I’m getting older, losing my near sight, and the world is growing dim. Sounds dire. And while it may be true, I think a big part of my problem is the light bulbs in my shop. Unlike most of you, I have a photographic record of the lighting in my shop. I recently compared photos I just took with photos I took several years ago. There was a noticeable difference. My shop is lit with long lasting compact fluorescent light bulbs. These things may last a long time, but their performance degrades significantly over the course of a year or 2. You can see this by installing a new bulb next to an old one. Light bulbs have 3 characteristics we need to know about:
Color temperature, expressed in a temperature in degrees K , is the color of the light. Generally, incandescent bulbs are yellower (we call them warmer). Fluorescents are bluer (colder). The color of the light isn’t a huge issue for us.
