What is the difference between Centric and NorthLux lights, since they each have 5000K and 6500K temperatures?

What is the difference between Centric and NorthLux lights, since they each have 5000K and 6500K temperatures? Do these have the same spectral output and are simply the same lamp but in different product families? For backlighting, 35mm slides when photographing (digitizing) which would be better, a 6500K from the Centric or Northlight groups, or the 5600K Filmgrade since it is supposed to match the camera sensor more closely?

For our A19 lamps, the CENTRIC DAYLIGHT products and NorthLux products both have 95 CRI, but have slightly different color point tolerances, with the latter being more precisely calibrated for color matching and viewing applications.

Specifically, the NorthLux 5000K meets the ISO D50 color viewing standard and may be a preferred option for your camera application. (The products are distinguished by their part numbers, which are PN 4005.50 and PN 4005.D50, respectively).

Regarding color correction, the closest match to D50 with our NorthLux product will suggest that few to no color corrections would be necessary because most camera systems will have the D50 color point likely pre-loaded as their calibration point.

Our FilmGrade A19 is another option that provides the same 95 CRI spectral quality, with a slightly higher blue component compared to 5000K. The 5600K color point is commonly used for photography and cinematography applications and is commonly chosen where ambient lighting conditions are also calibrated to a 5600K color environment.

Given the 95 CRI and high R9 values, the color spectrum of the NorthLux 5000K has sufficient coverage for all wavelengths that the camera sensors are calibrated to.
