City of Seattle- Fire Station 21
Custom Applications in Functional Artwork
This installation can be found at 73rd and Greenwood
Thick glass offers an interesting medium for LEDs to shine through
The bottom 3 layers will remain "on" and the top 2 layers will activate when the fire trucks are about to leave the station, a nice visual warning to those nearby.

Coastal Transportation Inc.
Coastal Navigator
Coastal- quite possibly the first shipping company ever to use LEDs inside refrigerated cargo holds.
Benefits of LEDs in this case:
- Substantial diesel and shore power savings
-Improved safety
-Improved productivity
-Lights that do not generate much heat put less strain on the refrigeration system.
-Reduced maintenance costs
-Resilient to the severe vibrations from cargo operations and the engine
-Resilient to temperature changes (from ambient to -15 degrees Fahrenheit)
-Additional savings; No ballast means no need for the more expensive sub-zero ballast necessary for fluorescent lights
-LEDs last even longer (than 50,000 hours or about 11.5 years @12 hours per day) in cold environments
