Introduction: LED Flood Light With Motion Detector

About: Hi y'all. I'm Leviathan17. For more info on Leviathan ,look up Job 41:18-21. I am a Christian, but don't be scared cause I do have a lot of good ideas. I love listening to the wisdom of the older generations. …

Make a LED Flood Light With a motion detector for only $15!

Thanks for checking this out. I think this is my 26th instructable so thanks to all who viewed and commented on my previous ones.
Cost Estimates:
LEDs--- $10.00 two strips(preferably waterproof)
Motion Sensor--- $5.00

Competence level: Intermediate

I needed a flood light for the back door of our barn and thought why not make it out of LEDs. I thought they would be super bright so why not?
The dimensions are rough estimates of what I can remember. Its size is up to you and depends on the materials you have. Anyhow I hope this helps you out.

Step 1: Tools and Materials

needle-nose pliers
Swiss Army Knife is very handy for this
Wire cutters
mieter saw

soldering iron
two rolls of LED strips
AC to DC power converter
motion sensor
aluminum foil
heat shrink

Step 2: Reflector Backing

I wanted to be able to reflect as much light as possible,so I used aluminum foil with double sided tape on the back.

Step 3: Apply LEDs

Next take and apply your LEDs to your back board. I used two whole rolls. The boards dimensions are 12x16 inches. But the size is up to you. This is just to show you how it all fits together. Make sure you leave room for soldering them together.

Step 4: Soldering

I soldered them together in parallel. It may not look super neat but it is very dependable and study. Test your lights frequently so you can find any problems before you get to far away.

Step 5: Cut Your Glass

I used glass from an old window for the front. Plexiglass would be easier, but that would drive the cost up. My grandfather helped me cut this so I'm no expert on glass cutting. If your not sure how to cut glass there are other good instructables on cutting glass.
But here are a few pointers: make sure you score it right the first time, cause you cant do it again. Put an rug or towel under it so when your tool comes of the end it wont hit the table and damage the end. Also use gloves and safety glasses.

TIPS: Glass is very easy to get now a days. One of the best places to get glass is goodwill.
Just find a picture frame and take the glass out of it. Then make you light the size you want.

Step 6: Construction

Sorry I don't have better pictures of its construction. The pictures I had got erased accidentally.
Basically there are four sides each about 3 inches wide. The glass rests on two strips of wood on the top and bottom. I used window screen clips to hold the glass on the front. DON'T over tighten them or you will crack the glass.

Step 7: Box Assembly

I assembled somewhat of a angled box on the back to hold the wires and for mounting. The wires for the LEDs comes out of the top and bottom of the back board. After I put those together securely I put heat shrink over them for a clean and nice fit. I put a board on the back for mounting. I drilled a hole though it and tied the wires in a knot in the back so they couldn't get yanked out.

Step 8: Final Assembly

I mounted above the door with two screws. I drilled a hole through the wall and ran the wires inside to the power converter.

Step 9: Other Sensor Applications

Also you could put one of these on it so whenever you open the door it turns on. It stays on for 30 minutes then shuts off.

Step 10: Done

The turnout was very good! It was brighter than I expected. The sensor needs adjusted ,which is easy.

I hope this helps you out. If you have any questions, comments, ideas, suggestions, or complaints let me know.
