To be honest I was a bit disappointed with the brightness and color of the bulbs. In hindsight I preferred these bulbs to the higher wattage ones so that's up to me for the brightness. I would disagree that these bulbs have 3000K / warm white light. They are whiter than warm white. In general I needed replacement bulbs and LEDs because of their efficiency (and this was my first try) so for the price they were right. I haven't seen any obvious issues with their quality out of the box. I would just check the brightness and color you need when buying lightbulbs. If there are any problems, I will report on the durability.
