The revolution is pretty much complete. Light bulbs are going the way of the dinosaur. Sure...there will always be a place for them, but LED lighting is taking a commanding lead in nearly every lighting category. Today's LED lighting is matching the brightness (the main complaint against it) of bulb lighting, and has clear advantages over it's fading competition.
LED lighting takes a fraction of the wattage that bulb lighting requires, cutting you electricty costs by as much as 90%. LED lighting also creates virtually no heat, meaning your ventilation system has one less thing to overcome and your performers and guests won't be broiling in the glow. Also, LED lighting can be as simple as a whilte light, or come with nodes of 5 different colors (white, amber, blue, red, and green) allowing you to create almost any color with no need to use gels.
LED lighting fixtures also cost about the same as traditional lighting fixtures so the initial investment is pretty much the same. If you're replacing fixtures over replacing bulbs, the average user sees the complete investment returned in electricity savings in less than two years. Plus, no more climbing ladders to swap those bulbs. Professional LED lighting is rated for 50,000-100,000 hours of use before failing.
So, make the investment in something that's going to actually work for you rather than against you. LED lighting from Midwest Pro Sound and Lighting can be used indoors and out.
