The Lair

The bugs here on the east coast will fly into an open flame! I have an orange led in the fixture by the back door. Every year I have to open it up and empty the bugs out. All any kind of light here does is allow the bigger bugs and frogs to see and eat the little bugs.

 

That too. My interior lights are red and it's true. It's definitely better than white light, at least for me. I figure worst case, I'll just get some red acrylic and add it as needed when the time comes.

 

My patio light is white LED and we never have bugs.

 

Then I'm moving to Central Ohio!

 

Fvck no! Don't do that! We charge people for lobster here and have shitty weather!

 

But not any bugs apparently. The state bird of Pennsylvania is the mosquito, and I am only 3 miles from the line.

 

Scientifically speaking, Cyan (aka blue-green) is the best color for functional dark adapted vision. I'll spare you the rest of the scientific mumbo-jumbo about rods and cones, rhodopsin, and G-protein coupled receptors. It's enough to get you through a round of Jeopardy!



Hence the reason Navy CIC's are always blue:

 

While this might be true now (Military Applications), there is still some controversy over the subject and it wasn't always the case:

"A red light has been the traditional choice for retaining your night vision since before WWII when the military settled on red as the best choice. Recently, there has been a move to green and blue-green light, precipitated in large part by the military's change to green, which itself has been primarily motivated by the increased use of night vision equipment. As it turns out, green light also offers some advantages over red as a means to retain night vision capability. However, it isn't cut and dried.

Total brightness, or illumination level, of the light has a potentially more significant effect on night vision retention than does the choice of red or green. Because your eyes are more receptive to green light, we gain better visual acuity at lower light levels than when using red light. Green also allows for differentiation between colors that red does not and the magenta used on aviation charts, for example, is readily readable under green light, not always the case with red.

Both reasons contribute to the fact that pilots and many others generally seem to prefer green over red, it simply makes it easier to see and read in the dark cockpit. The potential problem is with the actual illumination levels we use, not the color of the light. The brighter the light, the more negative impact on night vision, both in our capacity to see and in how long it takes to gain back optimum night vision. This is true regardless of whether it is red or green.

Ideally, you want to use only as bright a light, red or green, as is necessary to perform your chores and no more. However, if you have a brighter light than you actually need, a brighter green light will generally have a more negative effect than an equally bright red light. Green or blue-green has a greater capacity to adversely effect night vision because the eye is about 100 times more sensitive to these colors, so even moderately too bright light can have a serious deleterious effect.

Another complication is that individuals' visual acuity at low light levels varies quite a bit, so what would be perfect for one, might be too bright or too dim for another. In other words, without some means to vary intensity, odds are no light will be perfect. Bottom line is that red or green will both perform adequately, but what you really should be more concerned about is to avoid very high illumination levels, of either color, if retaining night vision acuity is your goal."

 

Also it would be embarrassing to some to have a pink submarine.

 

Also did everybody miss the 75th anniversary of the beginning of the Battle of the Bulge?

 

Although, I did just attend our department lunch out of house with three highlighter pens in my breast pocket that represent the various stages of QA/QC here.

 

Nope, I recorded it on my Tivo so I can add the middle and end, then watch all 15 hours of it at once.

 

That's not very Lair worthy...

 

What is these days Rahl? What is..........

 

​

I would ask @EatSleepTacos, but he isn't Captain any more, so...

 

Exactly!

I bet if we chatted him up on Hangouts he would know.

 

I do use Hangouts quite a bit, but not to talk to Randall.

 

Well I bought something for the truck last night but now I don’t know if I’ll share in here since I smell a mutiny lingering about.

 

It's truck nuts.
