I was pretty ignorant about LED lighting when I bought this and didn't know the difference between waterproof and non-waterproof strip. I managed to buy waterproof by mistake. This connector is for non-waterproof strip (the normal stuff) but works on the waterproof variety fine - you just have carefully to remove a little of the plastic coating from the end of the strip to reveal the electrical contacts.
Be aware that there is a connector on only one end of this adapter - the other end is bare wire (pre-tinned with solder) for connecting to whatever you want. If your LED strips are some distance apart (like on different shelves) then this is what you want so you can connect some joining wire.
