I needed a bright bulb for street lighting. Considering I run it every night, I wanted something energy efficient. To be honest I'm not exactly sure if this is really energy efficient as I can't easily measure it but I'll take her word for it. Given the advertised lumens, I figured the bulb would be a lot brighter and brighten up the night sky, but I wasn't impressed. It's still light, but not what I expected. It is still considered expensive for two lamps but appears to be the lowest price of its kind.
