I installed 5 bulbs in my dining room chandelier which has a diffuser at the bottom but is otherwise completely open. The light is very bright. The color temperature analyzer showed 3150K, which is pretty close to the factory 3000K, and the color profile is slightly warm. The cell phone had no hatched stripes or black bars with these lights, even when very close to the bulbs. Also, the LEDs are all the same color, so there are no weird colored lines or dots on the diffuser. The light stays bright after an hour of use. These bulbs worked reasonably well with the TPLink Kasa dimmer, although they reach full brightness at the 75% setting. Make sure to calibrate the dimmer in the Kasa app to set the minimum settings.
