Happy first day of Fall!
Yeh, yeh, I know. I’m not really that happy either, but only because winter is coming, not because Fall is here. I love Fall as a season because of the many birthdays and Halloween (my favourite holiday ever). And also it’s a time to regroup and get ready for the winter season. More importantly, it’s about making sure I have enough lighting.
If you’re lucky enough to be located in a more southerly part of the hemisphere where sunlight is still around for more than 8 hours a day, you might not be as concerned. But up here in the Great White North, we suffer from SAD (Seasonal Affective Disorder), which literally makes us sad due to the lack of vitamin D. It’s become so prevalent that there are vitamin D supplements in many foods available now. I’ve had to resort to the Tanning booth to get my zap of D.
And I’ve been reading up on the different types of bulbs available now and how energy efficient they are etc. Although I haven’t compiled all of my findings yet to do a good comprehensive post, I did however come across some interested trivia about lighting that I want to share…
Fact #1– Most infrared rays from the sun are blocked by ordinary window glass. A sunny room warms up because objects in the room absorb the sun’s visible light and convert it to infrared.
Fact #2 – Artists commonly prefer the light form windows facing the nearest pole (north light, in the northern hemisphere), since the light varies the least as the sun moves throughout the day.
Fact #3 – Thomas Edison tried many different substances to create a filament for his electric light, including cotton thread and the beard hairs of redheaded men, before settling on charred bamboo.
Fact #5 – In 1892, Nikola Tesla, hoping to improve on Edison’s incandescent lamp, accidentally invented a primitive laser instead.
Fact #6 – People are attracted to light: A 1974 study published in Lighting Design and Application by Taylor and Sucov found that when faced with two corridors, one lit more brightly than the other, subjects overwhelmingly chose the brighter one. No dah!
