I bought these indoor spotlights to replace some incandescent bulbs which have performed well and provide a natural spectrum of light in our downlights. These are the lamps we use when cooking, but the existing spotlights are nearing the end of their useful life. I wanted to use LEDs to save power, but going to a cool 5000K or 6000K color temperature and/or lower brightness would be an undesirable step in reducing lighting quality. with Bioluz based on a color rendering index (CRI) of 90. I was not disappointed. The color spectrum is very close to its incandescent neighbors - I find it even better than the floodlight it replaced. It's also a bit lighter. I am very satisfied - it is exactly what I was looking for! Highly recommended in work areas or rooms where an LED is desirable but good color legibility is important.
