But let's be generous to the purveyors of this device, and assume that
it's 20% on average. Further assume an average total cost of $125/month.
That's $25/month for lighting. If this device can save 40%, that's $10/month,
making it 200 months = 17 years before you recover the cost of purchasing it.
Add another couple hundred bucks or so for installation by a licensed
electrician, and you're looking at a payback period of pretty near twenty
years. At the lower end of their projection (30%), the period approaches 25
years. And if your lighting costs are only 10% of your total, instead of 20%,
it's nearly 50 years.

Good analysis. That sure looks like a scam to me.
