We are already seeing, handcranked led flashlights, In a couple of years we could easily have these in the form of desk lamps, and reading lights. All we need to do is find a way to have them glow with a softer light instead of blue.
Some of the high-end — I’m talking $250 per — LED flashlights are considered non-lethal weapons. No joke. Cops are actually trained in how to use those flashlights to temporarily blind a suspect.
Then they hit him on the head with the flashlight, but that’s another part of the training. I have a friend who’s a POST trainer, and ... well, never mind.
I have LED flashlights. One is charging in a wall socket in case the power goes out. Another is on my keychain. Another is in the center console of my car. And another is in the inside pocket of my favorite jacket. I like redundant backups, and I hate it when I can’t see,
The question is, when will I be able to buy an LED lamp that will screw into the socket of my home light fixtures? It’s a mature technology. We know it works. We know that it draws a tiny amount of power for the same amount of light relative to incandescent and even compact fluorescent bulbs. It’s environmentally responsible, cost-ffective, and long-lasting. So where the hell is it?
As far as the color goes, LEDs can emit any color. You can tweak the electronics, or you can just paint them. Spray dye on the diodes. seriously, that’s a non-issue. A few years ago, I threw a valentine’s day party where the whole house was lit in pink. How did I do that? I wrapped all the light shades in pink saran wrap (Brits call it “cling film”).
