LED Bulbs use 90% less energy than standard bulbs, generate light at 87.2 degrees and have a lifespan of an estimated 15,000 hours. Standard bulbs typically generate light at 335.4 degrees and have a lifespan of 1,000 hours.
LEDs do cost more up front but in order to match a typical 13.5 year life span of an LED bulb, a person would need to purchase 14 standard bulbs and would spend approximately $80 more in energy costs. Not to mention the cost savings in terms of the labor to switch out all of the lights.
So while the upfront costs of LED bulbs are higher, the long term energy and cost savings can be significant for businesses that require significant lighting.
