Sure you can. 3 way 'mechanical dimmer, ie LUTRON Skylark' at one location,and a 3 way switch at second. 3 conductors between them just like with the switch. OR...a 3 way 'electronic dimmer ie LUTRON MAESTRO' at one location and its ' Accessory Dimmer' at the other. Same wiring as above. With this setup, the lights can be turned on/off AND dimmed from both locations.
Because they are LED lights, you should make sure you get the 'C.L' version (specifically designed for LED and CFL dimmable bulbs) for the best dimming performance.
Home Depot will have all these devices in stock...
