A 120 to 150 W transformer suits a short run of LED path or spot lights, such as a walkway or a single garden bed. Budget units from DEWENWILS, Malibu and WILAWELS cost about $60 to $80 with a photocell and timer built in. Contractor units from VOLT, FX Luminaire and Unique Lighting cost three times as much and earn it with long warranties and sturdier cases, but some leave the timer to you.
