1. LED Bulbs are Affordable
But these days, prices have plummeted, and while LEDs are still more expensive than other technologies, sometimes the difference isn't much. That's definitely the case with A-shape bulbs replacing your typical household bulb. And when you factor in the other benefits, the initial price difference becomes a moot point.
2. LED Bulbs will Save You Money
This is because they're the most energy efficient bulbs available. Replace a 60 watt A19 incandescent used for 3 hours a day at 11 cents per kWh and you're likely to save around 55 kW and around $6 per year. Now imagine the savings against an HID bulb used in a parking lot for 12 hours per night. (We've estimated those savings to be close to $200 per year in some cases.)
Additional savings come from the longevity of LED bulbs. See the next point for details.
3. LED Bulbs are Rated to Keep Going ... and Going ...
1) You'll have reduced costs from buying additional bulbs.
2) You'll have reduced costs from replacing bulbs. Replacements aren't difficult at home in table lamps or low-hanging chandeliers; but what about bulbs in flush mount ceiling fixtures or hard-to-reach foyer chandeliers? Now consider what it takes for a business to replace high bay or parking lot lighting. Real time and costs are involved, but less so when using LEDs.
BONUS: Using fewer bulbs means producing less waste when lamps reach life end.
4. Lumen Maintenance
So while they cost less than LEDs up front, the lumen maintenance of metal halides is important to understand if you're trying to control lighting levels. You may need to purchase based on "mean lumens" rather than initial lumens, which means buying bulbs with higher wattage to address the light loss (and continuing to pay for that extra energy).
Meanwhile, LEDs are known to maintain close to 90% of their initial lumens at half their rated lives, and more than 70% throughout their lives, so you can choose a lower wattage and rely on initial lumens for light output, never paying more than you need to in energy costs.
5. LEDs Provide Directional Lighting
6. LED Bulbs are Instant On
Like incandescent and halogen bulbs, LEDs come to full brightness as soon as you turn them on. CFLs usually take about a minute to reach full brightness, and HID bulbs can take several minutes. (HIDs also need a cool down time, called a "restrike" time, when you turn them off before you can turn them back on.)
7. LED Bulbs are Fine with Frequent On/Off
On/off cycles impact the longevity of most bulbs. This is definitely the case with CFLs, whose lives can be cut in half when turned on and off frequently. But this cycling doesn't seem to have much impact on the life of LEDs.
8. LED Bulbs Usually Dim Well
9. LED Bulbs Don't Emit Much Heat or UV
Also, LEDs do not emit much or any UV radiation, which was a point of health concern for many people when it came to CFL lighting.
10. LED Bulbs are Mercury Free
Another point of concern many people have with CFLs is that they contain mercury, a known toxic substance. Even the EPA offers a strong caution about how to handle a broken CFL bulb. This isn't a problem with LEDs, as they contain no mercury.
11. LED Bulbs Work Well in the Cold
Yet another concern with CFLs has been their poor performance in cold weather. This wasn't an issue for incandescent and halogen bulbs, but with LEDs, we now have a super efficient lighting option that performs in cold weather without a problem.
12. LED Lights Come in a Variety of Color Temperatures
For comparison, incandescent bulbs are around 2700K and halogens are typically between 2700K and 3000K.
LEDs, though, provide options from a warm 2400K to a cool 5000K. And select LEDs will even get warmer as you dim them, similar to the way an incandescent bulb does.
13. LED Lights Render Colors Well
The bottom line is that LED lighting can rank well on the CRI scale, but that all LEDs do a very good job of rendering colors. And when you're comparing LED to HID lighting options, LED is the hands-down winner when it comes to CRI.
14. LED Lights are Durable
