Speaking to Zac Newton at the Fans Assembly he confirmed that the contractors are to return to complete the installation of the lights under the Mayflower roof, hopefully before the next evening game. There are a fewer number under the Mayflower roof currently compared to the Lyndhurst. The post lights will be removed at that time too. The contractors are the ones who have upgraded Old Trafford's lights and many others around the country.
When completed the lights will be Championship standard. They are League 1 standard now and a massive improvement on the previous installation. However, on viewing the highlights of the game they did appear darker than at the game but I suspect that was more of a technical issue with the cameras rather than the brightness of the lights themselves.
