I have not tried this product, but I have been researching and experimenting with alternative lighting for a few years. This product is 6000k, which is that blue-tinged hue that makes me want to brush my teeth after one goes by me. I see no claims on the product to DOT compliance or being legal for street use. That implies to me that these are just another flavor of harsh, scattered light. If you can find what certificates it meets, please post them. Otherwise I'll assume they are not street legal.
I've tried about everything out there that claims to plug-n-play LED and HID bulbs into existing headlight reflector/lenses, and quite frankly, whether you're the driver or the hapless victim of these Micky Mouse conversions, they suck.
Non DOT LEDs are not designed for traditional headlight assemblies. The light source isn't placed correctly to properly focus the beam, so the light scatters and you become "that guy" burning out the eyes of oncoming traffic. You can't aim them low enough to coexist with traffic without lowering them so much you have no light downrange. The light looks better than incandescent from behind the bulb, yes. But the first time you ride in rain or fog you'll see the scatter and appreciate how unfocused it is. All of the DOT conversions I've seen are an assembly, including the bulb, projector, and ballast.
6000k, as I mentioned earlier is blue, not white. It distorts color and changes contrast to the point that you lose 3-dimensional vision. I couldn't distinguish a patched pothole from an actual pothole. Since I don't have the option of avoiding road hazards with tricycle gear, it's important for me to know what it is on the road ahead. 6000k doesn't do it for me. I prefer 4500k, which is closer to daylight. Also, I have seen studies that conclude that the combined effects of color and contrast abberations cause more rider fatigue.
LED is indeed cooler at the light end than incandescent. But it is hotter at the back end. They generate so much heat that many include heat sinks or fans to operate. It's enough heat to melt the plastic bits of an unvented housing.
Finally, most LED makers flat lie about the power draw and brightness of their products. Read carefully. Are the claims per bulb, or per set? To make a product look better than the competition, they might claim 30w of power. Is that the output figure or the total draw including line drivers and fan? Is it describing the bulb or a pair of bulbs? It's a real shock to open the box and discover your 30w powerhouse is two 15w bulbs with an additional 10w each of overhead.
The bottom line for me is that these are useless in the real world and deceptively marketed. If you want to truly improve your lights, get proper HID projector housings and do a proper conversion.
I did. I made a centering disc to mount a 2.5", 35w, 4500k bulb in my main bucket. I added the same in 55w for driving lights. The projectors do hi/low. I have all three controlled with my dimmer switch. I own the night without being a hazard to oncoming traffic.
Cue the flames.
