That's a really clever technique. I worked with a pinball company (OK, there's really only ONE pinball company), and their solution was to mix additional colors in with the white LEDs to make them look a little less ghostly. Reflectors were also used to warm the white LEDs up a little bit. As you can imagine there are quite a few bulbs in a pinball machine and finding a solution was really important.
White LEDs did make great replacement for flashers, which was really a 12V bulb hit with 24V, as you can imagine, they wear out pretty fast.
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.
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."
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 question of whether engineers could have foreseen the shortcut maintenance procedures that led to the crash of American Airlines Flight 191 in 1979 will probably linger for as long as there is an engineering profession.
More than 35 years later, the post-mortem on one of the country’s worst engineering disasters appears to be simple. A contractor asked for a change in an original design. The change was approved by engineers, later resulting in a mammoth structural collapse that killed 114 people and injured 216 more.
If you’re an embedded systems engineer whose analog capabilities are getting a little bit rusty, then you’ll want to take note of an upcoming Design News Continuing Education Center class, “Analog Design for the Digital World,” running Monday, Nov. 17 through Friday, Nov. 21.
