Pure MR3 & Pure MR6

The Pure MR3 will directly replace a 20W halogen MR16 when accent lighting is what you seek, while the Pure MR6 can replace up to a 35W halogen MR16 where a lot of light is needed. Whatever MR16 type you are currently using you can replace with the Pure MR. Available from 15-degree spotlight to a 60-degree floodlight, the Pure MR6 truly is a versatile choice. The Pure MR carries all the typical safety circuitry a standard halogen would, including: over current protection and reversed polarity protection. It also carries the low voltage safety standard of CE and it is an environmentally efficient product carrying the trusted RoHS branding. This MR16 3W or 6W bulb is also rated to last you up to 50,000Hrs and is a safe choice for do-it-yourselfers as it operates at 12 volts.
