What do you do after you've greened your ride and made the road a big solar panel? You tackle the parking lot, of course. That's the suggestion of the company behind the Green Spider, a way to turn down your parking lot lights. The idea is that you don't need to have all four (or whatever) lights at the top of the pole on at one time, and so:
At a predetermined interval, the Green Spider turns off up to three individual 1000 watt fixtures and leaves one remaining fixture illuminated for both code and security.
Basically, it's a big dimmer switch on a timer for your parking lot and the company promises a reduction in lighting energy costs of about 30 percent, saying the system can pay for itself in four months in some cases. About 40 parking lots in Florida are currently using the system, and company co-founder, Tony Massa, believes, "The Green Spider will revolutionize the way commercial property managers illuminate parking lots around the country."

Green Spider isn't the only group to tackle the problem of overlighting. The DOE is heading up an LED Parking Lot Lighting Working Group designed to get functional "reliable, energy ­efficient, and competitively priced outdoor LED lumi­naires more widely available in the marketplace" (PDF). Orion Energy Systems also offers "fluorescent lamps that reduce users' energy consumption by 50 percent or more while significantly increasing light levels in comparison to the legacy high- intensity discharge lights that are used in most parking lots today" (PDF).

The Green Spider Is Latest Innovation in Energy Efficient Lighting
A new, first-of-its-kind energy-efficient lighting system called The Green Spider launched this month will soon become common in lots across America. By controlling a lot's lighting during off-peak hours, the innovative product reduces lighting energy consumption and costs by about 30 percent, extends the life of existing lighting, and pays for itself in as little as four months.

"An open-access lot that is fully illuminated at 1 a.m. wastes money and energy, but a dark parking lot isn't ideal either because it may compromise safety, security and potentially violate local minimum lighting codes," said Mr. Massa, co-founder of Green Spider Energy, LLC, which developed The Green Spider. "The Green Spider is the solution."

How it works:
The Green Spider is designed to work in conjunction with existing parking lot lighting controllers, such as a photo-cell, time clock or remote energy
management system. It installs on any multiple fixture lighting pole in minutes. Once installed, The Green Spider automatically allows all fixtures to operate normally during heavy daylight and evening traffic hours. At a predetermined time, The Green Spider turns off up to three individual 1,000-watt fixtures and leaves one remaining fixture illuminated for both local lighting codes and security. At dawn, The Green Spider resets itself for the next day's lighting cycle.

During its test phase, The Green Spider was installed at a shopping center in Miami, Fla., on seven three-headed light poles. Prior to The Green Spider's installation, the center's average monthly electric bill was $1,225. After installation, the center's electric bill was reduced by 25 percent to $925.

"The savings were immediate," said Tony Massa, co-founder of Green Spider Energy, LLC. "The Green Spider will revolutionize the way commercial property managers illuminate parking lots around the country."

The Green Spider is currently used in about 40 parking lots in Florida, and the company is rolling out the patent-pending product nationally in 2010.

Green Spider Energy was founded in 2009 by Massa after seeing his clients' needlessly waste money and energy overlighting auto lots throughout the night.

Manufactured in the U.S., The Green Spider costs about $350 per unit and comes with a complete satisfaction guarantee.
