Business News Update: Sunlan Lighting
Sunlan Lighting is not your Grandmothers or even your Mothers Lighting store. Grandmother used standard incandescent bulbs. Many industrial companies used 500-, 750-, 1000-, and 1500-watt bulbs in the warehouses. Schools and stores used 250-to-500-watt bulbs in fixtures. There were three-way 100/200/300 -watt bulbs. All these bulbs looked like a standard 60 -watt bulb, except they were much larger. Most homes used 25-40-60-75 or 100 watt bulbs in fixtures.
In the 50s, many schools and stores Your Mother visited used long fluorescents. As the development of fluorescent lamps continued, new sizes, shapes, and colors were created. The colors were developed to appear like different times of the day. The Kelvins, the numerical names of colors, were given identity names used constantly industry wide. Warm white was 3000Kelvin, Cool White - 4100 Kelvin and Day Light - 6500 Kelvin. Most of the lamps had a Color Rendering Index -CRI- between 60 to 70% of natural Sunshine.
When Compact Fluorescents were developed, the lamps were able to be installed in common fixtures. Specialty lamps were developed for fixtures that could only be used by one lamp. The light quality was improved to a CRI of 80.
A very few fluorescents were made with special Kelvins including cool green for computer work, plant lights at 7500 Kelvin, and 55 to 59 Kelvin to create a high CRI of 90.
Many people complained of headaches under these lamps and of looking greenish. Today, they are considered a bio-hazard and no longer being manufactured.
