our set of two solar powered ?tiffany? inspired lamps are made from coloured glass in a tulip design & give out a truly stunning light. solar powered to charge simply place on a sunny windowsill (or directly in the sun in the garden ? & as with all solar products the more sun they get the better they will work!) & the discreet solar panel on the top converts the suns rays into free renewable energy that then gets stored in the built in battery ready to automatically switch on the leds at dusk. portable once naturally charged our lamps can be used both indoors & outdoors. measure h 20cm xw 15cm (8in x 6in).
