Rextin Super Bright 200pcs 2835 LED Module - 120-150LM per Module, Waterproof Decorative Lighting for Letter Signs & Advertising Displays with Adhesive Backing, 3-Year Warranty (Blue) - Perfect for Storefronts, Wedding Decor, and Event Signage

I changed out fluorescent bulbs to these LEDs in my 10’ x 3’ sign. I used a 200 w 12v power source hardwired to power. I used 6 strands each containing 20 led modules for a total of 120 led modules for this project. From my calculations, each strand requires 24 watts. So that means 6 strands would require about 150 Watts. That is the reason for a 200 W power supply. You are supposed to only use 80 to 85% of the total power supply. Each strand was wired back to the power supply outputs so there would be no voltage drop. I did use flat white spray paint to clean up the back of the sign cabinet. I also used a small amount of silicone on each module so they would not come off if the 3M adhesive dries or fails. So far, it is working like a champ and the lighting of the sign is consistent. I am very happy with the result. Hopefully, these will last a long time and I won’t have to replace bulbs or power supply for many years.Update: I did both sides of my larger 14’ x 4’ main sign with these as well. Let me tell you, I am estatic with the results. I placed the strands 6” apart in rows and it turned out fantastic. Hope the pictures do it justice. I used 2 - 200w power sources on each side to power the leds. Saved a bundle over having a sign company do this.I thought it would be a bit brighter. Not that greatVery Cool Bright LightsI installed 1 signage a year ago and still didn’t get any complain still same bright qualityHope it will last more ?PrintmateUsed 4 strands to retrofit a box sign. The tape does not hold but most never does. Cant know if they last until time has gone by but initial rating is good. Time will only tell.These led modules are working perfect for my home Bru kitchen cabnet lighting. Easy to hide. Easy to configure to any lighting project. Inexpensive and more than enough to light every cabnet I have including a accent light project. They have been in service for several months now with zero issues. And professional results. I used 4 to 8 modules hidden on the back side of the face frame, used 16 gauge wire, small paddle switches and hot glue to secure wire and lights. The double sided tape on the lights holds well on a smooth surface but on the Simi ruff surfaces they would come loose . Simply added a spot of hot glue to each end after they were stuck in place. I'm buying again for a master bathroom.Ordered these light to make bait lights for fishing. They arrived quickly and seem to be pretty bright. They come 20 lights to a strand and 10 strands. Which worked out well for my needs. Would like them to be brighter but they were good price and work well and water proof but not submersible.Replaced old fluorescent HO lighting in a double sided pylon sign. I took 3/4" aluminum extrusion and adhered the LEDs on both sides. Original lighting was three bulbs on each side of the pylon, I replaced with five of these led sticks, then used HLG power supplies. I figure it is using 1/3 of the wattage of the florescent bulbs and is almost as bright as new bulbs.I was nervous about this project and how it would turn out.Boy am I impressed with the outcome! The sign is updates to LED andLooks amazing now.My sign is approximately 3’ tall by 12’ wide and maybe 6” deep. I used the entire pack in this sign and it was the perfect amount.The tape is good quality so that makes the install reasonably quick.Been going dawn to dusk for a couple of months now with no problems.
