Cheap, easily obtainable full-spectrum fluorescent bulb

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]

Why are there colors? Explain like I'm six.

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.

Let There be Light?

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?

How can I warm up the LED can light tone in my office?

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!

Tips for wintering my herbs indoors?

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]

DIY: Old ceiling light, no ground -- what's the worst that can happen?

Brief water leak through ceiling track lighting-- what now?

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]

Bathroom light turning off

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]

How to take better photographs of movement in low light indoors.

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?

Do LED lights cause permanent eye damage?

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.

Recommend some non-violent TV

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.

How can I subdue the harsh glare from sunlight?

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

help me fix my three way… lamp.

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?

Can I stretch out my light bulb?

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]

How do ceramic infared heat bulbs work and are they safe to stare at?

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.

Packing light

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?

How to Get More Light?

I recently moved into a new apartment on short notice. One thing I didn't realize when kicking the tires was that there is no natural light in my bedroom during the morning. This tends to make waking up an unpleasant and lengthy event—it's dark, and often I just fall asleep again. I don't want this to happen, and I've noticed that when I sleep in a room with good morning light exposure I wake up earlier and happier. So: how can I replicate a rising sun in my room? Full spectrum light (like for SAD) hooked up to a dimmer hooked up to a timer? Clever arrangements of mirrors?

Has anyone heard of spontaneous remission for severe bouts of depression

I've struggled with depression for 30 years and have tried multiple medications/treatments, light therapy, Transcendental Meditation, etc. The last modality I had so much hope for was Transcranial Magnetic Stimulation; the treatments actually made my depression worse. Since we all know of cases where tumorous cancers have disappeared without explanation, I'm hoping someone has witnessed this occurring in a friend or loved one who's been diagnosed with clinical depression?
