Incandescence Any object that emits visible <span class="highlight">light</span> because it is heated to a high temperature is incandescent. Examples of this are candles and any form of fire. Even objects that we don’t normally view as a <span class="highlight">light</span> <span class="highlight">source</span> are incandescent if they produce <span class="highlight">light</span>. A stove element or the element inside of a toaster are good examples of this. Bioluminescence Fireflies sparking <span class="highlight">on</span> a summer's evening. Jellyfish glowing <span class="highlight">in</span> night waters. These are examples of bioluminescence - <span class="highlight">light</span> emitted by living organisms

Page 12 5.1.1 Indirect Lighting Indirect lighting uses fluorescent or metal halide lamps to up light a light color ceiling; the resulting reflected light is inherently very soft, shadow-free, and low-glare. Indirect lighting works well for both paper-based and computer tasks in rooms where the ceiling height is at least 9'-6" and preferably more than 10'-0". 5.1.2 Direct Lighting Direct lighting uses down lights to illuminate the reading tables. The down lights can be as small

Page 5 lamps have a bluish-white color; some librarians prefer this color, especially <span class="highlight">in</span> desert climates, where the cool color of <span class="highlight">light</span> may psychologically imply a cool relief from the hot exterior environment. It should be noted that the choice of lamp color has no effect <span class="highlight">on</span> <span class="highlight">light</span> levels or cost - it is basically an aesthetic choice. Regardless of which color is selected, the <span class="highlight">light</span> spectrum from standard fluorescent lamps provides adequate color <span class="highlight">rendering</span> for the visual tasks <span class="highlight">in</span>

Page 10 Some designers try to combine the parallel and perpendicular schemes into a diagonal arrangement of rows, but this offers no <span class="highlight">real</span> advantages and creates a visually distracting layout that is hard to coordinate with the ceiling structure. 4.2.3 Indirect Scheme The indirect scheme uses up lights <span class="highlight">on</span> top of the stacks or suspended from the ceiling. All of the <span class="highlight">light</span> is reflected off the ceiling, so the illumination <span class="highlight">on</span> the stacks is very <span class="highlight">soft</span>, and the entire range of stacks appears
