After switching all my lamps to LED light bulbs, I was annoyed by the fact that most of these bulbs predominantly emit light into the forward hemisphere. Only very little light makes it into the opposite direction. To some degree this is ameliorated by the lamp's screen acting as a diffuser, but it's still far from ideal. To achieve a decent light level for reading, you have to use a very strong light source. However, most of that light goes into the room instead of downwards onto your book, creating a less than comfy atmosphere. I had to fix this.

Step 1: Taking the Lamp Apart and Back Together Again

The bottom part of the lamp simply unscrews. The heavy foot comes off from the center pipe, the center pipe unscrews from the swivel joint. It is here where one new opening should be created. As you can see, there is plenty of room to insert a protective piece of wood or plastic while working the metal. The mains wiring must be protected from getting damaged.

If for whatever reason the mains wiring should get damaged, the lamp is not safe to operate anymore. The wiring must be repaired or replaced by a qualified person.

The next step is to remove the spring. It is a very strong one, a real bastard. Use a piece of strong string as shown in the images to pop it off. Place the string on top of the spring, close to where the hook grabs the little horizontal cross-brace. Take a firm hold of the string and lamp and pull. If it doesn't move, pull harder. Eventually it will move and you can pull it free.

Then unscrew the two tensioning nuts. This will free the rod that needs to be modified. Don't loose the thin metal washers! The remaining part of the lamp's upper body (2nd rod + swivel joint) holds the mains wiring.

Once you're done with the metal work (see later steps), re-assemble the lamp in reverse order. Make sure the mains wires are not pinched. Getting the spring back on will again require a piece of strong string. Use it to pull the spring's hook back over the cross-brace.

<p>Great project!! Great explanation!!</p><p>Where did you make the board?</p><p>Regards,</p>
<p>Great modification. I wish I had come across this before. Although I didn't add another light such as you have here, I added an ipad holder to position it while on the couch or standing at the kitchen. Taking that spring off almost drove me nuts! Clever thing with the rope. </p>
<p>Yes, that spring has a special place in my memory :-)</p>
<p>Good work!</p>
<p>i don't want to seem impolite but only in step 4 i understood building a circuit with a microprocessor was needed. <br>It is still not clear to me if the blue regulator panel also had to be bought and if so where or if it is part of the lamp.<br>Perhaps the readability instructable would be helped by initially stating what you are going to do rather than just say that you are going to fix a ligthing problem.<br><br>Putting the BOM on the first page also would help</p><p>it actually still isnt clear to me what in fact you did with this lamp</p>
<p>I took the lamp apart, machined 3 new openings for additional wires, reassembled it, added new wires, added the 'reading light' lamp module and wired it up. The lamp module is my design, I had the circuit boards made, assembled it myself, wrote the code. The blue board can be seen in almost all of the images showing the top of the lamp, attached to the lamp with black Velcro tape. Maybe you haven't seen all of the images yet.</p>
<p>I think I did. I didn&rsquo;t want to criticize your effort, just give some feedback I found it hard to understand what you were exactly doing. that's all</p>
