No matter what the destination was the lamp in the set necessarily includes shade or reflector that limits the dispersion of the luminous flux and guide him to a functionally important site. Hence the increased demand in stores electronics on unusual chandeliers, sconces, floor lamps. And many are taken manufacturing them yourself.
Romanian journal "Technium offers universal application possibilities household lamp that gives enough objective luminous flux and at the same time with no shade. These properties are due to the use of relatively new type light bulbs - batten. The fact is that when big enough already variant the performance of the lamp in the soffit differs from the usual two main features: a large flask of mushroom-like form and deposited inside reflecting or coloring layer. It acts as a reflector or the lampshade. On the basis of the lamp batten can be made table, ceiling or wall lamps and floor lamps. Moreover, the main unit comprising a casing with cartridge and bulb, for all options the same.
The cartridge uses a standard, better - porcelain, since the large the lamp power (they do happen from 60 to 500 watts) possible over-heating it. It set on its own nut in the cylindrical case, made from sheet metal thickness of 1 mm. For better cooling of the workpiece is desirable perforate, nasverliv or breaking (from the front) a few rows holes. Bend it into a cylinder on a round mandrel, probajte joint, and on both the sides of the seam in the middle of a length of casing attach two eyelets under hinge the connection to the rack. With one of the ends of the casing attach with rivets or solder a strip of sheet metal bracket cartridge. It remains to establish the cartridge and screw in a lamp - lighting unit is ready.

Now you can get any lamp, it is enough to connect with the lugs of the casing corresponding to the rack or bracket. The figure shows hints of possible solutions.
