Those numbers are NZD, and from less than 2 months ago. :) To convert to USD, multiply by 0.8. I just looked on the home hardware website, and they don't sell any MR16s that are more than 6.5W. The 12W bulb is a 650 lumen and sells for NZ$13. However, a CFL goes for less than NZ$4. That $9 will buy you a lot of electricity. At 3hrs/day, and NZ$0.25/kwh, that's a break even point of ~5.5 years... I think... (6W difference in power usage between CFL and LED?) Going from a 20W halogen to a 10W led would result in a payback period of 3 years. To me, these sorts of things need to pay off in their warranty period. :)
