Color and Consistency Issues With Led Light Strips

There are internal connection issues within my led lights strips. Theyíve been properly set up, cut, and connected. On one light strip, the tail end is a different color than the rest of the strip. For example, if the color i want to use for my lights is green the single problem section will be purple. On another light strip thatís connected through a power connector the light will only connect to one wire port even though theyíre all touching the metal wires. Iíve switched and flipped and fumbled with these strips for weeks and have yet to find a consistent solution.

The color of a single LED is the result of the semiconductor compound used in making the LED. It can't be changed. I assume the strips you have are a mix of colors. There are many variables that can affect the color of each strip like different manufacturers, different batches of semiconductor compound, poor quality control, etc.. I see no way the consumer has any chance of controlling the variables.

Welcome to the forums.

Can you leave us a link or tell us what strips you're using ?

If that one section is always a problem... replace it. It may have a defect. As for the connections the only thing reliable that I have found is to solder the wires to the light strip. The clip on connectors very often cause troubles.

Thanks for the replies. The lights I used were two varying lengths of Lepro strips. The issues first started when I tried adding strips down the corners of my room to the already assembled and set up lights around the rim of my ceiling. Iíve flipped the lights, attempted to force connections, cut and re-cut, replace the sections that were poorly cut and it is the same issue. If itís a manufacturing issue would there be anyway to file for a replacement or refund since Iíve done so much work on them. Iím not sure if itís something iíve done in the process of setting them up or if it was doomed from the start. Both light strips were bought at separate but close times. Iíll gladly send pictures of the issues if anyone needs visual reference. https://www.amazon.com/Lepro-Ultra-L.../dp/B086V83WGS

Not all LED tapes are designed for cutting and splicing.
I don't see any mention of cutting them in the product description.
Is the problem you are having splicing them together ?

Iím not sure if the product listing states that they can be cut but every box I received came with a pamphlet explicitly saying this alongside visual instruction on how to do so. The instructions were a bit vague but they were there. Plus the strips all have cut marks with scissor going on them, which I would assume itís encouraging splicing. But I can and have cut them and even fixed the ones I slightly messed up on, theyíre set up correctly they just wonít light up properly and Iím not sure why.

Any time I've done long runs of LED tape lights I buy a roll to do the entire job plus have some leftover for spare parts. I don't trust buying two different packages that could have been manufactured at different times and might have different led emitters.

Are your color variation problems limited to sections you've cut and spliced together? It's not as big an issue with white strips but with variable color strips the color you see is dependent on the voltage. A poor connections along the way that can affect the color. I've found soldering to be the most reliable. The clip on connectors have been very problematic from every manufacturer I've tried.

I've also done long runs. There can be a noticeable difference in brightness between the end where power is fed and the far end. Usually it's not noticeable if the far end is somewhere else but if you are forming a loop like around the perimeter of a room, putting the feed end and far end next to each other can make the brightness difference noticeable.

No..... the cut marks encourage cutting them to length at the marks but not splicing.

Just figured out what splicing is. I didnít do any of that, just standard cut and reconnect via connector. Iíll look into soldering. Where would someone very inexperienced start? If I solder them would that kill any chances for contacting the original listers for compensation?

this is basically the setup but on every wall in my room. would it be best to just take the sides down to lessen droops and hangs in the strips? they were working perfectly before the extra sides were added.
