3528 SMD 6000K Cool White LED Strip Lights - 12V DC, 1200 LEDs, 16.4Ft Flexible Tape Light for Bedroom, Kitchen, Cabinet, Home Decoration - Non-Waterproof Ribbon Lamp (Ideal for Accent Lighting, Under Cabinet Illumination & DIY Projects)

Here was my dilemma - I had a 2' x 2' light fixture installed in a pantry / laundry room that 'used' to provide bright light in the room. After 20 years, the double ring fluorescent light was flickering and the room looked like something out of Stranger Things. I wanted to install a new bright LED light fixture. After shopping at the big chain lumber yards, I decided I didn't want to spend $70 - 100 on a new light fixture. My wife liked the look of the old fixture and we just needed a replacement light solution. The fluorescent ring bulbs are both expensive at this size and terribly inefficient. Instead, I ordered this double LED light strip along with the "COOLWEST Transformer Driver Power Supply 60W 12V for LED Strip Lights". When everything arrived, I pulled down the white diffusion lamp cover (very important to re-use here) - cut out the original ballast and removed the 2 original circle fluorescent lamps. I then wired up the LED power supply (mentioned above) to the original 120V feed that went to the old ballast. I screwed in the wires from this LED strip and tested my connections briefly (on for a couple seconds - no more to reduce LED heat while in the spool). Super bright - perfect! Now I removed the backing and slowly "taped" a spiral making 90 degree turns by folding the LED light strip neatly around corners - without binding the surface mount components. My corners stick up some but no problem hitting the original cover that I would install later. I continued this, spacing my LED's lines about 1.5" apart from each other as I went around the surface of the original white metal light fixture. I had plenty of LED's to do the job, cutting off about 2 feet that I didn't need. I powered up the LEDs and they were super-bright and very white. Perfect! I re-installed the white diffusing cover from the original fixture and the light was no longer piercing, but perfectly diffused. My wife loved the brightness (with cover on) and I saved a ton of cash by keeping my old fixture and using this LED strip and a 12V LED power supply. I highly recommend this as the cheapest option if you are looking to replace bad fluorescent lamps but still love the look of your fixture. While I'm an electronics / electrical tech with 20+ years and had no problems at all doing this in 10 minute - you can easily do the same job as long as you read all instructions, take your time, use the proper tools, disconnect power (flip the breaker) while working, etc - probably within 1 hour or less.
