A floor lamp with 4 spots


Material :
  • 2 tubes MRB : 1000 mm. (reference 13 = 17,9 x 20,4 mm)
  • 4 tubes MRB : 400 mm. (reference 13)
  • 4 tubes MRB : 100 mm. (reference 16 = 20 x 22,5 mm)
  • 4 tubes MRB : 100 mm. (reference 21 = 25,3 x 28,3 mm)
  • 4 tubes MRB : 40 mm. (reference 21)
  • 5 sleeves. (reference 13)
  • 5 stoppers. (reference 13)
  • 4 elbows : 1/4 small ray female-female (3/8 inch)
  • 8 screws Allen without head : 8 x 30 mm.
  • 8 nuts : 8 mm.
  • 8 wing nuts : 8 mm.
  • 4 screw lamp holder : E27 with 17 mm hole.
  • 100 mm Paris tube : 17 mm diameter.
  • 4 electric extensions : 5 meter. (2 x 1 mm² flat cable)
  • 4 color spots.

    Some advice :
  • The difficulty of this assembly lies in the fact that you need to do a few hard-solderings, and everybody hasn't got a blow lamp.
  • If you find a colleague who can do for you the solderings, then there's nothing left but do-it-yourself.
  • Prepare all you tubes which are already drilled and filed, so that they can fit perfectly together : this is the case for the T-pieces.
  • The 8 nuts (8 mm) will be fixed using a big 8 mm screw, while you're soldering. (screwtapping again may be necessary)
  • The electrical tubes MRB (metal and rigid) are packaged in a 3 meter length, with 2 threaded ends, and 1 screwed sleeve, and as all the tubes used for the base and the pole are threaded, you'll have no choice but to salvage some others. (who's talking about buying ?)
  • Be careful, the reference of these tubes does not correspond to the diameter which is given between brackets.
  • The 4 sleeves of the base, arranged in cross, will be soldered around a 1 meter tube (threaded end at the top) and sightly tilted. (put a wedge below)
  • This slope will enable your standard lamp to be stable, once the 4 tubes (400 mm) are screwed.
  • The wing nuts are stuck with some cyanolite on the Allen screws without head, (be careful, your fingers !) and wear security glasses when using this kind of glue. (we never take too much care !)
  • The stoppers are plastic caps which are forced on the end of the tubes. (protection of the electric wire when you set it up)
  • Paint in black the hard solderings.
  • The 5 meters Syndex extensions will have the female plug cut (it's easier) and slid first into the 8 mm hole of the T-pieces.
  • The Paris tube (17) is a brass tube which is already threaded and which can be perfectly screwed in the sockets and the bends of the piping.
  • 20 mm pieces will be enough (10 mm on both sides) and the blocking will be done with the small lateral screw of the sockets E27.

    Option :
  • The extensions are centered on a Teko box with the dimmer switch. It's not essantial, but quite useful when there are 100 watts spots and we want a filtered light.

    Some details :
  • When we talk about soldering with a blow lang (oxygene + acetylene), the metal you need is the same as the pieces to be soldered. (scrap rods)
  • When we talk about hard-solderings, the metal you need is differend. (coated brass rods)
  • E27 means : E as Edison, with screw, and 27 is the diameter of the socket.
  • B22 means : B as bayonet, and 22 is the diameter of the socket.
  • The lamp is made up a bulb and a socket.
  • 3/8 of inch or 12-17 mm for a tube. (interior and outside diameter)
