In other words, brightness tells us how much light is being radiated by a particular light source. In the past, we have associated brightness with the power consumed. i.e. 60 Watts vs. 100 Watts. The principle that an increase in a light’s power [...] More Color Rendering Index Color Rendering Index (CRI) is the measurement of how faithfully a light source reveals the colors of objects. The index range is from 0 to 100. The higher the CRI, the better the color accuracy. CRI is an important lighting feature for skin tones, decorating, merchandising and more. For example, lighting used in a grocery or [...] More Color Temperature Color temperature is the degree of warmness or coolness of a light source, measured in kelvins (°K). Warm light is in the lower temperatures (2,700-3,000°K) and can appear yellowish, similar to a standard incandescent bulb. Cool light is in the higher temperatures (4,000-6,500°K) can appear more bluish. The color temperature is the color of the light [...] More Closet-Rated Certified We provide a full range of Closet-Rated Certified solutions for projects of all sizes.

PWM is a very common method of dimming LED lights that works by very rapidly turning them on and off (pulsing) for periods that visually appear as a steady dimmed light. We adjust the brightness level by adjusting the percentage of the time the lights [...] More Scrambled Pulse Width Modulation What is Scrambled Pulse Width Modulation (S-PWM)? S-PWM is an enhanced version of normal PWM signaling. This new technology has been patented in several countries due to its innovation and ability to reduce appearance of flickering in high level recording. How does it work? The duty cycle of each period is split or “scrambled” into several sub-pulses [...] More Tunable White Lighting What is tunable white lighting? Tunable white, also known as color tunable, lighting is white lighting that can be adjusted across a range of color temperatures. See the “Color Temperature” page for more information about the definitions of white light terms. How is it possible to change the color temperature of a white light? In strip lighting, diodes [...] More 11235 West Bernardo Court Suite 102 San Diego, CA 92127 Phone: 888.880.1880 Fax: 707.281.0567 Contact Us Sign up to receive news and new product email updates from Environmental Lights Sign Up for Our Newsletter: SIGN UP About Us Our Company News Testimonials Professional Inquiries Request a Quote Reseller Certificate Download Catalog Resources FAQs Lighting Terms Glossary Customer Service Returns Shipping Policy Warranty © 2021 Environmental Lights, LLC.
