I believe the technology for LED conversion kits are just a little behind compared to new vehicles with stock LED headlights. That being said, for whats on the market right now, I am satisfied with my purchase. I purchased a new 2018 Honda Civic EX-L Sedan, which comes with low beam projector headlights with H11 halogen bulbs. Why Honda is behind the curve in LED technology for some of the cars is a mystery. Keeping in mind they have been putting LED headlights in the Acuras for years and are just recently offering LED headlights on some of their "top of the line" models. I ordered these H11 LED bulbs with same day shipping and installed them later that night. Installation took less that 5 minutes. Simple plug and play. Although the LED bulbs are a bit larger in the back because of the heat sink and fan, there was enough space between the other components in the engine compartment. No modifications were needed for my car. As far as the comparison between the stock halogen bulbs... The halogen bulbs did "throw" the light further, and were probably a bit brighter, but the LEDS have a more even-distribution of light from left to right. Obviously the LEDS are a stark white with a very slight blueish tint compared to the depressing yellow of the halogen. But now my low beam lights actually match the stock LED accent / day time running lights on the sides of the headlights. I have had some OPT7 led conversion LEDs on a previous car. The cougar motor lights are definitely cheaper and the fans on the bulbs are much more quiet (almost silent) than the OPT7s. As far as the intensity of the light between the two LED conversion kits, I wasn't able to do a side by side comparison, but to my memory, the light output is probably about the same. I did have to replace the OPT7 lights a number of times because one of sides of the bulb literally melted. This was an ongoing problem that I was never able to pinpoint a cause for. One thought was that the climate was too hot (Tucson Arizona, where the summers get up in the 100's.. so who knows how hot it was under the hood of a black car) and another thought was the subwoofer system I had in my trunk was causing rapid voltage changes to the LED. Now the test will be to see how the Cougar Motor LEDs hold up as far as life-span. In summary, the Cougar Motor LEDs do the job and I am happy with them.
