“In the art world, the concentration is generally on high color rendering, which LED can do well,” said Lightswitch Partner Avraham Mor, IALD, LEED AP, IES. “However, the question is, how do we optimize color temperature? We were looking for an LED solution that would give us flexibility in temperature without sacrificing exceptional color rendering.”

In order to select the right LED solution, Lightswitch and the Art Institute of Chicago compared LED sources from a number of different manufacturers in a series of mock-ups. Lightswitch focused each LED source on both a painting and an object to produce identical illumination levels and to compare each LED to the halogen sources currently used throughout the museum.

Lightswitch facilitated a side-by-side mock-up illuminating four works by French painter Claude Monet in which Ketra was compared to the museum’s existing halogen lighting solution. Lightswitch designers matched color and light levels between the wall and the paintings using Ketra’s Design Studio software and their own visual perception. Afterwards, they used a Sekonic light meter to compare the color rendering, illuminance and spectrum of the light sources illuminating the paintings. Twenty Art Institute staff members were present to review the final results, including art curators, exhibit design staff and facilities staff. It was unanimously agreed that Ketra lighting was the correct solution for the museum going forward. The museum will be proceeding with a Ketra system for their newest gallery renovations, and will continue to integrate Ketra into other spaces around the museum.

“We have been tracking the development of LED for some time, but we had not found a product that showed the art to its best effect at an affordable price,” said Chief Operating Officer of the Art Institute of Chicago David Thurm. “Ketra now makes it possible for us to shift to LEDs. We were impressed by the quality of the light and the ability of the LED to self-correct to avoid a degradation of quality over time. Economically, it also makes a difference that we can use our existing fixtures without modification.”

Ketra’s technology is ground-breaking in its consistent accuracy and best-in-class optics, as well as its system of continuous closed-loop optical and thermal feedback for color point maintenance. Ketra’s unique combination of calibrated, tunable lighting, wireless control and energy savings enable the Art Institute of Chicago to have all the features they were seeking in a lighting system.

“We had situations like this one in mind when we developed the patented driver-chip technology inside our products,” said Ketra CEO Nav Sooch. “It will ensure that color never drifts with time, and the works displayed in this prestigious art institution are always beautifully rendered.”

At this week’s LIGHTFAIR® International in New York City, Ketra was awarded ‘Best Conventional Retrofit and Replacement LED Lamp’, which is a testament to Ketra’s innovative technology. An esteemed panel of judges from across the industry was tasked with considering thousands of product submissions, and chose to award Ketra with this category’s highest honor. Ketra’s submitted product was their mainstay PAR38 lamp -- the S38 -- a fully tunable, single point source lamp complete with internal wireless radio, and closed loop optical and thermal feedback for color point maintenance; available in multiple beam angles and lumen outputs.
