Electrician help! Dimmer Switch says 'do not use with less than 60 watts'. Why?

I'm looking to run some screen lighting for my projector - but its only 30 watts total (among 5 lights tranformers, tolerant of funky AC)... Will the triac inside not fire properly without load?

. Some circuits require a certain amount of load to be stable. . My guess is that at low loads the triac will spend too much time not fully on or off and will overheat.

Not sure if this helps but when I tried using a dimmer with a low wattage CFL bulb in my loft it made an audible buzzing sound appear at the consumer unit.

Thats what I figured... Thanks.
. That is just a guess. ;)
