I use it in a small frosted glass accent lamp so when you turn the lamp on and off you see the 'filament' glow. Distracting, it does its job well with a low color temperature when you walk away and only gives off a glow. When it's first turned on, the brightness seems to spike for a split second and then come back down to the right amount of light. Overall light output seems to match the original bulb I replaced (maybe this one will last forever)
