finally - some updates - making a lamp

One of the problems with modern designs is that a lot of the work that goes into making something that looks clean and sleek is not visible. I was making a couple of lights today for an order and took some photos of part of the process - making the base.
Here's a shot of  one I made several years ago
and here are some of the steps to make one: I left out the trivial ones like hack-sawing through 1/2 inch (12.5mm) aluminium bar and cutting the acrylic tubing. Clicking on any photo should enlarge it.
smooth ends

centre drill hole for wires

enlarge hole and drill through base


turn shoulder on base so acrylic tube will fit snugly, but won't split if the aluminium expands with the heat of the light or changes in room temperature. The acrylic also expands, but at a different rate.

test fit and turn some more
clean up the exterior

on my mill, mill channel for power cord so base will sit flat

now just assemble the LED electronics and they're done. If you look REALLY closely you can see the groove in the base of the right hand light.
 nothing to it! I wish

  3. Thanks for sharing your process. I would like to make some light fixtures for my latest project. A simple shop light and outside lamps. What kind of LEDs do you use? I'm thinking about the Evans Designs lights. I've used them before, but did not get the results I had hoped for. Any suggestions?

  4. Kathi,

    I usually make up my LED components from individual parts. Often the LEDs come from Ngineering (I resell his products because I like them so much) and I wire the SMD (surface mount - no leads so you solder directly onto the LED) LED to a very small DC power source. That way I can have the actual light in one place and the power source hidden somewhere else.
