Fire and Light!Since the beginning of history light and fire have been related. If you wanted to see in the dark, you would "light" something on fire. In 1879 when Thomas Edison invented the electric light bulb, it was 98% heat. What Edison really invented was a way to burn a carbon filament without burning it up. Inert gasses replaced vacuum, tungsten replaced carbon and halogen convection cycles mechanically scavenged tungsten atoms and returned them to filaments, but this all simply made burning something without burning it up a bit more efficient. Incandescent light sources remain 94% IR (heat).
One problem with this is that IR photons are responsible for 40% of the fading in organic materials (National Park Service data). Another is that heat from lighting drives temperature cycles, especially at an object's surface. Mechanical stresses of differential expansion and contraction crack art and spall minerals. Paintings under halogen track lighting can show surface temperatures 5 to 10°F above ambient. And, at room temperatures, a temperature change of 10°F equals a shift in RH of 15%. Hot and cold, expand and contract, dry out and absorb moisture (and everything chemical in it). Leather in urban environments can absorb 1% of its weight in acid every year due to these RH cycles and the pollutants in urban air.
Fluorescent lights are much more efficient than incandescent, about 70% heat (and 6 to 8% UV). That reduces the damage by 18%. LEDs have similar efficiency, they just move their heat emissions to a chip, circuit boards and power supplies, hence the fins and the fans.
A NoUVIR fiber optic projector also has fins and a fan, but the projector is remote from the luminaires emitting light. All of the IR is removed at the projector. Each of the adjustable focus, amiable, perfect color, fiber optic luminaires is absolutely UV and IR free. You get all of the visibility with only 5% of the total energy of a halogen source and your artifact life increases by 20 times or more. Remember, that's not just hugely reduced fading. It is also reduced mechanical stress, reduced RH cycles, reduced contamination, and reduced cleaning.
Beautiful lighting, perfect control over aim and focus, multiple protections, substantial energy savings and great service. What's not to like? NoUVIR... we invented museum lighting.
