Now, did you buy one of these or not? It's impossible to have a sensible discussion without knowing. If you didn't buy a TrueColor lamp, there's no mystert about your odd results. It's really tough to find out from anything that is in my package or anything on the cards that the new bulbs come on, what the color balance is. So what is the Ott web site? I was operating on the Staples web site. But I bought it at a store. http://www.ottlite.com/ shows the products. Some of them are "TrueColor", some aren't. See which is your product. When I got home, however, and looked at my prints compared to my monitor, they looked greenish. So I suspected the color balance of the Ott light was not daylight, and I wondered how I might check that. I don't own a color spectrometer of some sort, but I so own a digital camera. So I am trying to think up a method of using the camera to measure the white balance of the light. Forget it. It can't be done. Fluourscent tubes do not have a continuous spectrum. Then why are you advising me on the True Color Ott lights? Because, with care, it's possible to approximate a continuous spectrum. That's what the "TrueColor" tubes do. But you can't measure the colour temperature of something that is not known to be a continuous spectrum. I suspect you're simply bought the wrong product. Andrew. |
