Comparison Between 8000K Sky White and 3000K Soft White

Comparison Between 8000K Sky White and 3000K Soft White

Click to view full size image

I finally made it to Menards and bought a pair of 8000K Sky White tubes! For comparison, I also bought a pair of 3000K Soft White tubes. Here they are!

My camera is set to daylight white balance for the top two pictures. To see how blue these tubes truly are, I set the camera to incandescent white balance for the bottom picture. You can see how the 3000K tube looks natural but the 8000K is almost colored blue! Still, it is a very nice white-blue, not an ultra-cold blue-purple.

The top right picture is of the two tube packages being lit by the corresponding colored tubes. Of course, the etches are in the bottom right pictures, also daylight white balanced.

Interesting note: When I was carrying these tubes in from the car in the daylight, the Sky White tube looked slightly more blue than the Soft White. Is it possible the 8000K tube glass is slightly neodymium doped? It has that slight blue iridescence that is typical of neodymium incandescent lamps.

Very nice comparison! Good job at finding the 8000K lamps, as well. It's very interesting how your camera has different settings for these types of bulbs.

Vintage products are the best! Nothing will ever compare to the quality of old, U.S. made fluorescent bulbs, ballasts, and fixtures.

My camera is a Canon D-60. It was a professional camera in its day, but has long since been superseded. It works very well for photographing lamps because you can control all the settings on the camera or run it in program, whatever you want. Usually I don't take the time to photograph lamps as well as I should!

The lamps were easy to find. Menards even has the lamps organized by color temperature, so I went to the end of the rack where the coolest lamps are and there they were!

They're crazy expensive or you'll have to buy a case. Ask BowlingMania14 if he'll hook you up or trade.
