Looking to replace ac/dc adapter from our samsung woofer for tv sound bar. anyone else use for tv sound? will it work for that application? thank

You can confirm your samsung woofer working voltage , if it is DC12V , it can work .

I am using this on under-the-counter led lights. will there be a delay turning on or will they be instant on?

If you connect to the LED light , they will be instant on . Delay turning should need a controller to make it . Do your under-the-counter led light have a controller for it ?

how many 12v LED Strip lights can you connect to one power supply?

It is hard to know . Because you have to know the watt for the LED strip first . This power supply is DC12V10A 120W . If you led strip is DC12V 50W,well you can power two LED strips . If you led strip is 100W , you only can power one LED strip . The watt of LED strip is important . Any another product question , please feel free to contact us support@btf-lighting.com Best regards BTF-LIGHTING
