Holiday LED lights powered by off-grid sources
Emphasizing the green credentials of LED lighting for the holiday season, a number of schemes are using solar power and even hydrogen fuel cells.

One very interesting aspect of this installation - and almost certainly a first for LED lighting - is that the entry gate is an autonomous, off-grid installation powered by an experimental 12 VDC hydrogen fuel-cell system from Pepco.

A similar green approach has been employed by two vineyards in Temecula, California, this time using solar power to provide LED lighting for the Temeculights Holiday Festival. The organizers, the Green Lights Project, are seeking to educate visitors about California’s solar energy incentives, rebates and renewable energy credits. LED lighting has been provided by Four Seasons Lighting, Inc.
At Keyways Vineyard and Winery, LED lighting throughout over 2 acres of vineyards will be powered by a Mobile Solar Power Station that has been provided by Akeena Solar for the purpose of public education and the promotion of solar photovoltaic power.
The concept of the "wireless Christmas tree" was conceived by Mark Stone, the MD of Plantscape—as a winter enhancement to the company's summer trade in decorative urban planters and street furniture. Plantscape came to Brillianz to develop a solution allowing them to provide a decorative lit tree which would operate throughout the festive season with no external power connection.
The units consist of two "half trees" that are attached around a lamp-post. The 60 LED lights use only one tenth of the electricity that conventional bulbs would consume, and are powered by a small solar panel sitting on top of the tree like a star.
The BBC reported that the town of Porthcawl in Wales expects that its 88 solar-powered trees could save the community £10,000.
