If Principles of Energy Conversion have taught me anything it's that this statement is most likely completely bullshit.

First of all a church would probably not be using incandesent bulbs and would use some sort of florescent or halogen. The first bullshit alarm being when they compare the numbers to incandescent..
They are free so they biggest negative is moot but the 25X and 5X are just slightly inflated... Today, LED's are about 50 lm/we while incandescent is about 15 lm/we. I don't have any good data on the lifespan but I would say thats its slightly inflated but in the ballpark. High efficiency compact fluorescents are the same lm/we output and cost a fraction of the price and last just about as long.
