MaxLite. Designed to look like a 6-inch recessed downlight trim kit, the Faux Can is actually a flush-mounted CFL downlight, helping to avoid the heat problems associated with recessed cavities, says the firm. The 26-watt, Energy Star–qualified fixture is available in dimming and non-dimming versions. It requires only a 4-inch hole for a conventional junction box, which can easily be air sealed and insulated, reducing air infiltration and exfiltration. 800.555.5629. www.maxlite.com
