    Especially for reading, unlike some people I guess. My CFL reading bulbs are rated 5700K or something, on the blue end. And their lumen output is similar to a 200W incandescent.

    The LED canister we installed in our kitchen over the sink is extremely bright and "cold" and I love it that way, though I'm glad it's dimmable for when I don't need to see the microbes.

    I don't have an LED reading bulb yet, but I am certain they are out there. Keep hunting?

      high temp (cool blue) is my favorite.  

      It's actually interesting making my own LED bulb.  I should have time to finish it after Christmas, and if it works I'll probably outfit my kitchen with LED track lighting.  Anyhow, there's no limit to how bright I can go, it comes down to how much light I need.  Even at insane lumen outputs, the LED "bulb" I'm making would use less power than a reading incadescent bulb.

      I'm also building my own LED flashlight for home defense.  Flash it in someone's face, and it will blind them momentarily, giving my time to whack 'em with it.  I don't really need anything for home defense, but I like the idea of a flashlight bright enough to blind people.  :)

        especially if they weaponize their emergency lighting!

        My home defense plan is let them take whatever they want. I am worried they won't get much cash out of my 1989 radio tuner or any of the other outmoded electronics. They can have my opera CD's those may be worth something...

        Actually around here if things get stolen it's usually big equipment, like front-end loaders, you know, useful stuff. When we first moved here I used to get very puzzled at news reports describing major parts from state-owned road equipment that were stolen during the night. It seems to me thieves here at least have a good work ethic and a do-it-yourself attitude.

        I'm also impressed when I hear about thieves who have pulled copper pipes out of an abandoned home. That at least shows initiative. Must be pretty hard work for sort of a medium payoff.

        •  My primary home defense is a dog (1+ / 0-)

          but if the intruder actually knew my dog he would laugh and go right on with whatever he's doing.  My dog is a rescue puppy who hides behind me whenever strangers appear.  She does have a pretty good bark, though.

          That's the main problem with an LED flashlight: I can't use it around my dog because it could damage her eyesight.  With incadescent lights, they turn on slowly enough for eyelids to snap shut in time to protect the retina.  An LED lights up instantly, giving the eye no time to take protective measures.  I accidentally glanced at the LED when I tested it and ended up with a spot in my vision for a few hours.  I go out at night with my dog, I might have to get her shaded goggles or something, lol.

          •  Your dog sounds very nice (0+ / 0-)

            From a business standpoint, I think thieves are likely to pass by a place if there's a barking dog, just because it's more hassle and potentially dangerous. They'll do the easier places first...have to consider your hourly rate to be a profitable thief.

            That's interesting about the LED flashlight being hazardous for eyesight. I wonder if most people know this? Maybe you could do a diary about this, or post in the Pootie/Woozle diaries.
            I think it would make sense to keep a non-LED flashlight for dogwalking...different generations of tech for different purposes. Like why I need my older computers around, my old modems, etc...you never know, LOL!

            Anyway, I wonder if a screen or filter over the LED's would prevent the hazard but still leave the flashlight bright enough to be useful? Like maybe even a strip of the window-filtering stuff. Easy to tape in place, might work?
