I'm looking for information on the psychological and physiological effects on humans of exposure to different colored light or an environment lit only by a single light color. There's a plethora of (poorly sourced) information about things like "color therapy" and (unsubstantiated) claims that "red light makes you angry" but virtually nothing that's backed up by any actual research or explanations of how it works.
The house I have has a motion detection floodlight installed (http://amzn.to/1KyAd5N). Unfortunately, the original installation was a bit too high, so most of this floodlight is shadowed by the roof eave. I would like to lower it by about 6 inches. I don't want to change the original circular mount that's in the wall. Is there such a thing as an adapter/pipe that I can install connect to the original circular mount that I can then reattach the floodlight too? (Kind of like a periscope) I'd welcome other solutions - but I'm not very handy.
Directors of photography like Roger Deakins, Robert Elswit, and Robert Richardson have distinct styles but are nevertheless first class examples of cinematography done right. I am looking for resources that delve into the type of lights they use, lighting plans (specific setups from certain scenes), and examples of intensities of the used lights (in LM). Any of these would be helpful really.
I have a new apartment. There are lovely big windows, but there aren't any curtains - and the rod is so flimsy that it likely can only support the lightest of linens. Unfortunately, there is a big orange streetlight directly outside, and that leads to sleepless nights. What color and material of curtain might mitigate this issue? [more inside]
A light somewhere on my PC motherboard, my best guess is near the Ethernet connector, has recently begun to flash irregularly even after system shutdown, which is driving me nuts, because I sleep in the same room. I can't easily cover up the light or open my case, and since the PC was built for me by someone I can no longer reach, I need your help to kill that light. [more inside]

I do a lot of online video conferencing from a home office. I’m looking for desktop light fixtures that create a video image that makes me appear to be a good guy, as opposed to someone you want to avoid at all costs. The lighting is good during daytime hours, but at night I look creepy. I need to find lights that provide even, gentle, and warm illumination. [more inside]

I own a wine rack that holds 13 bottles, which is quite a supply for a single guy, so bottles end up on the rack for a few months. It's as much an art piece as it is a place to store the bottles, but the wine is strictly for consumption. In other words, none of the wine is valuable. I only buy 'em to drink 'em. How long can wine sit in a wine rack at room temperature in a well lit room before the wine starts to go bad? [more inside]

I've read and been confused by many other AskMe's about this, so here is all I want to know: What bulb can I go out and get at Home Depot or Lowes, for under $20, that is a full-spectrum fluorescent that will fit into your standard ~24" housing? This is for a bird kept inside. [more inside]
My six-year-old son asked me a question I'm stumped by (one of many). He asked "Why are there different colors?" I half-attempted an explanation about light wavelengths and light reflecting off surfaces and soon realized I was a) over his head and b) over my own head. How would you explain the concept of color--of what color really is--to a six-year-old? Obviously very simple language is needed here.

Is there such a thing as too much light in a living space? I'm looking for a new apartment. One possibility is a large studio in a high rise tower (30th floor) with floor-to-ceiling west-facing, unobstructed windows. This is in the Northeastern section of the US (an area known for hot and humid summers). The property developers have not included cellular shades, only standard mini blinds. It is lovely now in the winter and makes the apartment seem large and cheerful, but will I regret signing a lease come July?

Our office building is in the process of switching over to all-LED lighting. Our recessed can lights were recently swapped and it's causing a lot of grief- will we just get used to it over time or can I buy some warming filters that won't melt or look like yellow/orange/red dots all over our ceiling? I have only found theatrical lighting sources online so far. Help!
Three of the hardier herbs we had been growing in our back yard--sage, mint, and lavender--survived our absent-minded neglect and made it through the summer. As the temperatures drop, we've taken them indoors for the winter. We can provide either 1) warmth and artificial light, or 2) cold protection from the elements, but natural light all day long. What's better? [more inside]
I replaced a ceiling light in a 1950's-wired apartment. There are insulated black and neutral wires, but no ground connection (fixture has ground wire but just connected it to mounting bar).

