In the ZIP archive you will find, beside these instructions, other two files:

1) "Numenor_TanningBed_main.package": it must be extracted to your Downloads folder.

2) "numenorSolarium_Light.nlo": this file contains the custom light definition needed for the solarium to work properly.
This ".nlo" file isn't actually needed: the tanning bed already contains the information for the custom light and works even without the .nlo file.
But there is a bug in the game (not in the tanning bed): when you exit the lot and then re-enter it (for instance, when you visit a community lot and then you go back home), the custom light doesn't work any more. The bed itself still glows in purple, but the surrounding walls are not hit by the purple light.

In order to fix this bug, YOU MUST INSTALL the support for the custom lights provided by the SCRIPTORIUM (get it at http://www.modthesims2.com/showthread.php?t=192613);
then with the Scriptorium installed, you will find in your Downloads a link named "Scriptorium_CustomLights": open it and put in that folder the file "numenorSolarium_Light.nlo"
