MR16 Tru-Aim IR low voltage halogen lamps have all the advantages of standard MR16’s, with significant reduction in energy consumption (20W = 35W, 37W = 50W, and 50W = 75W) . The UV-control capsule combined with IR coating eliminates UV-B and UV-C radiation. Average lamp life 5000 hours. Axial filament for exceptionally smooth beam pattern.
