Not directly, no. You need a zigbee gateway (Hue Bridge, Tradfri gateway etc). According to this Hue bulbs can be added to Tradfri gateway (

Think of the zigbee gateway as doing the same thing as your wireless router. You can't cast stuff from your phone to your TV, or from your PC to your ipad without the wireless router - the zigbee gateway does the same thing.
Edit: Just seen you were looking at Innr bulbs instead, according to this they should still work with Tradfri gateway:

I don't know if the Tradfri gateway can be had any cheaper mind. Looks about the same price as a second-hand Hue bridge off ebay.
