 My name is Eric Huffman. I'm the Director of Daylighting Sales for SunOptics, which is a division of the QD brand. SunOptics is a manufacturer of skylights, so we make daylighting systems to bring natural light into space and eliminate the need for electric light during the day. A typical product for that application will be a large commercial skylight, typically 5 foot by 6 foot or bigger, up to 5 foot by 10 foot, depending on the trust spacing of the building. And so we would space those in the building very similar to how you do an electric lighting layout. So we consider these wireless light fixtures that our source of power is 93 million miles away and it is what allows us to bring in that natural light into space. Of course they would still install electric lights for use at night, so we don't eliminate the need for electric lights only for certain hours of the day do we do that, so we'll be able to turn them off. We combine them with a control system to automatically turn the electric lights off when it reaches a certain light level in space. A typical space, one of our biggest clients is Walmart and their typical design will have about 5% of the roof space covered in skylights to meet their light level target of a nice highly lit retail space and lower average turning off their electric lights almost 3,000 hours a year. So their payback of their return on investment in the skylights is usually less than 2 years. Well we just launched a new product aimed at the school and office market, so it is that drop ceiling application that you had mentioned, the tubular type device. So that's really the most exciting thing we launched. Being part of Acuity, of course they have a whole breadth of products from LEDs and OLEDs and all types of new control systems that are introduced in this year as well.
