SKUNKWORKS MEMORANDUM
TO: THE CG&S UNIVERSE
FROM: STEWART DAVIS
SUBJECT: CG&S LIGHTING STANDARDS
DATE: 11/4/2009
CG&S LIGHTING STANDARD
I like to think that we do a pretty good job of lighting design. For many years we have held the goal of setting a design studio [The Skunkworks] standard light fixture specification. Our intent is to simplify and standardize the electrical fixtures used in our projects, thus saving design time, increasing efficiency, and reducing callbacks. To date, this goal has proven elusive. One complicating factor is the ever-changing energy code requirements for residential lighting. Clearly, incandescent lighting can no longer serve as our baseline technology. This strikes me as a good time to set our office lighting standards based upon more energy efficient sources.
This shift poses some practical challenges for us, as most of us hold incandescents near and dear to our hearts. To keep our clients happy while meeting new, more stringent energy codes, we need to find efficient sources that act like incandescents. They won’t like higher initial costs, but they will like the energy savings, no more heat lamp effect, and long lamp life.
To that end, here is a wish list. Our new friends, the compact fluorescent lamp [CFL] and light emitting diode lamp [LED] would:
• Be fully dimmable using common dimmer switches;
• Have natural, pleasing color rendition and color temperature;
• Be more or less instant-on, with no long “wake up” period;
• Would fit into small aperture recessed fixtures [3” or 4” diameter] for architectural “crispness”;
• Would be recessed into fixture, or otherwise shielded, to minimize lamp visibility and the resultant unfriendly glare;
• Match brightness of similar size incandescent sources;
• Be reasonably affordable.
Experience has shown that meeting all of these criteria can be difficult, perhaps impossible. But I’m not giving up! Through this Memo, I’m officially asking our architects, our electricians, our lighting reps and suppliers, our design consultants, and our clients, for guidance.
Onward!
