Full-Spectrum Light (issue 46)

Around the world different people are talking about how they use full-spectrum lighting in their day-to-day lives. We feature some of the best here.


Sunday Salon – Autumn and Winter
I love this time of year and also dread the days when the cloud cover is so dense it feels like we are under a deep gray blanket. When the gray get to be too much, I drape strings of white lights around the house, put full spectrum light bulbs in my lamps, and light candles. All this reminds me that the sun will be back.


Plants for Low-Tech Tanks
What follows is a list of some of my favorite plants. All of them are easy to keep and grow in a low-tech planted tank. All you need are a good substrate that is made of either a mix of dirt and sand covered by a layer of fine gravel or one of the many commercial planted tank substrates, approximately 1.5 watts per gallon of full-spectrum lighting (a double-bulb fixture will do for most tanks)


Red Rainbowfish
This fish looks good under any aquarium bulb but especially under bulbs that have a peak in the red part of the spectrum that really highlights red fish. The fish look more red and less orange. You may want to consider using such a bulb to bring out the best colors in your fish. In heavily planted tanks, some hobbyists use full-spectrum lights at the back for the plants but use a red bulb at the front to accentuate the fish.


Ayurvedic state of mind
Get some sunshine and fresh air daily. Use full spectrum light bulbs in the darker winter months.


How to Prevent & Heal Osteoporosis
I try to be out in the sun for 20 minutes each day. In one hour, light skin produces 23 IU of vitamin D per square centimeter, and dark skin 10 IU. We have 20 sq. feet of skin or 18,600 sq.centimeters. If you expose 30% of your body (5,600 sq.cm) to sunlight or full spectrum light for 20 minutes, then you’ll make 18,600 IU (dark skin) to 43,000 IU (light skin) of vitamin D. That’s easily within the 2,400 IU we need.


The Healing Path
For depression, I make a tincture called Blissful Spirit. It utilizes St. Johnswort and Mimosa to relieve symptoms of depression, anxiety and panic disorder. You may want to consider replacing any fluorescent bulbs in your home to full spectrum bulbs.


Tea and Feathers
Combine their sociable natures with the fact that I have a daylight bulb in the lamp next to me for knitting purposes (Birds can see ultraviolet light – they have a rather expensive full-spectrum avian bulb near their cage – and clearly enjoy natural light. They’ll sunbathe if the light’s streaming in from outside, but it’s October and the light is weak and watery outside.)


Chimpanzee (Pan troglodytes) Care Manual
Lighting levels should be approached in the same manner as temperature, with a gradient of light intensity and spectrum available throughout the enclosure. Some areas should have full-spectrum light conditions, and chimpanzees should have the opportunity to select those areas if they desire. Skylights in indoor enclosures can provide natural sunlight during the day, but may or may not allow true, full-spectrum light to penetrate to the exhibit (i.e., glass can prevent/absorb UV light). Natural spectrum bulbs (preferred) or fluorescent bulbs are required when animals do not have access to natural sunlight for extended periods(greater than one week).