Clueless new homeowners here. After a shower and a use of the toilet upstairs, water started dripping through a screw on the track lighting in the kitchen. It started maybe 10 minutes afterwards and lasted maybe 10 minutes, maybe a cup or so of water total, then stopped. What happened? What do we do now? Call a plumber, presumably, but how urgent? An electrician too? Is there danger because of the light fixture? [more inside]
You are not my electrician but I was wondering if you might experienced this problem. My bathroom has a fluorescent light with a pull switch and a ventilation fan that comes on automatically. I think they run off the same circuit. The light normally comes on fine but after a while- probably about half an hour normally- the light goes off. [more inside]

I'm having problems with taking photos indoors when there's a lot of movement. Prime example: weddings. Most of the shots turn out blurry. I have a basic digital camera with a setting for low light but it's at a low resolution and too grainy to print. Without using a tripod or flash what's the best way to adjust the manual settings to compensate?

I came across this article and became concerned about my eye health, in light of a new LED monitor that I recently bought and use for about four hours each day at home (at work, I look at an older LCD monitor with a CCFL backlight for eight hours). Is this something to be concerned about? Also, can some sort of (UV) filter be placed in front of the screen to reduce risks? Currently, I have my LED monitor set to 0% brightness and 25% contrast.
Season 4 of Game of Thrones was brutal, full of death and gore. Now we're watching Penny Dreadful, True Blood, Fargo and catching up on Hannibal, Dexter and Vikings. All of this is enjoyable, but the violence and gore has become a bit rote and unnerving. Recommend some lighter tv stuff, please. Examples of what we've liked and disliked below the cut.

I spend a good deal of time video-conferencing via Skype.

Just purchased a ceiling fan that allows for 2 60W lightbulbs with a candelabra base in a closed glass dome. Need something brighter as this will be the only light source in the room. Having trouble finding small CFLs or LEDs with a candelabra base in 18W (equivalent 75W incandescent) or higher that will fit in the dome. Any ideas on where to find these kind of bulbs, or if they even exist? If not, any other ideas on how to keep the fan and to safely add some wattage? [more inside]
I have to stare at this thing an awful lot for work, and of course I stare at it recreationally too. But after a few hours a horrible dazed feeling creeps up on me.

we have a three way floor lamp (you know, the one that goes low, medium, high as far as light intensity, and requires the special bulb) in our bedroom. recently, the switch seems to have gone wonky, and only offers low, and, if we twist the knob only a certain amount, high. while we've learned the trick to make it work, and it's not like it's hard, i'm starting to get pretty annoyed with the fact that this isn't working anymore. it was not a crazy expensive lamp, but it also was not cheap, and i like that lamp, and i don't want a different one. i assume the problem is in the socket itself. can someone who hasn't tinkered with electronics since she was a teenager (and that was mostly to take stuff apart to see how it worked) but worked as a mac tech as an adult change out the socket pretty easily, or is this something i need to leave to the professionals?
I have a candelabra chandelier (E12) and I want to use LED bulbs in them. The problem is, the bases of the bulbs are so wide that they bottom out in the socket before the bulb's end pin can make contact with the bottom of the socket. The socket does not have a tab I can pull out, and the chandelier is made in a way that replacing the sockets does not seem very accessible. I have encountered this with two different brands of light bulbs, and looking around, it seems that it is a common problem with LED lights. So, I want to stretch out my light bulbs. [more inside]

I have a 150 watt ceramic infrared heat bulb similar to this one http://www.amazon.com/Zoo-Med-ReptiCare-Ceramic-Infrared/dp/B0002AQCPK that I use next to my desk to help keep me warm. It produces no visible light, only heat. Sometimes I have the urge to stare at it, can it hurt my eyes from the infrared radiation, similar to how looking at a regular light bulb can hurt your eyes? I am also interested in how these bulbs work, and the type of infrared radiation they give off if someone can explain it to me.
I've always packed light by taking a backpack on all trips and going carry-on only. But I'm going to be extensive international travel with a 35-liter backpack and want to know how to pack even lighter. Usually I only go on 1-week trips, and thus pack a shirt for every day, etc. How can I pack lighter? I've heard that Merino wool is a good material for shirts that can be worn a couple times before needing a wash. What are your tips and tricks?
