Benefits of LED Power reduction Heat reduction Low maintenance, no lamps to replace No need for dimming No more gels to replace Thousands of colors at your fingertips, flexibility

Benefits of Incandescent Great warm color temperature Still the best way to get very soft, even light Best lumens per dollar value No computers, data, drivers, etc. Give them power and they work.

Choosing The Right LED What are you trying to light? If you’re lighting for effect, what effect are you trying to create? White (and what color temperature?) or color? How picky are you about color or a specific white color temperature? (3, 4, 6 and 7 color options) What is your throw distance? How much area do you want to light?

How does this relate to House Lights? Benefits of LED House Lights Low power, low maintenance fixtures (no lamps) Generally no dimming required Can potentially control each fixture Variety of white color temperatures, look great FULL COLOR!!!!

Concerns With LED House Lights Most LED lamp replacements are not bright enough yet Not all LED House Lights are fully dimmable Use fixtures without fans (convection cooled) Professional, theatrical LED house lights want DMX run to each fixture (labor cost) Most electricians and architects don’t understand fully dimmable, theatrical LED house lights yet. Choosing the right beam spread They are significantly more expensive up front, but pay for themselves in 2-5 years (depending on usage)
