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.
Eric Doster of iFixit talks about the most surprising aspect of the Microsoft Surface Pro 3 teardown. In a presentation at Medical Design & Manufacturing Midwest, iFixit gave the Surface Pro 3 a score of one (out of a possible 10) for repairability.
Time was when a talented driver with a manual transmission could beat any car with an automatic transmission in a straight-line race. No more, though. In tests at GM’s Milford Proving Grounds near Detroit, the 2015 Chevy Corvette Z06 equipped with an automatic has turned 0-60 mph times of 2.95 seconds, making it about a quarter of a second faster than the same vehicle with a manual trans.
If there’s a microcontroller-based Web server in your future, then you’ll want to take note of an upcoming Design News Continuing Education Center class, "How to Build An Embedded Web Server: An Embedded TCP/IP Tutorial.”
