I recently bought an xte q5 7b tint just for my bedside flashlight
I’m just wondering if anyone actually buy it just to feel nostalgic about the incan colors or do they have a proper reason for that?
I mean if night vision is required a red LED would be much better but why yellow?
comparing to a 3D incan maglite
incan, xte q5 7b, nichia 219b, xml2 u2 4c
incan, xte q5 7b, nichia 219b, xml2 u2 4c, xml2 u2 1a
I’m surprised that this 7B tint is cooler than a generic 1mm LED
so… why yellow? I’m just wondering what are your reasons for an extra warm yellow tint
I think the “purpose” is the higher CRI of the warmer tints. Most >90 CRI LEDs from Cree are in the very warm tint range. Also for general purpose home lighting the “cozy” feeling of warmer tints is more appealing to human beings - at least to me.
Natural outdoor light has different colours depending on the time of day (and the weather and pollution level). When the sun is low in the morning or evening the light has to pass through a lot of atmosphere and more of the short wavelengths will scatter and disperse. And longer wavelengths will punch through. This is why the sky is blue (shorter wavelengths) and the sun is yellow and the sunset/sunrise is orange or even red (longer wavelengths). Typically the cool night will make the atmosphere clearer in the morning, water condense out at night and fall as rain and wash away the particles that scattered the light in the evening. So the light in mornings often is less yellow/red than the light in the evening.
Also an open fire at night, or a candle at your dinner table, will give off a yellow or red light.
Your brain instinctively reacts to these different colours of light. So you typically relax from warm yellow light and get ready to go to bed. And bright white light will make you more alert and active. This is programmed into your brain by the evolution.
You can use this knowledge to make work environments more productive (blue-white light) and a bedroom more relaxing/cozy in the evening (yellow/red light). You can also use this to help you wake up in the morning, using a lot of cool-white light in the bedroom. Or just pull the blinds and let daylight in...
Also the warmer/redder light seems to punch through rain and mist better.
I have some 7A flashlights. I use them as lanterns during evening outdoor grill parties. Along with candles and kerosene pressure lamps.
Warm white tints IMO don’t look anything like incan. Even your photo’s show this, with the incan arguably looking closer to the the Nichia than the WW.
I also prefer warmer tints, they produce more contrast. Take a cool white and a warm white (or high CRI) light outside at night and shine them on a tree at 100-200 meters, it’ll be easier to make out the individual branches and leaves with the warm white (or high CRI) emitter.
I had read some where quite a while back that the warmer tints were helpful to Firefighter’s, ER and flight deck personal, (night launches) military, ect, where fire and smoke would be a concern. I think it was Surefire? I have a few high CRI lights around the house, and I carry one when hunting, which most of the time is in crummy weather, they do make a big difference.
7B is not extreme tint. I have 8D4 (2700k) and its pure awesomeness. Much more comfortable to the eyes with much better contrast, just like incandescent indoor lights are the best. I know not everyone like them and prefer cooler light to stay awake in the night.
I also enjoy neutral tint but I HATE the so-called cool white tint. More blue than ‘’cool’’.
Green, Purple and Blue are called cool colors, while Yellow, Orange and Red are called warm colors. This is quite normal in visual arts for example, where that is like the "default" way to refer to colors.
Yes but technically it is wrong, in science blue are the warmest color (purple is the most extreme) and red are the coolest. Just because from our weltanschauung based from nature, fire is red and ice is blue.
