LED DirectFit PL lamps from MaxLite convert existing four-pin fixtures to LED technology. The 13-watt plug-and-play replacement lights for compact fluorescent lamps operate off the fixture’s existing ballast. Offered in two designs to suit horizontal or vertical mounting positions, the lamps are available in three color temperatures. They deliver up to 900 lumens and consume 50 percent less energy than the 26-watt CFL bulbs they replace. 973/244-7300; www.maxlite.com.
