I have been using PRS 6 months

most
-> Low consumption 30Watt
-> The light output for the price (compared to the other leds 1-3W)
-> These machines are comparable By Power 500W depending on the color
-> Fast strobe trs.
-> Rglage of 5 CHANNELS: Dimmer, Strobe, Red, Green, Blue

the least
-> Weakling in the red
-> Use only for the color
-> Rglage the strobe: trs slow to beginners and a good length of the beach rglage.

The report price is plutt good quality:
6 Par 64 lamp dimmer + ~ 500euros
Led 6by: ~ 600euros

So for a small power loss and over 100euro. You have a choice of colors trs important (on deck without changing the gelat!) Even if I am not sr we come to do all variations of glatines ...
