Try to think initially that there are two types of lighting...Lights that the audience see when they look AT your show, and those lights that shine out to your audience...
For example: Lightscreens "fill-out" your show, your "on-stage presence" as it were. They act as a focal point for the audience to turn and face...
Whereas, most projection effects, such as moonflowers, datamoons, flatbeam effects etc, look very ineffectual when the audience looks towards them, but their mid air effect (in smoke) and what they produce on walls, floors, dancing punters etc, is an effect in itself.
Some lighting...eg: Ye olde worlde 60watt reflector bulb, are a little of both types of lighting...
Consider also, whether the venues that you're looking at playing will allow smoke...some hotels dont, and therefore some lasers and particularly flatbeam effects, and mid-air effect lighting is "lost" (unless you start handing 'round the cigars - dont miss out the blokes as well

)
My show (pictured elsewhere on this forum) used to have 4 floor columns, each with 12 60watt reflector bulbs in it... I built some overhead cabs for these (shown) each cab holding 16 bulbs...for two reasons...on the floor, the old columns were heating up the audience too much...baked beings...also, I was concerned over the number of kids at schools and weddings who would try to touch (remove?) the bulbs whilst they were hot...so..UP they went.
On the subject of reflector bulbs....there are even Prp's and con's over which fitting to get - Bayonet cap (like ordinary household lightbulbs - push and turn) or Edison Screw fitting. Screw in bulbs tend to work loose every few gigs during transit, but there seem to be 6 colours (at least) that you can buy ES (edison screw) bulbs in, compared to only 4 that I've found in BC(bayonet cap). Bayonet Cap fittings also have a tendency to let the bulb sit/flop about 5degrees off centre when mounted...not too noticable.
Lots to consider really....theres always Fuzz lights I guess....
