next time i buy a light im gona message you first with the details to see if its reputable. but i have a question for you kryptonite, like technically speaking if you have one LED module and you add another lens, wont that slightly diminish the amount of light it puts out because it has to travel through more glass (or plastic)? like idk i feel like the concept of double lens sounds really deceiving, like it might in theory penetrate more, but what would be the difference if you want the LED to have more penetrating power than dispersing power, get LEDs that have a 90 degree lens as apposed to a 120 degree.
idk if youre into astronomy or photography, but when you use something like a barlow lens or an extension on your camera lens, it changes the way the light behaves yes, but it doesnt produce more light, it usually makes the amount of light you have in the eye piece of less quality leading to pixelation in cameras or blurryness along the perimeter in telescopes. Does this make any sense to you mate?
