I have finally found the LED bulbs I have been looking for for the past 7 years. Not only are they bright, but the color/quality of the light they put out is remarkable. The color rendering index (CRI) for them is 90, which is about as much as you can get at this price point. I would be wary of buying lamps that don't have a CRI. As a result, there is no greenish or other color cast and the wall color looks as good as you imagined when you first selected it.
