How long can you safely leave exterior Christmas lights on each night, and do you set timers or smart controls so they turn off automatically?
Quick Answer
You can safely keep your exterior Christmas lights glowing from dusk until dawn each night. Modern LED strands stay cool and energy-efficient, but Lights Over Atlanta always programs a weather-rated timer so your holiday display turns itself off automatically and restarts tomorrow evening.
Detailed Answer
Lights Over Atlanta designs displays that are safe enough to shine all night long. Modern UL-listed LED strings draw 80–90 % less power and emit very little heat, so there’s no technical harm if they stay on 24/7. For most metro Atlanta homes that means your roofline, trees, and wreaths glow from dusk until dawn during the holidays.
To make that effortless, every residential or commercial package from our holiday lighting installer team includes an automatic timer and remote control.
The result: you never worry about switches or wasted electricity. Your display dazzles at peak evening hours and powers down like clockwork—saving on seasonal lighting costs while extending every bulb’s life.
