L.E.D

I have one of these Paul and I'm very pleased with it, it's so convenient. I use it for up to an hour or more depending on the time of year etc. I don't think I use it as long as I used to use the Britespark. It was well worth getting the rechargeable/cordless one.
When I went to the shop to look at them (Southport) I had in mind a different one, but found the white lights too bright. I like the blue ones better. You can choose a lower intensity and treat for longer, which is what I do sometimes.
