I'm not sure what the spec on the LEDs he used are. But should you want to double check his resistor choices you can use an LED calculator.

Don't resistors convert electricity into heat?
Isn't that kinda defeating the purpose of the electricity savings from using LED's anyway?
Not being smart here, I'm genuinely asking.
Obviously there is still an economic advantage in never having to change the bulbs again, but damn, it's only a very small amount you're saving, and that's if you changed them ALL on scheduled intervals.
