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.
Complete article at this link Light Fights: LED vs. HIDLEDs 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…
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.
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.
