This is a controller to turn on and off TP-Link Smart Bulbs, specifically the LB-120. It's based on Lubomir Stroetmann's work here.

I won't get elaborate with the usage. It's the same as the tplink-smartplug.py program. Invoke like this:
./tplink-smartbulb.py -t <ip> [-c <cmd> || -j <json>]
The available commands are on, off and info. Anything else you'll have to send as JSON. If you want more in depth commands just go visit Lubomir's github, seriously. It's a good resource.
