Hello,
the Belkin Wemo lights are interesting. They appear to have Zigbee but after a quick Google search it seems that they cannot be paired to a hue bridge. Note that I have not tried this myself as I do not have Belkin Wemo lights.
If these lights cannot be paired with a hue bridge, there is not much I can do for you. It could be that Wemo bulbs are compatible with deCONZ, but that is also something I cannot confirm myself.
Support for Samsung SmartThings is on the wish list for future development: Smartthings Integration
