To celebrate Earth Day, April 22, PosterGarden is offering a discount through April 30 on its new energy-saving LED light, suitable for illuminating trade-show booths, banner stands and other displays.

The light, which fits on the company's banner stands and pop-up displays, stays cool, uses little electricity, and lasts from 25,000 to 100,000 hours, the company says.

The company also offers eco-friendly display products and its "Redeem Green" recycling program.
