The 12V EmeryAllen MR16 retrofit lamp is an energy efficient alternative to 12V halogen MR16 lamps. It is suitable for use in most 12V GU5.3 MR16 fixtures. Its long life (25,000 HRS = >10x standard bulbs) is ideal for track lighting, pendants, ceiling fixtures, and outdoor lighting applications. The 5.0W bulb offers similar light output to a 12V, 35W halogen (300-450 LM)
