These bulbs are very bright. I accidentally bought a BR30 to replace my BR40 and I really prefer the look of the smaller recessed bulb. But I have these dimmer bulbs and they flicker like crazy. I would have blacked out a head with these. I would also like to add that the 4000K color temperature is perfect for my home office compared to the warmer color temperature. I will replace these. Seek now. Will update if I find a better bulb. UPDATE: The target has some lights and lights up. Set of 4 BR30 5000k for $9. Lumens 650 vs 850. I don't think it matters much in a room because 5000k seems brighter than 4000k so it probably makes more sense to lower the lumens.
