How effective are lensless LED headlights?

Lensless LED headlights are not very effective. Here are the specific details about LED headlights: 1. Light pattern: If the original vehicle does not have a lens, LED headlights lack a low beam with a built-in cutoff function, resulting in a light pattern without a cutoff. If the original vehicle does not have a lens but you want a distinct cutoff in the light pattern, you must install LED bulbs with a built-in cutoff function for the low beam. 2. Color temperature: The commonly used color temperatures for LED headlights (listed in order of usage frequency) are 6000K pure white light, 3000K golden light, and 4300K yellow-white light. During rainy or foggy weather, yellow or golden light must be used, not white or yellow-white light. Therefore, in rainy or foggy conditions, you can use the original halogen bulbs or LED yellow or golden light, but not xenon lights, as xenon lights do not have yellow light. 3. Current: The power of LED headlights is generally around 30W, and the current is typically around 2.2A. 4. Durability: The temperature of LED headlight bulbs ranges from 70-90 degrees Celsius. The higher the temperature, the faster the light decay and the shorter the lifespan. However, LED bulbs are much more durable than the original halogen bulbs.
I think the overall performance of lens-less LED headlights is quite good. Not only are they bright enough, but they also save a lot of electricity. I've driven many cars, and with these lights installed, the night driving visibility is much clearer. The light distribution is even without hot spots, making it feel like daytime. However, they also have drawbacks. Without lens focusing, there might be some glare issues during turns or in rainy/snowy weather, affecting the visibility of oncoming vehicles. Compared to traditional halogen lights, they have a longer lifespan, almost never requiring bulb replacements, and less maintenance. Installation is also convenient, as most modern car models come with this design. If you frequently drive at night, they can significantly improve safety and reduce fatigue. Just remember to regularly check and adjust the angle to avoid scattering issues.
Honestly, the lens-free LED headlights on my car have performed really well over the past two years. They provide uniform brightness and wide coverage while driving, especially offering clear visibility without glare on highways. Compared to traditional headlights, they're more energy-efficient and eco-friendly, saving me a noticeable amount on electricity bills each month. The downside is that the light tends to scatter on cloudy or foggy days, making it harder to see roadside details clearly. But overall, the comfort level is high, and maintenance is as simple as wiping off dust. I believe they significantly enhance driving safety, particularly in suburban or mountainous areas where the even light distribution greatly reduces accident risks. It would be perfect if they could be paired with adaptive dimming functionality.
