Sun Tunnel Systems, San Jose, Calif., has added the Night Light Kit to its 14- and 22-inch diameter skylights. The kit is an option that enables consumers to use the skylight during the day and a recess light at night by simply flipping a switch. The company also offers the Fan-Attic, a solar-powered roof ventilator fan that requires no electricity and reduces cooling costs up to 50 percent. It is installed on the roof and is fully operational in 30 minutes. The fan comes complete with 26-gauge roof flashing and frame, an 11-watt solar module, 12-inch aluminum fan, a UV-stabilized weather-resistant top cover and a low-voltage DC motor assembly.
