Ketra is a new company from Austin that stopped by our office. They specialize in a control system that allows you to have total color control of their fixtures as well as limited control of fixtures from other manufacturers. Ketra's control box can be used on its own or incorporated into a larger control system coordination. Ketra offers both a linear fixtures and LED PAR lamps. With their control system you can change the color temperature and CRI along the black body curve as well as static colors. Output is maintained regardless of color temperature. Their proprietary software is available to download and program scenes and settings for your lighting design, or fixtures and lamps can come preprogrammed from the factory.
Working on a closed loop system, Ketra allows you to calibrate color and temperature amongst the fixtures providing consistency across the board.
They said that they are developing a 3" downlight and hope to release it soon. We will have to see what the final product looks like, but we tend to be a little hesitant when companies that are traditionally focused on other aspects of lighting such as controls, try and get into the downlighting game.
