This impressive crystal look christmas tree lamp can be powered by 3 x aaa batteries or 4.5v adaptor so can be used as a wire free table decoration, or plugged in and used as a festive table lamp. The fir tree style lamp stands at 31cm tall and simply switches on and off at the bottom with a slide switch. Rather than turning the lamp on and off, you also have the option of sliding the switch to 'timer mode', it will then light for 6 hours, switch off for 18 hours, and come on at the same time every day on the same 24 hour cycle, perfect for just setting up once and letting it operate itself.
