An LED lamp with a high color rendering index (CRI) is disclosed. Example embodiments of the invention provide an LED lamp with a relatively high color rendering index (CRI). In some embodiments, the lamp has other advantageous characteristics, such as good angular uniformity. In some embodiments, the LED lamp is sized and shaped as a replacement for a standard incandescent bulb, and includes an LED assembly with at least first and second LEDs operable to emit light of two different colors. In some embodiments, the lamp can emit light with a color rendering index (CRI) of at least 90 without remote wavelength conversion. In some embodiments, the LED lamp conforms some, most, or all of the product requirements for a 60-watt incandescent replacement for the L prize.
