The Best Solar-Powered Walkway Light.

This solar walkway light scored highest for brightness of light, duration of light, and durability in tests conducted by the Hammacher Schlemmer Institute. Solar energy collected by the large 4 1/2" x 4 1/2" solar panel--the largest of all the models tested--is converted to electrical energy and stored in the light's Ni-Cad batteries. Housed in a durable 100% stainless steel rust-free frame with a clear, high-impact polycarbonate lens, two high-output LEDs generate 6.8 watts of light, unlike the 1.2 watts generated by other solar lights, and produce a soft, ambient glow for up to 13 hours, three hours longer than the nearest tested light, when fully charged. The light's built-in photo sensor automatically turns the light on at dusk and collects solar energy during the day. Includes stainless steel ground stake. 23 1/2" L x 8 1/2" Diam. (3 lbs.)

The First Solar Powered Robotic Pool Skimmer.

This is the first solar-powered robotic pool skimmer that autonomously navigates a pool and removes leaves, grass, and insects, taking the toil out of skimming a pool and reducing strain on pool pumps. Two solar panels on top of the skimmer collect solar energy and store it in the rechargeable NiMH batteries. Dual, turbine-like paddlewheels propel the device as it continuously courses across the water and send debris to the skimmer's filter. Four wheels on the side panels allow the skimmer to turn when it encounters a pool wall and navigate along the perimeter where dirt often collects. An internal microprocessor monitors the skimmer's power and prods it to "seek" sunny areas of the pool to recharge the batteries. When the unit enters the sunlight, the microprocessor slows the rear paddlewheel, allowing the solar panels to collect optimal energy and, once the batteries are fully charged, the skimmer resumes the cleaning process. During the evening or cloudy conditions, the unit automatically reduces its speed to conserve energy while continuing to clean the pool. If the skimmer becomes clogged, it will automatically reverse the rotation of its paddlewheels to dislodge the stubborn detritus. The skimmer holds two 3" chlorine tablets that slowly dissolve as the skimmer moves across the pool. The filter removes and can be cleaned with a garden hose. Operates for 8 hours on a full charge. 6 1/4" H x 20" W x 23" L. (8 lbs.)

The Place Anywhere Articulated Solar Light

This articulated solar light has two independent telescoping stalks-similar to a snail's ommatophores-that swivel 360, allowing you to cast light in any direction once it is mounted to a wall or post, or staked into the ground. A central solar panel provides power to the lights, which each use ten LEDs that generate a bright spotlight up to 20' for nine hours. An included remote control allows you to turn the lights on and off from up to 50' away. 111/2" L x 6" W x 33/4" D. (3/4 lb.)

The Solar Powered Lighted Patio Umbrella.

This solar-powered patio umbrella provides a nighttime glow over your patio table for up to eight hours without the need for extension cords crossing your deck, patio, or lawn. Under a generous 9' canopy made of durable polyester treated with a UV- and water-resistant coating, the umbrella has 24 LEDs built into the six spreader rods that attach to the ribs, providing an ambient glow for late night entertaining. A sealed weatherproof solar panel at the top of the umbrella recharges a Ni-Mh battery which provides power for the LEDs with an 85% efficiency rate, unlike lesser solar arrays that only operate at 50-55% efficiency, resulting in the longer eight-hour illumination time; manual on/off switch included. The sturdy powder-coated aluminum pole and frame are corrosion-resistant, and an aluminum crank makes opening and closing simple. The LEDs are rated for 100,000 hours of use, and provide an appropriate glow for evening dining and conversation. Fits standard patio umbrella base (not included). Brown. 94" H x 8" Diam. (15 lbs.)

The Solar Triple Carriage Lamppost.

This three-light carriage lamppost does not require complicated wiring, it simply stakes into the ground, and provides energy-efficient, bright light. A larger version of the Best Solar-Powered Walkway Light (visit hammacher.com and search for 74160), the carriage lamppost has three discreet solar panels that recharge the Ni-Cad batteries during the daytime, while a built-in photo sensor automatically turns on the lights at dusk. Each light has two high-output LEDs housed in a durable 100% stainless steel rust-free frame with a clear, high-impact lens. The LEDs generate 6.8 watts of ambient light that lasts up to 13 hours. The nearly 7'-tall carriage lamppost can be staked into soil or permanently affixed to concrete (hardware included). 79" H x 18 1/4" D. (16 lbs.)

The Solar-Powered Light Show Wind Chime.$39.95

This wind chime has four solar panels that provide power for an LED contained inside a crackled texture glass sphere. The LED progresses through seven colors, one color every three seconds, and its light is refracted through the glass, creating star-like patterns on walls and floors. The sphere also acts as a striker for the five aluminum chimes that hang from the canopy, producing a gentle cascade of tones in breezes. 22" H x 8" Diam. (2 lbs.)
