Before saying it does not work, please tell us what you have done to rule things out and provide a bit more details.
Have you used the Postman utility from a desktop to make the requests as you are doing here?
Does your label have a url like this, for example: http[colon][slash][slash]myhost.net//api/Y1Vpd5qwJVnjsRIdxFThJR0jsdcdaEvrQVe0NYM/lights
or one that is simply the host name, for example: myhost.net
Please also note that an http request's response comes with multiple lines with CRLF (\r\n) separators , not just the json markup. Your use of 'split' worries me and is very 'fragile' to say the least.
Have you debugged using try/catch to confirm the socekt is working? Also I don't see a socket.close call except in the 'catch' block. There also needs to be one after reading all data, otherwise you will run out of sockets. Again, have you debugged and review the Diagnostics log for errors such as out of sockets?
Have you done System.print on the variable named 'info' as things come back?
