Reddit mentions of Fortune BL-A7 Portable Black Light, 6.5" Length x 1.6" Width

Mine was like this but that LED one seems much better. I did illuminate a wide area in a dark interior bathroom, so a small diameter beam wouldn't be the same. But a wide beam like that looks great.

I settled on http://www.amazon.com/gp/product/B006T64ME4/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

Which one do you use? I use this one and it works pretty damn well for it's price.

Did not submit wishlist to ISFJ Mom-Santa early enough. Was informed that gifts for me were purchased a while ago, and it is too late... :)

Things that I really enjoy having that I would have enjoyed receiving as a gift, though (even if I got them for myself....):

• Bath overflow cover: If you're buying for someone who likes baths. Because baths are warm and awesome -- especially living in the relatively chilly midwest USA.
  
  
• Some kind of black light: Worked well as a gift when I was younger -- it would depend on the individual if they are older. It made for a long series of fun, "does this glow?" experiments -- and even now, I'll still sometimes trot it out to see if it glows.
  
  
• More expensive, but a device that gives you information on yourself -- such as sleep quality, activity level, etc. Don't have one myself, but would want want. The more independent it is from me doing stuff to it, the better. For instance, if it can actually detect when I am sleeping, that would be really cool -- even if it is sometimes a little off!
  
  I can't think of many other things that aren't even specific to what I like. I'm definitely trending after my (I think ENTP) Dad in the, "hard to shop for; if wanted a thing badly enough, probably got it for self a while ago instead of waiting arbitrarily for Christmas in order to tell someone to get it/hope someone gets it."

I think this was back in 2003. Even if they still made them I have no idea where to get them. There have to be more efficient versions by now. They were fluorescent tube UV lights powered by about a dozen AA batteries. About as long as my forearm, which is where I strapped them. I also put one on my bike which worked pretty well.
