Best source of garden lighting is the sun. Places like Arizona in the US are probably the best sources to get long periods of light from the sun to your garden :)

So tow your garden out there asap!! Can't afford garden lights so sorry can't be of serious help!

have you tried B and Q we got some large garden lights from there last year which you can change the bulbs to different colours, it looks very pretty, I have just looked on there website and they have a good selection. I would not recommend solar lights as they are not very bright at all.

I looked at B&Q and wasn't too impressed at the quality, I also try to stay clear of anything made in China which I must admit is near impossible these days.

Good luck with your search. I hope you manage to find some.
