A bit more reading suggests it is a digital (new models) v analogue. I'm no expert. The digi models are more expensive of course.
I'm no radio engineer, so the electronics guys may know better, but in my particular interest in electronics, high tension audio amps and electrostatic and horn speakers
http://www.audio-talk.co.uk/fiultra/JUTE%20ON%20AMPS.htm, digital gear is as susceptible to interference as analogue, and often a good deal more difficult to shield against it. Something to consider and ask about before you lash out cash.
Something else that you may not have considered: a few milllimetres this way or that between the wire for the lamp and the wireless computer gubbins may solve your problem.
