Understanding LED Lighting Technology

Professor Markham from Tool Barn University discusses the evolution of lighting due to stricter federal energy standards. The video covers the characteristics and efficiency of halogen, CFL, and LED lights, highlighting the heat issues with halogen and the energy efficiency of LEDs. It also provides guidance on purchasing bulbs based on lumens rather than wattage, emphasizing the efficiency of LEDs compared to incandescent bulbs.
