How to choose Vinaco MR16 Bulbs
Check for a transformer
Landscape lights and many track kits run on 12V. If the fixture has a transformer and the bulb has two thin pins, you are in the right aisle.
Pick the wattage the fixture allows
20W, 35W and 50W halogen share one size. The transformer and the fixture both have limits, so add up the watts on a run.
Count the hours
For lights that burn all evening, the 7W LED saves the most. For a dimmed room, stay with halogen.
