Using this in an exterior wall sconce with a clear glass cover and no dimmer. Works well as a replacement for A19 25w incandescent. Color and brightness is comparable to incandescent. The filament seems slightly more harsh than the A19 incandescent, possibly because it’s an a15 or just because of the LED filament, but not a real issue. Wish there was an A19 but glad to find a 25w clear a-type LED.
