I use these in Victor flea traps as we have a house cat, a house cat outside and an adorable cat that only comes to eat when the weather is really nice bad. In winter he prefers a garage with a heated bed. So with traffic come fleas. I prefer the 7 watt ones as they give off more heat which is better at attracting fleas to the traps. Can't comment on durability since I just received it, but the 130 volt rating indicates a quality bulb. The price is also better than local stores.
