    SHOW SOME LOVE FOR INCANS ! ! !

    Purchased a Maglight AA Xenon today. First Incan I've purchased since about the age of 5. I compared it to a couple of my LED lights. All these lights are around 10 lumens or so. The LEDs looked good, reading a book, for example, was not a problem. However when I turned on the incan it was...

    What was the last LED light you purchased and why?

    This dark time of the year these light toys are more appealing. Here's my recently purchased Fenix E01, suspended. I diffused it with a piece of hockey tape - too much glare for reading much otherwise. Not a bad nightlight.

    Nichia GS LED observations

    Recently purchased a Fenix E01 with a Nichia GS LED. I compared it my Aeon flashlight, which has a top binned Cree LED. Both lights are ~10 lumens. The E01 (Nichia GS LED) has a blue/purple hotspot with a yellow flood periphery. The Aeon (Cree LED) sports a uniformly green tint. The Cree has...

    What was the last LED light you purchased and why?

    Fenix E01. Replaced Aeon as keychain light - smaller, brighter, similar runtime (30-40 hours). I muzzled and diffused the torch with hockey tape. Perfect!

    Digital vs traditional night vision

    I've been going berserk this morning trying to locate information about the digital night vision stuff, which is now cheap and easy to find, compared to the older 'analog' tube intensifiers. How does the digital stuff compare to traditional technology (Gen 1-3) without any IR light to assist...

    Incandescent: low lumens, long runtime ?

    Any available. I was thinking of 2-10 lumens, with a minimum runtime of 5-10 hours. Some sort of incan nightlight. For example the A2's bulb is good for ~50 lumens/1 hour. How about an incan bulb (hot wire) with an output of 5 lumens for 10 hours. Possible? Something about the quality of light...

    CREE 'truewhite' incandescent replacement LED

    GE & Cree have apparently collaborated to create a new LED replacement for the ubiquitous 60 watt incan bulb (links): http://www.tomsguide.com/us/ge-led-light-bulb,news-11725.html http://www.youtube.com/watch?v=A8Ucbqh6GhY&NR=1 http://www.truewhitelight.com/ I'm interested in the 'truewhite'...

    LED = Eye Damage?

    These LED lights produce a huge amount of blue light compared to more common light sources like incandescent lights and candles. The LED itself only produces blue light in a narrow band of the visible spectrum (apparently most damaging to the retina - see my above post). After passing through...

    LED = Eye Damage?

    It's possible. Apparently blue/violet light, at least in large amounts, is much more damaging to the retina than green or red light. Unfortunately the way these high efficiency white LEDs work is by converting a lot of ~450nm radiation (from the LED die) to white light (after passing through...

    LED candle/ warm tint 'mod'

    All sorts of things work. Just a matter of getting the tint you're looking for w/out too much overall attenuation. I definitely think blocking out a lot of the blue light was part of the effect I was after. Other than that, it's all in how you attach the filter. Rubber band works and is...

    LED candle/ warm tint 'mod'

    I still think candle light very pleasing. Very warm color (orange), which I like: Recently I decided to filter my cool white LEDs so they more approximated a warm light source. Not a diffuser nor a simple color filter, no.. I chose $5 sunglasses :) Don't laugh, this worked quite well. If...

    LEDs & 'Blue Glare' & Eye damage

    There seems to be increasing evidence that blue/violet frequencies of light cause much more damage to the retina than longer frequencies (green/red). See these two links: http://www.sunnexbiotech.com/therapist/main.htm http://www.sunnexbiotech.com/therapist/blue%20light%20and%20amd.html From...

    Scattering of light

    Re: Why are warm LEDs preferred by most on this forum? Rayleigh scattering and the 'Tyndall' effect ARE relevant. Read my above post. Anyway, enough drift on this topic I think :) Oh yeah, I like the neutral white LEDs. you're the troll as you've got nothing of substance to say. outta here

    Scattering of light

    Re: Why are warm LEDs preferred by most on this forum? My understanding is the Rayleigh scattering phenomenon which give the sky its blue color is caused primarily by the molecules which make up the atmosphere itself - oxygen, nitrogen, etc. I think we can agree these are much smaller than the...

    Scattering of light

    Re: Why are warm LEDs preferred by most on this forum? I disagree, Rayleigh scattering explains the phenomenon. A ray of light passing through a volume of space full of water droplets will spend much more time there bouncing back and forth between water droplets. In effect its length will be...
