I originally wanted to order 75 watt bulbs to go with my three new outside lights ordered from Wayfair. But only one was left, do I settled for the 60 watt instead. Thank goodness I did. My outside lights have clear class, not frosted. With them, the 60 watt gives off more than enough light. The 75s would have been way too bright. I don't know yet how long they will last. But for now, they are just what I needed.
