T8 and T5 lamps achieve both improved color rendering and high efficacy by employing rare-earth phosphors. The correlated color temperature (CCT) and color-rendering index (CRI) of the lamps is controlled by varying the selection of phosphors. The CRI of T8 and T5 lamps can be specified from 70 to as high as the mid-90’s. Every lamp manufacturer has a product coding system denoting CRI, which may require a catalog to decipher. For great lighting quality, specify a CRI of at least 80.
