I have light-sensitive eyes, too, as well as light spectrum sensitive. I wear dark glasses in sunlight and sometimes on cloudy days, too. Whether there's a connection between those hadn't occurred to me. Interesting question.
The wonderful thing is that we live in a free country and we don't have to be all the same. Of course some stores that I have seen would not give that impresion. Why should I have only one choice, that of "warm white" light? Is nobody brave enough to offere a product other than what marketing has decided is what the masses will be offered?
William K, I agree. I was always curious about the number of customers wanting warm color lighting versus the cool look while developing LED light kits for Hunter Fans. I personally like white light while working in the lab and at my desk. White light makes desktop and wall surfaces brighter for seeing small color bands on resistors and IC part numbers. Here's a video of the NXP demo presented at this years CES conference. http://www.youtube.com/watch?v=bRieORS6g1w&feature=youtu.be
The "you tube" light demonstration was interesting, and it looks like they have done well in emulating an incandescent light bulb. They are half way there. Now all that is needed is a means to control the whiteness of the light independantly of the intensity. Perhaps they never thought about that option.
Of course, by emulating the light bulb they did avoid having to add more wires. I am probably one of the very few who would be quite willing to revise my wiring to support more flexible colors of lighting. Of course, being qualified, willing, and able is a rare thing in this day and age.
Unfortunately, William K. you are only partially correct. This wouldn't even be such an important discussion if we were allowed to choose the lighting type we wanted based on color, preference, costing, efficiency or whatever is most important to the individual. However, the free market was stepped on with others telling us what those priorities should be...and which "better mousetrap" we HAVE to buy.
Jack, it seems that you are correct. I forgot about our legislative body's decisions that were made based on all of those emotions. They seldom let reason and intellect interfere with their process, and so now we are stuch with that pale orange glow lighting.
Forgive me, I was thinking rationally. I hope that the lighting police are not on their way just yet.
It's not just the old-fashioned fluorescent bulbs that have that awful greenish glow but also the CFLs--those were the ones I was referring to. I agree with William K--there should be variety and choice, not only for different people, but for different uses. The cold white light of LEDs is great for seeing fine details.
The Chicago Auto Show has long been a haven for truck introductions, and this year’s edition was no exception. Chevrolet, Nissan, and Toyota all showed off new trucks, while competitors rolled out concept cars and production vehicles.
A tiny new MEMS-based reed switch may enable engineers to reduce the size of the electronic circuitry in devices ranging from ingestible endoscopes and hearing aids to insulin delivery systems and brake fluid monitors.
Visitors to this year's Pacific Design & Manufacturing Show will have an opportunity to boost their electronics acumen, thanks to a series of Learning Labs covering topics ranging from medical sensors to smart packaging.
