I bought the 60W version as a replacement for an external, mains wired uplighter that has failed. I'm very pleased with the SOLLUX uplighter; it's extremely bright and lights up the back of my house very well. The light output is very "cold" and it would be nice if there was a way of switching the colour temperature to make it warmer. At 50% brightness the light holds its charge really well but at 100% it seems to run down fairly quickly. The only real issue I've had is that after a spell of rain, there seems to be a layer of very fine condensation on the inside of the glass. This may be because the light is lying flat on the floor rather than being angled upwards.
