Recently we have invested in a lot of landscape lighting, as well as having coloured LEDs installed above the cornicing in the ballroom, which can be set to any colour on the spectrum (from subtle to not so subtle!).
Here are some photos:

Above and Below: The Super-bright 60 lumen spotlights available from Duracell USA, which are a big advance upon traditional solar garden lights (which are usually about 5 - 8 lumens).
As you can see, they are plenty powerful for our needs, and have let us light up many of the garden features around the 30 acres, without us having to run cabling around that sized area...
Two of them powerful enough to light up the folly by night too...
We did a lot of research about LED lighting when we bought the bulbs for the inside of the manor. It was a compromise between efficiency and longevity; and ambiance. Even with the warmest colour available on the market (2800K), they still do not create the same ambiance as a good old fashioned incandescent Tungsten bulb (but running over 400 of these in a house would not be a sensible idea). Here is an indicator as to the colour warmth of different lights...
With yellow filters on the outdoor lights one can almost achieve the right colour...
Here is a little video clip of the different glows we can achieve in the ballroom. If there is a colour theme to your wedding or event we can match it perfectly, or let the lights cycle through colours if you wish to use the ballroom as a dance floor.
Note: The flickering is only due to recording on a digital camera, and is not visible in real life.
