How effective are lensless LED headlights?

Lensless LED headlights are not as effective as well-matched LED dual-beam projectors. Here are specific details about LED headlights: 1. Light Pattern: If the original vehicle lacks projectors, LED headlights without low beams will not have a built-in cutoff function, resulting in a light pattern without clear cutoff lines. If the original vehicle has no projectors but you desire a light pattern with distinct cutoff lines, you must install LED bulbs with a built-in cutoff function for low beams. 2. Color Temperature: Common color temperatures for LED headlights (listed in order of frequency of use) are 6000K pure white, 3000K golden yellow, and 4300K yellow-white. During rainy or foggy conditions, yellow or golden light must be used; white or yellow-white light should not be used. Therefore, in such weather, you can use the original halogen bulbs or LED yellow/golden lights, but not xenon lights, as xenon lights do not produce yellow light. 3. Current: The power of LED headlights is typically around 30W, with a current of approximately 2.2A. 4. Durability: The temperature of LED headlight bulbs ranges between 70-90 degrees Celsius. The higher the temperature, the faster the light decay and the shorter the lifespan. However, LED bulbs are significantly more durable than original halogen bulbs.
I remember driving a car with lens-free LED headlights last year, and the overall feeling was that the light was somewhat scattered, not very concentrated. Driving on the highway at night, the illumination range was quite wide, but the central point wasn’t bright enough, especially when turning, the visibility wasn’t very clear. The advantage is that its structure is simple, cost-effective, and much easier to modify—you can install it yourself. The downside is obvious: in rainy or foggy conditions, the penetration is poor, as the light gets scattered by moisture and appears weak. Compared to LED headlights with lenses, the brightness and precision are noticeably inferior. After using it for over a month, my conclusion is that it’s sufficient for daily city commuting, but for long-distance night drives or bad weather, the risks are higher. If upgrading the lighting system, I’d recommend prioritizing the lens version—it’s more reliable and worry-free.
As a car enthusiast, I've studied the technical features of lensless LED headlights. By eliminating the lens component and relying directly on LED arrays for illumination, they offer lower costs and better heat dissipation. In terms of light performance, the distribution is more uniform with consistent edge brightness, but the poor central focus results in less distinct light spots. During use, I found that modification parts are abundant and easy to handle, with lower power consumption. The downside is that the light penetration is weaker than versions with lenses, which can be quite troublesome in mountainous areas or rainy weather. Overall, it's a mid-range option suitable for beginners or modification enthusiasts, but not the best choice for those pursuing high-performance lighting. I'd say, from a technical perspective, this thing balances price and basic performance—whether it's worth buying depends on your usage scenario.
