Having not been to Sutton United for many years until the Tonbridge Angels game, I thought the floodlights looked dim compared with some other RPL grounds I have visited. Is there a dimming switch? I'll bring a torch next time. [and no, I wasn't wearing shades ] Mark

You may well have a point there.When we acquired the lights i understood they were the best in nonleague football at the time.Obviously teams like Luton are there now but i do wonder if they have been dimmed over time.Maybe someone in the know could advise.

I think they probably need cleaning.

The new lights went up in summer 2001. They are low energy and directional, meaning more light gets onto the pitch and doesn't spill into the night sky. It is because of this that the lights look dim from the side, that surprised me from the day they were first used. It doesn’t mean they are dim on the pitch, we comfortably beat the required lighting levels.
They are good lights but we never claimed they were the best in non-league football.
All lamps of this type loose efficiency over time and the light level drops off. A good clean restores some of the brightness and we carry this out each year, the next service and clean is due soon. Even when cleaned though, the brightness still falls over time. There are various time-efficiency curves used in the lighting industry to work out when the best time is to change the lamps. We have changed the odd lamp over the years because of failure but we are nearing the stage when we will have to consider a complete re-lamping.
In energy terms, modern lamps are not that expensive to run. From memory our total lighting load is around 50kw, excluding control gear losses, so the cost to have them on for 2 hours is approximately £10.
One advantage of the towers and fittings we now have is that it is relatively easy to improve the lighting by switching to a different type of lamp.

Thankyou for this most considered reply.
I would not normally think about the lighting - it's just something we take for granted!
