Question: Can these be connected together to make a longer strip?
Answer: Sorry but cause the voltage and power reason, the lights don’t support you add another light strip to make a longer strip light.
Question: Can this product be cut in multiple pieces and resolder the joints to make it all work or is it once i cut it the rest is garbage?
Answer: Do not suggest to cut and re-connect. The strip can be cut only at copper joints which can't be resoldered. The cut part is not reusable. After being cut, the end should be sealed with glue first and then covered by an end cap.
We provide a complete set of accessories for installation, such as buckles, cable ties, glue, etc.
Note: Glue should be used to repair after cutting, otherwise it will damage the waterproof property.
Don't cut it unless you have to.
For the stability of the led strip lights, please fasten the strip lights with Mounting Bracket (package include) after stick the strips to the wall.
Please take the light from the reel before testing the product.
