New LED driver topology from Flotonix

A new LED driver topology can now be added to the stable of converters suited to driving LED strings. This innovation announced October 11, 2016 is called Virtual Ground Drive© and promises to exceed  existing topologies by as much as 15% in energy savings. The first product to use Virtual Ground Drive is the Portable Skylight, which will […]

Virtual Skylight vs. Tubular Daylighting Devices

The Virtual Skylight (VS) is not a luminaire in the conventional sense and is best compared to Tubular  Daylighting Devices(TDD) such as the Solatube and the Sun Tunnel. I have rounded up a comparison sheet so that one can better understand the differences, using the Solatube 290DS and the Flotonix VSP Virtual Porthole 290DS    […]

GE C-Light offers circadian control

In a move towards healthier lighting, GE is now offering the C-Sleep bulbs with BLE connectivity and an app called “C by GE”. link There is a follow the sun option with three color CCTs and three switch times defined as AM, DAY and PM. Apparently AM starts off with a very high CCT, which […]

tiling daylight

The 1 foot square virtual skylight is meant to be tiled in arrays of 2×2, 3×3, 4×1 and so on. Each tile is controlled via wifi and BTLE to coordinate a simulated sky with brilliant blue color and tunable white light. Set the location and time and forget it; from then on the VS will […]

DECO: crowdsourced cosmic ray detection

Justin Vandenbroucke University of Wisconsin—Madison assistant professor of physics and a researcher at the Wisconsin IceCube Particle Astrophysics Center (WIPAC) – See more at: link The Flotonix PocketPb will also be a sensor network for cosmic rays with a specific purpose: to detect heavy metals in our drinking water continuously and automatically. The science behind this is […]

Natural skies are non-uniform

Because natural skies look more like the picture on the right, a simulated sky such as in the virtual skylight benefits from a single lit edge. The unique Evonic material in the vs allows color stacking so the ideal design might place a warm 2700K edgelit panel on top of a 6500K panel lit from […]
