On Dec 15 ducksterman started a thread on "Fly Anglers Online' which ended up with a lot of good information on it . Someone suggested going to the Solux website (www.solux.com) for more information. If you do this and click on "spectrum" in the text and then on the first graph you will see that the Ott Light is not the closest match to the daylight spectrum. This may or may not matter.
The most important thing with regard to lighting is the intensity. The more light you have (within limits) the more the pupil of your eye will constrict and the sharper the image will be and the greater the depth of field will be (just like in camera). After this the spectrum does play an important role and it does play an important role in matching colors. Perhaps some of the difference of opinion over which light is better is based on who has the lamp with this most output. This cannot be determined by the wattage. There are also many lamps available off-the-shelf which over "full spectrum" lighting".
