<p>[QUOTE=&quot;desertgem, post: 489526, member: 15199&quot;]I vote with Kanga as certain light energy can activate free radicals on the surface . <b>Which</b>, if the other components~&nbsp; moisture, environmental substances, oxygen~ are readily available, toning or corrosion can occur. Ultraviolet light in such as &quot;black lamps&quot;, plant growth lights, SAD lights, or even the sun can contain varying amounts of UV.&nbsp; Dougs storage suggestion tends to eliminate the necessary factors. Heat can cause similar free radical reactions, so on a window sill you may get both ( depends on the UV transmission of the glass)</p><p><br /></p><p>Basically , if you can look at the light source, it is OK. The molecules in your retina react more than coin surfaces, so if there is no warning about looking directly at it, the bulb should be OK. That should be obvious about the sun.<img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie2" alt=";)" unselectable="on" unselectable="on" /></p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
