Color-tunable lighting is an exciting and relatively new lighting technology that affords the user an ability to control light color to adapt, soften, and elevate human experiences and environments to particular functions throughout the day, on demand.
The science of measuring light, photometry, specifically applies to light in a space. Photometrics gauges how humans perceive light — its coverage area, where light cuts off and the intensity of light in relation to distance from the light source. In practical terms, photometrics shows whether a lighting plan meets the qualitative and quantitative lighting requirements for a project.
Art can use light to convey an emotion, mood or thought, transcending language. Artists have always used light to emphasize certain aspects of their works of art. How light bathes a basket of fruit, for example, or shines on a pearl earring, can accentuate an art work’s attributes. The contrast of darkness with lightness can be alluring. In modern art, only the medium has changed.
For the versatile, upscale look, designers often recommend trimless recessed lighting. The term trimless recessed refers to recessed lighting which contains no visible trim ring. The installation of trimless recessed lighting is more involved. Here are tips we believe will help ensure a clean, professional installation.
Unlike wireless lighting systems like Wi-Fi, Bluetooth Mesh is designed for large collections of devices, numbering into the thousands. Switches, HVAC, sensors, light fixtures, and shades can communicate with each other by forwarding a message, or command, across all the devices in that Bluetooth chain until reaching the destination to perform said operation, (i.e. turn ON the 3rd floor office lights). The communication, instead of passing through your WiFi router, comes from the originating device and travels from light fixture to sensor, to AC unit, to any other chain of Bluetooth Mesh enabled devices, like a Bluetooth highway or a body’s central nervous system, until the command reaches the lights on the 3rd floor.
The Chicago Department of Buildings recently announced that energy design requirements for building projects in Chicago have been updated as part of the city’s multi-phase code modernization process. For permit applications started on or after June 1, 2019, the Chicago Energy Conservation Code (Title 14N of the Municipal Code), based on the 2018 edition of the International Energy Conservation Code, published by International Code Council, Inc., will now apply.
This is the first post in a new series about essential commercial and architectural lighting terms. The terms, which will be presented in sets of five terms per post, are curated. The terms in this post: CRI (Color Rendering Index), Color Temperature, Bluetooth Mesh, Architectural Lighting and UL Vs. ETL Listing.
Our relation to light as humans is complex. Though many of the effects of light on our biology are still unknown, there are several we know and understand. Light also plays a major role in regulating human biological responses, including our internal body clock or circadian rhythm.
