Lions Den

February 28, 2010

We have been asked to study enterprise-wide lighting by the facilities group at Columbia University. As an example of the energy reduction we project, the Lobby pictured below uses (48) downlights conservatively estimated to burn 3.88 W / SF to achieve 18 FC at 36″ AFF. Our solution will deploy (10) 39W medium distribution MH fixtures with 82 CRI lamps consuming 0.42 W/SF.

Here’s an unsolicited comment from the school’s energy manager in reference to our 50+ lighting projects completed at Columbia University:

“Sal –

I’m a fan and I would gladly refer you to anyone who asks for a lighting consultant.  Stay in touch –

Jennifer”

Lighting Links

* Organic LED (OLED) are produced by sending a current through an organic film as thin as 100 molecules across, with a potential energy efficiency advantage of 20:1 versus LCD displays. A professor at MIT explains the concept with a glowing pickle.

* Graphene lighting comprised of light-emitting electrochemical cells is being developed by US and Swedish scientists. Is this the next generation commercial lighting technology?

* White LED yielding 208 Lumens per watt at 4579 Kelvin color temperature has been achieved under laboratory conditions.

* Koenig’s Sphere, the sole sculpture to survive the WTC collapse, has been reinstalled in Battery Park City and lit by OSRAM Sylvania.

* Downtown’s streets are among the safest in New York, thanks in part to 100 streetlights installed by the Downtown Alliance.
