I bought 2 sets of solar decking lights 2 years ago. They have been good but this winter they started to fail The LEDS were fine but the solar panels and batteries were finished. I phoned to purchase 2 new solar panels as it said on the website that they were replaceable. I was told this was not the case so I had to buy 2 new full sets. I was given a 5% discount. So I now have working lights again but 12 new LEDs which I cannot use unless I buy another set!! So overall a good product just let down by the detail. You should be able to just buy the solar panels.
