This recent article presents what I consider to be a pretty fair and accurate comparison of the current state (as of early 2017) of HID vs LED lighting for vehicles.

LEDs have gotten a great deal of attention lately, but do they really have what it takes to outperform the tried-and-true favorites in the HID category? Let’s find out…

Applications

In the past, HID lights were often the go-to choice in applications where a large amount of visible light was needed in a sizeable area. For instance, they’re often found in streetlights, gymnasiums, stadiums, warehouses, and in high-ceilinged buildings. HID lights, however, are not a perfect solution as the light they produce isn’t always pleasing to the eye and many require an extended warm up time. Thanks to technological advancements, LEDs are now a viable alternative in many HID applications – although, they also come with their own set of pros and cons.

Overview

Before we get into the advantages and disadvantages of HIDs and LEDs, let’s first get a better idea of what we’re dealing with by reviewing how each light operates.

That article is HORRIBLY skewed in favor of LEDs. It's partially truthful but isn't always factual. LED bulb swaps aren't the way to go. They use facts from the terribly cheap HID kits of eBay for efficiency numbers and warm up times, which are still horribly exaggerated and state a high cost. So they use dealership prices as a example but base "facts" on cheap eBay kits. Laughable. HIDs are still the way to go in a projector. High end halogen for halogen housings. Stick with the light source the housing was designed for and you'll get the best light available without a retrofit.

......HID vs LED lighting for vehicles.
I saw no mention of vehicles, or specifically headlights. Premier Lighting does not sell headlamps. I'm not sure this article substantially applies to automotive applications.

What are you talking about? Ebay kits? Dealership prices? Did we read the same article?

In a auto capacity this article is full of fallacies. Even warm up times for other applications are made to sound much worse than they actually are.
