NMLD.. Installatin Types and Accessories

 

All our high-pressure discharge lamp light fittings are supplied with separate power

 unit enclosure.

This is of outmost importance to prevent direct heat from the lamp damaging the ballast,

starter and capacitor if they were all to be placed in the same enclosure with the lamp.
