Is it cheaper to leave LED lights on
The Energy Saving Trust's top tip for reducing the amount of money you spend on lighting is to replace incandescent and halogen bulbs with LED Lights. Halogens were already an improvement on the older incandescent bulbs and compact fluorescent lamps (CFLs) are also more efficient and longer lasting. But LEDs are king.
