I put these in our exterior house lights, and my husband thought the neighbors might call the fire department - they look that realistic!!! They don't give off a ton of light, but the ambiance is cool. My teen son promptly removed these and put them in his room - so now we're fighting over them! I personally think these are better for a specific event, like Halloween or maybe an outdoor tiki bbq type thing, but I wouldn't use them all of the time. They're plastic, but they seem sturdy and work GREAT!!! Highly recommend.
