I know that a spot can do more effects with gobos and prisms but considering that wash fixture are generally brighter and they do CMY mixing it makes it difficult to choose. I really like the look of the above youtube video as the lights change color down the line. I am guessing I am looking at Mac 300's by what is listed in the youtube video. Are there any tricks other than the rainbow effect that I am not seeing with the washes? Some friends have recommended that I don't get washes because they say you can get close with prism, iris, focus and frost control. I'm just wondering that if you applied all those effects would it be less bright than a wash in the first place. Looking for advice, pics, videos and anything that will help me with my future purchase. Thanks!
