No, but ask them what their CRI (color rendering index) is. This is an indication of color accuracy, or fullness of spectrum, and dictated solely by the phosphors used in lamp manufacture. Phosphors are not cheap. Bulbs that are cheap, usually are lacking, especially in the most expensive ones. You ususally get what you pay for! JMHO
