- Thread-topic: Solux Bulb color temperature
I fully understand CCT and I'm not talking about any random 5000K bulb like
a fluorescent and how it compares to a 4700K Solux bulb. Both bulbs are
Solux, both are labeled D50, and both are essentially the same light source.
But one is closer to 5000K than the other, only with less light output
probably due to slightly more aggressive filtering. Why wouldn't that exact
bulb be preferred over the 4700K bulb in terms of ISO conformance when the
5000K bulb 1) has a spectrum closer to D50, 2) has a color temperature
closer to 5000K, 3) has a slightly better CRI, 4) has a slightly better MI,
and 5) has a slightly smaller chromaticity error as compared to the 4700K
bulb?
