Looks like you could torch a wide swath with that dude. 18, 3-watt LEDs would probably put out much too much light, at least for most of the venues I do. If you take the approach of wanting to just cover wallspace in color then this would be just the ticket. However, at least from my experience, a big part of the allure is not just mass-painting wall space. A lot of the visual appeal is having that sexy "V" going up the wall, paired with the non-colored space in the gaps. You'd also have to contend with the brides who would look at your quote for say, 6-10 of these, then look at my quote with 20+ fixtures and I guarantee that in that scenario I'll get the contract 90% of the time. Brides don't understand "more powerful" or "wider coverage" on fixtures. All they get is the number of units.
