Fault finding on a series circuit for LED down lights - Impromptu recording

We were at this property a couple of weeks back and asked to look at some lights which had failed. Noticed that they should be much brighter than they are and that the driver is undersized for the demand. A few of you on instagram wanted a video of how we got the up and running and to be honest I forgot about it until we were onsite! So apologies for the wobbly content and poor framing. We know it didn’t explain the series wiring well, so we have planned an in-depth video filmed in out studio to help explain this. Give us a few weeks, hope you can take something away from the video. Enjoy!
