<p>[QUOTE=&quot;Tallpaul000, post: 453729, member: 204&quot;]Im attaching a link to GE that gives spectral distribution verses radiant power for their lamps.&nbsp; </p><p><br /></p><p><a href="http://www.gelighting.com/na/business_lighting/education_resources/learn_about_light/distribution_curves.htm" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.gelighting.com/na/business_lighting/education_resources/learn_about_light/distribution_curves.htm" rel="nofollow">http://www.gelighting.com/na/business_lighting/education_resources/learn_about_light/distribution_curves.htm</a></p><p><br /></p><p>Incandescents are shifted to the red and weak toward the blue, but they do put out a continuous spectrum similar to the sun, while fluorescents put out more discete light in the red, blue green wavelengths of light.&nbsp; What Im trying to say is that you&#039;ll see colors differently using different light sources.&nbsp; Coin shows are the worst, because the are usually lit with fluorescent diffused light sources, also diffused light is not the best for picking up hairlines as the light is not directional, but scattered.&nbsp; </p><p><br /></p><p>I have an older friend who has overhead older cool white fluorescents.&nbsp; I showed him a beautiful toned Franklin half, but you couldnt see the colorful toning.&nbsp; I told him to turn off the overheads and turn on his desk incandescent, boy was he surprised.</p><p><br /></p><p>For my photographs, Ill use incandescent or halogen. However, I think I will buy some of the new fluorescents to see how they render the coin.</p><p><br /></p><p>Caveat, if your lights work, use them....[/QUOTE]</p><p><br /></p>
