The first part of the guide is important to follow or the sphere may never attach in its correct orientation, as it is possible to install it 90 degrees the wrong way.

Screw the translucent blue matrix onto the lower sphere all the way.

Find the part of the sphere pictured, and rotate the blue matrix part back so the tab is aligned above the middle of the part pictured.

Try and keep this alignment fairly exact, as in the next step we will be pushing the upper sphere onto it so the tabs snap in place.

Now align the top and bottom parts of the sphere. The part of the sphere with the three vertical black lines is easiest to use.

Now firmly push the lower sphere onto the lower piece keeping it aligned. It should snap into place. Now undo it.

Now unscrew the top part of the sphere.

Pull the USB cable of the lamp through the hole in the bottom of the lower sphere and insert the lamp into the base keeping the cable in the guide.

Then place the outer metal part as pictured so the arrows are aligned. It is only possible to insert it one way around.
