Introduction: Floating Shelf W/ Hidden LED Lighting
This floating shelf features a hidden LED lighting panel on the underside, so it's perfect to place over the bed, or anywhere where you'd like some direct downward lighting. I used a piece of live edge maple, however you could use any piece of wood you have on hand, a 2x4 would be great!
Step 1: Hardware
I'm using some floating shelf hardware, and this is really easy to put together. You just attach the brackets onto studs on the wall, assemble the pieces, and drill holes in your shelf so it slips on the hardware.
Step 2: Preparing the Wall
The first step is to prepare the wall by finding where the studs are, then drawing a level line in between, and marking where you need to attach the brackets. Then pre-drill, and attach the brackets with screws - I used 2 inch screws and it's a good idea to use rather long ones for extra support. Once the brackets are in place, and the bolts are screwed in, I marked where on the wood the holes needed to be drilled.
Step 3: Drilling the Holes
Once you've prepared the wood by cutting it to a size that fits your space and making sure it's nice and level, it's time to drill the holes to attach it to the hardware on the wall.
I made up a little jig, by drilling through a block of wood on the drill press. I used that guide to drill through the wood, thereby making sure it was perfectly straight. It's important the holes are drilled straight, because the shelf won't go on the hardware right, and for this I used this extra long 7/16" drillbit to reach.
Step 4: Recessed Area
Now to create the recessed area underneath, I'm routing out two different depths, the first one more shallow, and this is where the acrylic will sit, and deeper depth for the lights. I made a little router jig with an adjustable fence to make sure that I stayed within the space I wanted for the routing.
Once the routing was done, I sanded the wood on all sides.
Step 5: Acrylic Insert
For the frosted "glass" insert I'm using a piece of acrylic, this is 1/8 of an inch, or 3mm thick. This cuts pretty well on the table saw. The section I had routed out within the wood was just a touch longer than the acrylic piece, so I had to cut up an extra piece and then cut to fit.
When using a router, you get round corners, so in order to fit the acrylic I'm cleaning up the edges with a chisel.
To create a cloudy effect on the acrylic I spray painted both sides with some frosted glass spray paint.
Step 6: LED Lights
I began with cutting up four strips of LED lights to fit within my recessed area.
Step 7: Hide Wires
To be able to hide the wires behind the shelf I'm first drilling a hole, and then routing a section for the wires to fit in. This is a little jig for the router with a fence attached, and it's so we can route a straight line on the edge of the wood which the cord can fit into, and it's a small bit.
Step 8: Type of LED Lights Used
I decided to go with high quality 90 + CRI LED lights that are daylight balanced. The setup here consumes about 36 watts at full brightness, which is very bright, most of the time I'll probably keep them dimmed. So I added a larger 60 watt AC DC adapter to handle that.
Step 9: Soldering
So I'm just connecting the positives on one line, and the negatives on another. And of course testing with the multi meter to make sure I have no shorts anywhere.
At the end of one of the strips, I soldered on wires which are pulled through the hole drilled and then hidden within the section routed.
Step 10: Attaching the Acrylic
To secure the acrylic I'm using a very small amount of hot glue in a couple of places.
Step 11: Finishing
For a finish I'm using water based poly, because it dries quickly, and I like how it doesn't add a yellow tone.
Step 12: Twisting the Cord
We used a drill to twist the cord and then soldered on the connection for the plug to the lights.
Step 13: Wax Polish
Finally, I'm just finishing the wood with a coat of my tung oil and beeswax polish with some steel wool, and then buffering to get a super smooth finish.
Step 14: Installing
To install on the wall, I simply slid the shelf on to the brackets within the holes drilled in the back of the wood. I then used a plastic self adhesive channel to hide the wires. I plugged it in, and it's all done!
