[VIDEO] Wiring a 7 terminal ballast to 6 terminal

Whilst the number of high Frequency ballast is reducing there are still lots of them out there. We are still getting calls (which isnt a problem by the way) from engineers who have gone to replace a ballast in an old fitting and they have taken out a 7 terminal ballast from a fitting and the newly supplied ballast only has 6 terminals on making the swapout slightly more difficult. This example should make it easy for you to follow and swap out those ballasts but as always if you are still struggling, call us on 0151 480 4000 and we will be very glad to help.
