Well they arrived today and first impressions are very good. Really well packaged and the build quality looks very good. Allen keys are included for the heatsink and for the adjustment of the bulb. There are even cable ties included for the control boxes. Communication and customer service is so far faultless. When I placed my order I only ordered one extension lead as I assumed they came as a pair. This was communicated to me in an email, but they said they'd throw in another one free of charge.
Just got to get them installed and tested now!
