The Quasar Science Q50R Rainbow LED Duo Kit includes two 50" LED tubes that feature ultra powerful color control and creative special effects. Each lamp is equipped with an onboard digital interface that gives you control over light intensity, temperature, hue, and saturation. Go from candlelight to daylight and everything in between. Independent 2000-6000° diodes provide the full range of high-quality broad spectrum lighting. Enjoy a full 360° palette of highly-saturated color or mix in white light for soft pastels. A number of presets make creativity a breeze. There are presets not only for colors (blue, cyan, green, yellow, orange, red, magenta, and purple) but also for lighting effects, including fire, police light, strobe, paparazzi, and more. These innovative LEDs, with their cross-fading abilities between RGB color mixing and white light, are the ideal solution for adding unique lighting to video and photography projects.
