This is a system of 39 RGB pendants, each of which is independently controllable by a DMX system that was installed along with the pendants, but in a remote location. The project included selecting the controller, building remote enclosures for the driver and control components, and coordinating with the site on proper wiring procedures.

High Brightness Solid Brass LED Sconce for Exterior Use
This sconce required a custom designed LED PCB to provide the desired level of brightness and lighting evenness as required by the customer. The shape also required special consideration to route the heat of the LEDs down into the base and out of the sealed glass diffuser.

This 17-tier OLED chandelier is the focal point of this spiral staircase in the lobby of a high-rise office, seamlessly integrated into the floor and ceiling. Every square is an OLED panel that is individually controlled. In total, there are 340 panels powered by 43 power supplies. Custom DMX repeaters were installed in the tiers to reduce wiring. The power supplies and DMX controller were installed remotely in specially made housings for ease of installation and thermal management purposes. All wiring between locations was coordinated with the contractor to streamline installation.

This globe is made up of one spherical geodesic globe nested inside another one. The globes themselves carry power to each LED node, so the only visible wiring is down from the canopy. Each globe is made up of 270 individual straps that are bolted together at each LED node. The end result is mesmerizing in its complex geometry presenting as a simple shape.

Starburst
This decorative chandelier was an early use of LED’s in decorative lighting. The bubble rod arms are end-lit by 24W of LED on a custom board with a purpose-built driver. At the time, standardized LED modules were rare and driver options were very limited, so all needed electronics were custom built. The rods poised unique challenges to get the right clarity and bubble density.
Icicles
This series of 2×2 tiles had custom light engines for each bubble rod icicle. A bus power supply was designed to minimize installation requirements and allow flexibility of icicle count and positioning.
