55-Watt Dual Tube CFL, Full Spectrum by Dazor

The 55W Full Spectrum (5000K) CFL bulb produces the broadest spectrum of energy wavelengths, attempting to simulate outdoor daylight at noontime. The phosphors used are selected to improve color perception. Therefore these bulbs have a higher color rendering index (CRI), a rating used to represent how well a light source renders the colors of objects that it illuminates. Full spectrum bulbs are commonly used in applications where accurate color perception is most important.
