Prior to the calculation, it is necessary for at least one row of luminaires to have been positioned. To do this, you should go to the ReluxTunnel ribbon. 

You should then select the luminaire row option. When this option is activated in the project for the first time, the Product selection window for the selection 

of a luminaire type will automatically open. It is also possible to proceed via the standard route for selecting a luminaire.

Positioning a new luminaire row

Product selector

Note:  In the Product selection window, you can select the Individual luminaire tab in order to import individual Eulumdat files. 

Digital light distribution curves from a wide range of manufacturers can then be imported in a highly flexible manner.

In the standard case, there will be a light distribution curve for each luminaire/lamp type, which you can read in. 

If you only have one light distribution curve and wish to use this with different lamps, then you must read in this light distribution curve as often as required, 

and, in the Product selection window, click on the luminaires to be modified. You should next click on the Modify type button; you can then open the Modify luminaire window 

where you can change the desired data (e.g. the luminaire name and number, the lamp type, lamp power, luminous flux and installed power). 

After the change, has been made, it is important for the lamps read in to display different luminous fluxes in line with the lamp employed.

Modify luminaire

After entering one or more luminaires in the project, you should close the luminaire selection. The Options window will then open automatically. 

At a subsequent point in time, you can also open this window directly in the Tunnel ribbon bar by means of the icon.

Here you have the opportunity to define alternative equipment and different regulating steps.

In the Alternative equipment dialog, it is possible to classify the luminaire types that have been read in as adaptation or interior lighting. 

Under Unused luminaires you can see all the luminaire types that have been read in and not allocated. 

The Adaptation button can be used to allocate a luminaire type to the adaptation lighting, while the Interior button will allocate a luminaire to interior lighting. 

The Delete button is used to cancel the allocation, and the luminaire type will appear under Unused luminaires again.

Three allocated luminaire types and two non-allocated luminaire types.

It is possible to make more than one entry in each field. The order in which the luminaires are entered does not matter, since this will be reconfigured automatically 

on the basis of the luminous flux each time the Options window is closed and opened. Each luminaire type can only be used once.

In the Maintenance factor input field, all the luminaires can be allocated the same maintenance factor. 

By using the individual button, the maintenance factor for each luminaire can also be specified separately.

If you see that certain luminaire types are still missing, you can press the Select luminaires button to go directly to the Product selection window and read in new luminaire types.
