You need to take into account the length of the track and that of each spotlight, as well as the driver. Only one driver can be installed on a track system, even if it is made up of several tracks connected together. You must therefore consider the maximum wattage supported by a single driver.
For example, for a track system fitted with a 100W driver, you can install up to 20 spots with an output of 5W each or up to 14 spots with an output of 7W.
The drivers in our Lyne collection support a power of 100W or 150W. However, we always recommend checking this information on the driver's product page before purchasing.
