Alan,
My light's come on in the order you mentioned but for 4 bulbs instead of three. I don't have it spaced an hour apart though is more like 30 minutes.
I don't notice any benifit's other than I think it looks cool when the 2 radiums are on and then you get the single daylight bulb firing for a very cool effect
