In business settings, the move from other lighting technologies to LED lights makes more financial sense all the time. LEDs continue to fall in price while increasing in quality, including light output (lumens) per watt (which reduces energy costs).
This financial sense isn't limited to the initial cost of bulbs, but to the total cost of bulbs over time, with LED lamps typically lasting for years beyond other lights. In the case of the high wattage lamps we're discussing in this post, this means buying just one LED for every 2 or 3 metal halide lamps; or one LED for approximately every 5 or more halogen lamps.
Maybe even more important is the time / cost of actually replacing these lamps. High wattage lamps are generally used in high fixtures that are difficult to reach, involving lifts to replace them. So it's no small thing when -- under usage of 12 hours a day -- a halogen will need to be replaced every year on average; a metal halide every 2-3 years; and an LED every 5 years or more. This is a huge advantage to using LED bulbs.
So let's take a look at a particular PAR38 LED replacement option for both halogens and metal halides.
