They are unregulated supplies. Voltage varies with the current drawn. 24v is outlet voltage when the current drawn is at the rated 2.5, or 5Amps.
No load voltage is approx. 34volts (ac) and this drops towards the 24v when the load is increased. If you've got the lights on a sequence, then they will only draw the current for the lights that are on at any one time. e.g 100 LEDs on will only draw approximately 250mA from the transformer and the supply voltage will rise momentarily until other circuits are on (hope that makes sense!!?)
I use a mixture of regulated and unregulated supplies when I put up my displays, depending on how I've mixed the light strings, and what sort of sequence I'm running. I've got a video of this year's display, but no music and most of the video is concentrated on digital projection (to show relatives in Scotland), I've used regulated and unregulated supplies. If you want to see it, I'll post it and try giving you some pointers as to what I've used
