I intend to do something similar, Charles.  At the moment, I'm in a temporary location, but when if the lighting is similar when I get a permanent home, I expect to be getting myself a desklamp that will throw some warmer light on my work area.  My previous company actually supplied halogen desklamps for that purpose and one of the part-time student admins who works for me already brought in an incandescent light for this purpose.

Warm LED Light

I think this is a step in the right direction. Dimmable LED lights that are "warm" would be a great product for the home, much less cars. I have many dimmable lights in my home. Alas, all are incandescent. The dimmable LEDs available have a very narrow "dimming range."

Those white LED bulbs can cause eyestrain over long periods--they're just too harsh, although ideal for short periods of intense scrutiny when looking at fine detail.

Yes, choice is good, Ann. I have a cold white LED bulb in my office. About a year ago, I unscrewed it and replaced it with an incandescent.

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.

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.

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.

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.

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 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?
