Hey PE -
EDIT - GOT your PM, so appears your 'issue' is fixed (?)... I can still PM Admin, for you, if you'd like...try out some more, and lemme know if they 'get thru' or not....
Well, that sounds good... you just might-be a 'candidate' for an Install / System, then...Even-so, see the 'suggestion', below...
RE: the lighting, also - sounds-good, as-in, the darker you can make the 'area' immediately in front-of (but, importantly, too, behind...) the laser-source, AND, provided you can have a decent amount of 'atmosphere' (haze, etc) you might be able to get away with some 'lower powers'... but, really, it would always be better to get as MUCH laser-light as you can possibly afford - you can always 'turn it down' / cut it 'back' / have it play
a 'less-dominant role' - but if you don't have enough, well, you've already stated you want to 'avoid disappointment'...
Like I said in the PM, it also depends on your 'goals' for the laser(s) - are they just 'sprinkles' on the sundae'or are you expecting them to really 'shine' / be a 'wow-factor'? And whatever graphics you plan (even if minimal) - how 'important' are they to the Event - do they need to be really, nice and 'snappy-bright' (ie, for a Sponsor or an Artist / DJ, etc) or, are they truly more 'terciary' / less-important? In-all - are the lasers just 'another fx' - or do you want them to be a 'star of the show', as-well?
That-said, 2 Watts of green in that space will be the WOW you need... if they're 'just another fx', well, 1W is probably fine... but, most-likely, there isn't going to be much of a 'price-break' between 1 and 2 Watts, cause, unless the Sho Co is bringing-out a 20 Watt monster, that should not really factor into 'what it takes' for the Co to come-out and set-up - same effort, whether it is 1 or 2 or 5 Watts... typically, where you'll start to see the $$-signs add-on, is for multiple-systems, high-power systems (like 10W or more...) or lots of 'add-ons' (really-complex bounce-mirror arrays, scrims, etc, etc..) Though, often, a Co. will just make you a 'package-deal', either based on a 'flat-quote', or, whatever your 'budget-cap' is.... (for $X, you get this and this and this...)
Unless you have a Variance to perform your own shows, any Co 'renting' you lasers (if it puts-out over 5mW) will also have to supply an Operator - they should NOT just rent you the Gear, because in order for a Variance-holder (assuming they properly have one..) to maintain its' validity, the performances need to be under the constant supervision of a Qualified operator, (working under the Variance) as-to knowing the Regs (what 'constitutes' "safe" vs "not safe"...) AND maintaining safety throughout the performance... This is part of the 'value' hiring a Pro Co., comes-with...
RE: Cost for 2W (green or full-color...) well, my suggestion would be - #1, establish 'what are your "goals" for the lasers (this helps define what system 'best to use') and #2, unless you are talking a purchase-consideration - why-not just *hire* the lasers-out, this first year - and 'see how it goes'?![]()
This way, #1, you don't blow $10-15-20K on a system / controller / etc, etc, etc - only to 'discover' that it really wasn't the 'right' system for your needs / goals / space, and #2, working with a Pro, will allow you to learn, alongside the Co / Operator, whom can explain all the ins and outs of things, so, if, down the road, you do-decide to 'DIY', well, you'll have had some 'experience' under your belt, 'riding shotgun'...
Hope this helps...
