• Streamlight ProPolymer 4AA Luxeon
  
  One for each car. Tough, waterproof, regulated, bright. Great beam and throw. Good for getting light into dark nooks and crannies in the engine bay or for lighting up distant street signs at night. A bit bright to use inside the car for close-up work, e.g. map reading.
• Streamlight ProPolymer 4AA 7LED.
  
  My general purpose house light. Tough, waterproof. Nice smooth, bright flood of light for close to medium range work inside the house. Beam has typical cool bluish tint of a light that uses 5mm LED's and won't reach out very far at all.
• PrincteonTec Matrix 2 headlamps 2AA
  
  One each for me and the wife. Luxeon, side emitting LED gives a nice bright beam that isn't too bright or too spot-like for close up work. Head and battery compartment are quite compact but has a full size head strap. Headlamps are probably the most useful but least used lights in our house. I'm trying to standardize on AA batteries and its not easy finding a headlamp that uses less than 3AA for compactness. High/low capability would've been nice, but hey, got these for only $15 each on sale at REI.
• UK 4AA eLED
  
  One each for me and the wife. Actually, this has become my main general purpose house light over the Streamlight 7LED. Its side emitting Luxeon LED generates a bright but not too bright beam that is sufficiently "floody" for close up use but still has some throw compared to multi-LED lights. It's not the flawless smooth flood of the Streamlight 7LED, but the color is very white and is...I guess "comforting" is the word I'm looking for, compared to the cool bluish light of the Streamlight. Very easy on the eyes.
  
  I agree with KenK and others that its mushy switch definitely feels different from the typical click-on/click-off switch, but it has never bothered me. It's just different. The 4AA eLED is an excellent, reliable general purpose light. For those accustomed to tactical lights, like Surefires, it's definitely not a "bright" flashlight but it makes up for it in efficiency and runtime. UK has replaced this model with the new two-stage Zoom model that puts out about 10 lumens more on high.
• Energizer ArcWhite 4AA
  
  A combo light--incandescent flashlight with a cold cathode flourescent lamp (CCFL). I bought this in some hardware store in Manhattan back in the 90's. I think it was the first flashlight I ever bought with emergency preparedness in mind. The flashlight function is OK with the incan bulb but the switch seems fragile and it doesn't always turn on with a single try anymore, especially if it's been sitting for a long time. It's not waterproof and I don't know if it would survive a drop onto concrete, so it's definitely not a "reliable" light like my UK's or Streamlights. The flourescent tube takes a minute to warm up, but boy, it really lights up a room for such a small CCFL, and for a long time. It even stands on its bezel at a slight upward angle for better illumination and the bezel is large enough to be a stable base, instead of the narrow tail end. In spite my affection for all of my newer LED flashlights, I hate to say it, but this old, not-totally-reliable incandescent/CCFL light might be my single most useful blackout light because I can just stick it on top of a bookshelf or refrigerator or the bathroom sink and it will light up the room very well with minimal glare even if you look directly at the light. I mean, I have used it in blackouts and it's very handy. As area lights, I think LED's are not really well suited to the task, so lights that aren't LED's aren't totally obsolete yet. It seems like you'll get more area light for the same power usage from a small CCFL like this light.
• Rock River 1.5W LED lantern 4AA
  
  Even so, I do have one LED lantern. Bright, regulated light. The light is rather harsh on the eyes to look at without jury rigging some sort of diffuser. I haven't gotten around to trying the Glad Press 'N Seal trick yet around the globe. The flourescent lamp in the ArcWhite will light up a bigger area better and is more useful, without the eyestrain, compared to the Rock River. This lamp has a bright strobe mode, though. If I ever had to call 911 at home, putting this lantern in strobe mode in the window will really draw attention to any responding units.
• Photon II
  
  My EDC light is an amber Photon II on my keyring that I've had for ages. Tiny but bright. Press to turn on, but also has a switch for longer use or to hold the light between the lips for handsfree use.
• Brunton Lamplight LED flashlight/lantern
  
  I also carry a Brunton LED in whatever bag I might carry. Single LED running on 3AAA that can either be a flashight, or by pulling the telescoping head, exposing the LED, turning it into a small lantern. Weighs next to nothing and will generate light for a long time. It uses a lens and throws a small, very defined spot with zero sidespill, which is usually a handicap for close up work. However, the lens does concentrate what little light the single LED generates for better medium range usefulness.
  

I'm thinking of getting a bit of a brighter EDC light to supplement the Photon. Something like a Fenix L0P or E1. I don't need a "tactical" light, although I wouldn't mind a Surefire as a gift. <img src="/images/graemlins/grin.gif" alt="" />

Oh, I gave my wife a Rock River 2AAA a couple years ago to keep in her purse. It has a surprisingly nice, bright beam for a cheap light and still turns on every time that I check it. My wife's not interested in flashlights, so if she loses it or lends it and doesn't get it back, this light is cheap and I won't mind.
