I always forget the Nexras. They definitely do deserve consideration along with the Scrollers and Seachangers.
What sort of light board do you have? Unless you have a fairly recent and higher quality
console (which most high schools don't) you are going to be in a world of pain programming those Martins. Movers are sexy but they are not at all
practical for the vast majority of high school theaters.
EDIT: Why do you want a moving
wash light? The
point of a
wash light is that it washes a large portion of the
stage. Do you do a lot of concerts with a
hazer? Having the
hazer will
pick up the difference in position of the light beam in the air. Without a
hazer you won't see shafts of light moving. If your goal is to add a lot of color then I would much rather spend that $7000 on a set of
LED strip lights and light the whole
stage. If I remember right there are some moderate quality
LED strip lights for around $700 each. 10 of those will blow away the light output of 7
mac 101's.
Also note, I think just about everyone here agrees that the only
LED product on the market right now that is useful for theatrical front light are the
ETC Seledors. They are the only
LED capable of producing a good quality white light as well as subtle pastel colors. All the other
LED fixtures are awesome for dramatic backlight and downlight but you don't want to shine them on someone's
face from the front. The Seledors are also very pricey.
Finally consider Elation
LED's. They've been working really hard to improve the quality of their products for about 3 or 4 years now, especially in the area of
LED's. No they don't have the prestige of the
Martin name, but there are still some really bright
LED products that are respectable and give good bang for the buck.
