I was trying to better understand LED bins and ran across this info
I’m not sure if the quote below is just the authors opinion, or if it’s industry standard.
“In terms of LEDs, the BBL is related to the correlated colour temperature (CCT) and is expressed in Kelvins (K). CCTs of 3000K are defined as warm white and lie towards the yellow region of the chromaticity diagram (Figure 4). Neutral white ranges between 3500 and 4000K and cool white ranges between 4500 and 5000K.”
What is NW is all relative to how your eyes are adapted. In the daytime with afternoon sunlight shining in my room, 4000k is warmish. At night time, when my eyes are adjusted to the 3000k ceiling fixtures, 4000k looks cold white, even with a little hint of blue sometimes.
Not sure what to make of this light. For AA/14500 lights I want them to be as small and pocketable as possible, as if I want any runtime I’d grab an 18650 light or larger. Seeing this as a low-volume light, almost a novelty, for people like me who have the large gt, the mini and want their little brother.
Smallest light? Smallest cell? This is an MBI Match Light, it has a magnet in the base, fits in a waterproof matchbook and comes in several colors. The light is turned on by push/pull on the emitter on top.
I wouldn’t mind the other way either… never fully understood “GigaThrower” (GT) as that actually signifies a billion candela (should hit Uranus with that one…)! Really it should be the MT or “MegaThrower.” Up next would be the “TeraThrower” with 1 trillion candela!
Cool trivia about that light. The battery is made with the push/pull activated switch built in. Those batteries can be bought online. Most of them available are Primary cells, but there is a rechargeable version too. MBI basically just added the LED. Since some very tiny, but bright, emitters are available in the world right now, it might be cool to see an updated version with a better emitter and a small optic. Maybe even a “tube” for the battery, so it can be changed out like a normal flashlight. It wouldn’t be as small, but it would be a bit more useful for most people.
