and local codes. Ensure your work complies with the National Electrical Code and local regulations.
Switch off the electricity at the circuit breaker or remove the fuse. Use a working voltage tester to ensure the wires aren’t hot.
Take insulated-handled tools for circuits containing energized components. This makes you safe from electric shocks.
Note: Be sure to test the power before beginning. Skip this step and you might hurt yourself or something.
Wall Mounted Light Box Installation
Image Source: pexelsPutting up a wall mounted light box takes planning and care. You need to follow each step so your light box holds your graphics well and works safely. This guide shows how to mark spots, drill and anchor, put up the bracket, do the wiring, secure the light box, and connect the adapter. You will also get tips for both regular and LED seg light box installation.
Marking Points
Marking the right spot is key for a good wall mounted light box installation. You must draw where your light box and graphics will go. This helps you line things up and gives support.
Put a level on the floor and hold it straight by the electrical box.
Use a pencil to mark the top and bottom of the box on the level.
Draw a line along the side of the level onto the floor.
Do the same on the other side of the electrical box.
Put the drywall sheet on the wall. Stand the level on one of the pencil lines on the floor. Hold the level straight and draw a line up on the drywall. This marks one side of the electrical box.
Move the pencil marks from the level onto the drywall for the top and bottom of the box.
Stand the level on the second pencil mark on the floor. Hold it straight and draw the last line up.
Connect the lines to finish the outline of the electrical box.
Cut along the lines with a jab saw to make the hole.
Tip: To mark faster, use a mark-and-cut transfer sheet. Peel off the back, stick it to the electrical box, put the drywall in place, and tap with a rubber mallet. The shape moves to the back of the drywall, so you can cut it out easily.
Drilling & Anchoring
The locations to support your wall mounted light box and graphics must be drilled and anchored. Use a stud finder to locate your wall studs for optimal support.
Have your drill, screwdriver, anchors and screws ready.
Shut off the power at the circuit breaker before you begin.
Sketch your plan and confirm where the light box will be.
Pierce the plastic with small holes at those points. If you hit a stud in the wall, use wood screws. For drywall or brick, select anchors that can support the weight of your light box and graphics.
Put anchors in the holes. Pound them in lightly with a hammer if necessary.
Note: Larger light boxes and graphic displays will require wider brackets and stronger anchors. Always verify the weight limit first.
Mounting Bracket
The mounting bracket keeps your wall mounted light box and graphics safe. You must line it up and attach it carefully.
Line up the bracket with your marks. Use a level to keep it straight.
Attach the bracket with screws or anchors. Make them tight, but do not make them too tight or you could hurt the wall.
Make sure the bracket can hold the weight of the fixture. For bigger seg light box jobs, use a wider bracket for more support.
Alert: If you cannot find a stud, use strong wall anchors made for your wall type.
Lightbox Wiring
Good wiring makes sure your wall mounted light box and graphics light up safely. Always follow your local electrical codes.
Connect the wires from the wall to the light box. Match black to black (hot), white to white (neutral), and green or bare to ground.
Use wire nuts to keep the wires together. Twist the wires and cap them tight.
Tuck the wires into the junction box. Do not pinch or bend them too much.
For LED seg light box installation, connect the low-voltage wires as the maker says. Check the plus and minus for LED modules.
Tip: Use a voltage tester before touching wires. Make sure the power is off so you do not get shocked.
Securing the Light Box
You must attach the light box to the bracket and wall so it stays up for a long time. This keeps your graphics safe and the light box working right.
Put sealant on the back edge of the fixture base.
Attach the fixture to the anchors and line it up right.
Tighten the screws, but do not make them too tight. Too much force can crack the wall.
Add more sealant around the edge of the fixture.
Smooth the sealant for a neat look and strong hold.
Check that the sealant covers everything with no gaps.
Turn the power back on and test the light box.
Press on the light box gently to check if it is steady.
Plan to check the sealant and hardware from time to time.
Note: A tight mount stops sagging and keeps your graphics safe from harm.
Adapter Connection
Adapters link your wall mounted light box to the power and mounting hardware. Most adapters screw onto a center stud, with a nipple for the fixture.
Attach the strap to the fixture outlet box.
Fix the wall fixture with screws, following the maker’s steps.
For LED seg light box installation, use the adapter given and connect the low-voltage wires as told.
Make sure all connections are tight before turning the power back on.
Tip: Always look at the installation manual for your light box and graphics system. Some makers use special adapters or ways to mount.
When you finish these steps, your wall mounted light box will show your graphics well and work great. Now you can put in the graphic and enjoy bright displays in your space.
Troubleshooting
