![]() That’s why the LCV became the first road-registered vehicle with full LED tail lights. Land Rover has registered the concept vehicle to drive on public roads. That’s why the concept vehicle was equipped with standard tungsten filament bulbs for headlights and interior lighting. The experiment appeared to be too expensive and did not meet the budget, so using LEDs for the other car lighting was impossible. The theory of the engineers was to use a combination of Red, Green, and Blue LEDs (RGB) to get white LED color. ![]() The Blue LED technology had just arrived and was extremely expensive. Making the reverse light was a real challenge since white LEDs were not available in the early 1990s. The rear tail light system was completely LED. Yet, because of the budget restrictions, the production investigations had to be cut. The whole lighting system of the LCV project was supposed to be LED. It’s fair to say, that the first series of LCV prototypes were based on the LR Defender 90.Įven though this vehicle looks somewhat retro, it is very technologically advanced and more aerodynamic, than the Defender 90. It was designed when the company was seriously investigating the option of a more lightweight vehicle that featured innovative specifications along with a smaller body and recognizable Land Rover design. LCV stands for the ‘Light Concept Vehicle’. The first vehicle that featured tail lights where every bulb was LED was a concept car, Land Rover LCV 2/3. Here is an interesting fact about the first usage of LED bulbs in automotive lighting. The First Vehicle with All-LED Tail Lights That’s why, to keep as close to the topic as we can, we will discuss only those, that are normally used for the LEDs. Different kinds of automotive bulbs may differ in terms of color temperatures. The same happens when people select different color outputs for the low beams and fog lights that do not match when installed on the vehicle. When LED bulbs are ordered in portions, some of them differ in color from the previous ones, which may look wrong as a result. As a rule, people do not replace the whole bunch of bulbs inside their vehicles at once. LED headlight upgrades are especially popular, both as replacements for headlight bulbs and as replacements for the bulbs used in the vehicle interior and exterior. In 2011, the US Federal Trade Commission started requiring manufacturers of compact fluorescent, incandescent and LED bulbs to use lumens as an indication of how bright a bulb will be.We keep getting a lot of questions on what is the difference between 5000k vs 6000k LEDs is, that’s why we decided to explain the key aspects that will help our readers understand the color temperature basics. It just hasn't been predominantly displayed on packaging until recently. It's a rating that's been used for decades as a measurement of how much light a bulb (or anything else) emits. Measuring in lumens isn't a new concept designed just for LEDs. This gives you a more accurate indication of how much light to expect from an LED. To fix the problem, bulb companies have started using lumens to rate bulbs. This means it's useless to use watts to determine brightness. LEDs are designed to use less energy and naturally have a lower watt rating. In fact, a 60-watt LED just may blind you. ![]() An LED that uses 60 watts is in no way comparable to an incandescent bulb that uses 60 watts. That rule doesn't apply to LED bulbs, though. ![]() When buying an incandescent bulb, the watts rating gives consumers a good indication of how bright a bulb is. Luckily, it's simple enough to sort out any confusion. With today's LED bulbs, brightness is measured in lumens.īut, what the heck is a lumen? How is it different than a watt? How can you tell which LED bulb you need for your lamps and lighting fixtures? , you could determine the bulb's brightness by the number of watts printed on the package. ![]()

Thank you for sharing the LED brightness chart. It's a valuable resource for understanding the different levels of brightness offered by LED lights.
