Good morning. Your staff could not have been more helpful. The lights are just what I wanted, they look great. I do however have one problem, the other night we took some of them in to our hot tub, one did not colour change it just stayed blue and one got water in almost immediately and stopped working, so of course I thought I had not tightened it up enough. But in the morning I opened them up and they all had water in so I do not think it was because I didn't tighten them as I was careful. The batteries in all four were rusted, when I dried them out some of them began to work again but I dare not take them in the hot tub again. So please could you send me two warm white to replace the two faulty ones. Many thanks, Debbie Price (Mrs)
