LMT says it has redesigned its line of low-voltage LED post caps to make them more reliable and less expensive. The lights draw standard household current but convert it to 12-volt direct current. Transformers come in two models: The 12-watt transformer will power as many as 16 lights; the 50-watt model will run 65 lights and has a programmable power supply and a dimmer. Components plug together, so there’s no cutting or crimping of wire. Post-cap LEDs come in a variety of sizes and several styles. LMT Mercer Group, 888.570.5252, lmtproducts.com
