New Desk Lamp

A week ago boingboing ran a short blarticle about this cool Kozo-lamps  (whatever is a Kozo lamp? The name of the designer? Wikipedia fails me here!) from Etsy, made from plumbing fixtures. I really, really liked the look, and decided to make my own.

So this evening after work I headed to the nearest Obi, and raided their plumbing department. One hour later and là voilá! my very own plumbing fixture lamp. Bask in it's galvanised glory!


 It is of course illuminiating the "New Annotated Dracula" (see review here) as is fitting, because, ah, vampires like plumbing. Yes.

From another angle:



 And finally a black-and-white close-up, in case you want to make your own:




 It is really quite simple, and did not take me more than an hour. Well, it is not quite finished, since I still have to stuff the two cables into a bit of shrink-wrap or so, but it does work. In case you want to copy my design, you'll need (please excuse me if I get the terminology wrong, my knowledge of plumber-terminology is sadly lacking. Clearly, I will never get to be a vampire.):

  • 5 "elbow" pieces for the legs and head
  • 5 T-pieces
  • 6 short male-male connectors, 4cm long
  • 1 male-male connector, 8 cm long 
  • 1 female-female connector
  • 1 longer male-male pipe
  • one 40 mm to 12 mm reduction (the head)
  • a 40 mm diameter (GU 4), 12V, 20 Watt halogen bulb
  • a 12 Volt transformer capable of delivering 20 Watt
  • a bit of wire
  • a bit of super glue (cyan acrylate) 
Everything together (except the transformer, since I had an 18 Watt trafo lying around - won't get full brightness with it, of course) cost me around 70 swiss francs, or 46 euros.

Assemble the lamp and don't forget to insert the wire into the tubes. solder the leads to the  bulb and insert it into the lamp-head - glue it in with a bit of super-glue. Don't use hot glue, since the head will get quite hot. Aaand... that's it. You are now the proud owner of a plumbing fixture lamp. Do keep an eye out for jealous vampires!

A few modifications could be made to the design: Using leds instead of halogen bulbs would decrease the energy consumption by about a factor of five, while keeping the temperature of the lamp-head down. I actually thought about doing that, but being a victim of the evil, evil instant-gratification  society that formed me, I wanted my lamp now, now, now!, and using halogen saved me at least 10 minutes of soldering. There might actually led-replacement lamps for the halogen standard GU 4 - I know this stuff exists for GU 5.3, since I use it for my bicycle lights. But the good old Obi didn't have them and... now, now, now!

 So, tell me what you think: Fugly? Awesome? Will you make your own?

  2. Male to male connectors are called nipples and female to female are couplings.

  3. Thanks! Now I am a bit closer to being a plumbing expert and thus prospective vampire material!

  4. I love it, but I already have like dozens of lamps (and a good supply of LED lamps), in case I can't help myself.

  5. I hear you - I am a bit of a light-junkie (especially in winter!), so I have quite a few of them myself. But this was so much fun to build that I am contemplating building a few more to give to friends and family ('cause they have to pretend to like it!) - maybe I can figure out a nice water-tap switch like the original designer...

  9. Love the lamp! I'm making my own, but running into some trouble.
    How did you screw the base together? Specifically the 5 Tees, 5 short male-male connectors (4cm long), 1 male-male connector (8cm long), and 1 female-female connector?

    Whenever I do it, and get to the last pipe, while I screw one end in the other end unscrews?

    Hopefully the solution is super simple and I'm just over looking it.

    Thanks in advance!

  10. Hey Anonymous,

    I ran into the exact same problem, and solved it by cheating: If you look closely at the photo, you'll see that there are two female conectors touching each other - they actually have no male connector between them.

    In the end, a rectangular base is not optimal - I built another lamp with a triangular base, wich is much easier to do! you can see it here

    Hope this helps,
    Boris

  11. Hey it looks cool but I came across this study thing which is eco friendly, eye soothing and has a battery back up of six hours also tested by one of the biggest eye specialist. Have a look :
