There are many variables, so lets dig in! However, if today’s LED technology is used as a benchmark, halogen lamps have almost nothing but disadvantages. In the beginning, all we had was the standard, incandescent light bulb. Both CFL bulbs and LED bulbs were made as an energy efficient alternative to previous lighting fixtures. So we are going to compare equivalent CFL and LED lamps. Fluorescent, or CFL bulbs, are more energy efficient than incandescent bulbs, but not as efficient as LEDs. <>>> � Q�?��"�c���D�$ �@���j����n�����;�79��j��j�.m:���N�&u The size of LED bulb is usually smaller than a CFL bulb.
