I'd like to link two 20' LED light strips together. Each strip comes with a 12v, 2A Power adapter. The adapters that came with these sets make a humming noise, so I want to replace them. Rather than have to buy two new power adapters, I'm wondering if I can just buy one same (but quieter) adapter for both sets. If that would not be powerful enough, could I buy one 12v, 4A adapter or maybe even a 5A for more power?
I have 8 LED sets in total for my project and I want to link 2 together for 4 different places so that would be a total of 8 new power adapters or just 4 if what I'm asking above will work. Please let me know. Thanks!
