Introduction: Reuse LED Strips in Fluorescent Fixture
About 10 years ago, I put some fluorescent fixtures in my garage so I could have ample lighting for making and fixing stuff. Well, at least twice, I've had to replace the fixtures because the bulbs wouldn't light. Yes, I made sure the bulbs were good in other fixtures, but no light. And there was no user changeable ballast or starter. So I was stuck. Buy new fixtures.
This last winter, I had two of the four fixtures go bad, and I was really dreading spending $20 or more on each new fixture, so I put it off.
A few weeks ago, I went to visit my parents, and my dad had a box full of some old under-the-cabinet LED strips. I thought to myself, this is the answer. Remove the fluorescent tubes and electrical components, attach the LED strips, use some old 12V DC converters, and boom. Free lights that would last for years and years with minimal energy use.
So, I packed up the LED strips and flew home. My plan to spend $0 almost worked. I wound up having to buy two LED driver power supplies from Amazon as the standard 12V converters I had induced some flicker in the LEDs.
This is what you need:
(1) Fluorescent tube fixtures ( mine were two tube ,48 inch models)
(2) Some 12V LED strips, buy your own, or scavenge like me.
(3) Self-tapping sheet metal screws
(5) Basic soldering skills or LED strip connectors (I got skillz)
(6) 5.5mm x 2.1mm panel mount DC socket (or a screw terminal socket)
Read on to see how its done.
Step 1: Take Apart the Old Fixture
Unplug and remove the old fixture.
Take out the old light bulbs. Be careful, they break easy and are a pain to clean.
Once you have it on your work table, remove the plastic end caps so you can remove all of the electrical components. My cheaply constructed fixtures had no screws or bolts, so I was able to pry off the end caps with a flat screwdriver. I had to cut the wires to fully remove both ends, but cut them close to one end so I could save them for future use.
Step 2: Attach the Clips
My LED strips came with some spring clips.
Attach them to the fixture with some self-tapping sheet metal screws.
Step 3: Connect the LED Strips and Plug
This is the time where your soldering skills come into play.
Or if you are not confident in your soldering, you can get some 2 pin LED connectors from Amazon.
To keep things easy, and standard, use red and black wire. Solder black wires to '-' and red wires to '+'.
To get power into the strip, I used a 2.1mm x 5.5mm Panel Mount DC socket. Again, if you are not big on soldering, you can get one of these DC connector sockets that have screw mounted terminals. The LED power supplies I bought came with the screw terminal sockets.
Step 4: Test!
Once everything is connected, plug in our LED power supply, and then plug it into the socket in your fixture.
If you've done everything correctly, then you should be bathed in beautiful LED light.
Lastly, hang your fixture, plug it in and you'll be good to go. In my garage, the power outlets in the ceiling are controlled by the wall switch, so I don't need a switch on my fixture. Depending on your setup, you might need to add a switch to the circuit or just plug and unplug as needed.
