Here’s something most people overlook, heat output. Old-school bulbs don’t just light up your space, they also heat it up. That may not sound like a big deal, but it is. Extra heat in your home forces your air conditioning system to work harder, especially during summer months. Retrofit recessed lighting with LED technology emits very little heat. That means your rooms stay cooler, and your AC unit doesn’t have to battle unnecessary warmth. This helps reduce your cooling costs and keeps your home more comfortable year-round.
