We use them on our porch. They produce so much light that our security camera stays in day mode, giving us a color image of our porch and everyone who walks on it. Obviously these are new bulbs so I can't comment on their durability. We first tried a colored daylight bulb of the same wattage and it was hard on the eyes and didn't put out as much real light. I would recommend these lamps to anyone who wants to produce a lot of light that is pleasing to the eye.
