This place
http://www.celestialaudio.com/dmx_led/
makes DMX dimmer packs for LEDs. Not a bad price either.

32 channel DMX 4-Amp LED dimmer pack:
this board controls 32 LED
clusters (or anything DC powered) of up to
48V -AT- 4 Amps each.  Beefy! 
$259 USD.



48 channel DMX 20mA LED dimmer pack:
this
board controls 48 LEDs (single
LEDs or several in series) at 20mA each,
with no current-limiting resistor needed.  $159 USD.
