Differences between your GTR Lighting Generation 2 and Generation 3 LED Headlight Bulbs

In March 2019, GTR Lighting released the next Generation LED headlight bulbs that have been the 2nd LED headlight bulbs from GTR Lighting. (The very first released a year earlier.) These 2nd Generation Bulbs were 1,000 lumen brighter and featured a distinctive color shield system to change the color from the light output. This new generation of LED headlight bulbs also created a beam pattern which was more usable and focused. These 2nd generation bulbs were widely received and we found results specifically well within the 14-17 Toyota Tundra. Then when we began to hear rumors from GTR Lighting that they are releasing an even better generation we got excited! In the following paragraphs, we'll point out the differences between your 2nd Generation and the newly released GTR Lighting Ultra Series (Third generation) LED Headlight Bulbs.


Before we dive in to the specification differences, one thing to explain is the body from the 3rd generation bulbs. Then 3rd generation Ultra Series bulb uses a fan-less design for cooling the bulb. The initial 1st generation and Generation 2 bulbs used a fan within the base of the bulb to drag away heat and cool the bulb. The fan in the first generation model proved helpful enough for cooling the bulb, but we're excited for a new air conditioning that does not involve a fan that may potentially fail. The new Ultra Series LED Bulb uses a hollow base that enables for convection cooling and air movement with the base.

The other huge difference would be that the 2nd generation used an “All-In-One” style driver technology. However convenient it was, it increased the mounting depth required to run the bulbs. The brand new GEN 3 uses an external driver and sports a half-inch shorter heat sink which means it will fit way more applications than it's predecessor!

The capability to change the colour of the sunshine output around the 2nd generation bulbs really was a distinctive feature that lots of owners loved. It is also an element you won't find in this newest 3rd generation of LED bulbs; the next generation Ultra Series bulbs have an unchangeable 6,000K color. Even though this color is beautiful, bright, and clean white, some owners might be disappointed in the single-color choice. When inquired about the modification GTR Lighting admitted that utilizing a glass shield around the LEDs on the old bulbs increased operating temperature and may have led some models to premature failure.

But a difference between 2nd and 3rd generation bulbs that won't disappoint is light output. The next generation bulbs had an advertised 3,600 Lumen output while the 3rd generation bulbs have a 3,700 Lumen output. “But measuring only one hundred lumen difference” you say. Correct, but let's look at the lux numbers:

This picture was taken far away of 25 feet with the stock halogen bulbs, 2nd generation LED, and Third generation Ultra-Series LED bulbs all placed within the same headlight housing. As you can see, the lux amount produced from the Ultra Series bulb is 1,000 lux more than from the 2nd generation bulb. Why is this important and just what even is Lux? Well, allow me to explain.

Lumen may be the quantity of total light created from a bulb. So the greater lumen is produced the brighter an easy is, but Lumen is just one factor in determining usable brightness. Lux is when usable light is determined. As you can see during these test shots, the 2nd generation bulb which has 3,600 lumen only produces 360 Lux and also the GEN 3 bulb which has 3,700 lumen produces 1,360 lux. How can it create a lot more lux with simply 100 extra lumen? What's the difference? Well, look closely at the beam pattern pictures. The next generation bulb creates a beam pattern having a very distinct and very intense hotspot. While you look at the 2nd generation bulb beam pattern you'll see that this hotspot is small and more dim. Lux is a measure of these hotspots. Lux is measured inside the beam pattern at a distance of 25 feet and measures the quantity of light that's actually being thrown from the headlight down the road. Allow me to place it this way, a bulb with high lumen amounts might be unfocused and produce low lux amounts as a result. However, a bulb with the same amount of lumen that is capable of being focused well inside a headlight can establish high Lux amounts. The major difference we see here in usable light output is not really a matter of Lumen, but a matter of precise focus and the resulting lux. An enormous difference we have seen between the 2nd generation and also the Third generation bulbs is the ability of the 3rd generation bulbs to produce a better-focused beam pattern versus the 2nd generation bulbs. Here's why:

LED chip technologies have greatly improved because the early days of LED headlight bulbs. Take a look at the main difference between your GTR Lighting 2nd and Third generation LED Headlight Bulb chips. The 2nd generation bulbs featured CREE XT-E LED Chips. The new Ultra Series Third generation bulbs feature Lumileds Luxeon Z ES Chips. These new Lumileds chips are much smaller and may really be shaped right into a configuration that more closely resembles the footprint of the standard halogen bulb. The design and layout of those new Ultra Series bulbs are what create a beam pattern more much like a stock halogen bulb.
