Thank you for your comment @caranax! After you open the Lightning Network channel then Lightning Network payments are instant and very very inexpensive. To open the LN channel you have to send required amount of Bitcoin to your LN node. This cost and take time like a normal Bitcoin transaction. When you decide to close the LN channel, the Bitcoin balance on your LN node will be transferred back to your wallet. I think if you will follow the steps you should be able to make a LN payment but of course the Bitcoin and Lightning Network are very complex technologies. Good luck!
