Thank you for all your excellent scripts. I wish all scripts were written to the same quality and easy of use as yours. Thank you.

In your description you say that using other methods besides the control light is less effective. How is it less effective? I can't tell a difference but if there is a difference I'd like to decide which method is best for me. I prefer not to use a control light as it is a light that might get moved or destroyed and then the script wont work and I have to remember which one it was or put in a new one and I like things simple and clean. So what is the difference?

Thank you for taking the time to read and reply.
