Ok, they arrived today and I installed them after work. Quick and easy, actually appear to be very high quality with the electronics separate from the bulb assembly itself so it keeps it more compact. The fan is actually near silent and the bulbs showed no quirks.
Went for a ride after dark and I was quite impressed. Nice crisp white light and things a LONG way ahead of me were lit up well. Road signs and anything with the reflective material on them lit up like a christmas tree, as did the eyes of at least one roadside critter I passed. High beam didn't have as much effect as I would have expected, but I think it has to do with the fact that stuff that a halogen would have lit up on high beam, well...it was kinda already lit up on low beam with the LED.
I followed a friend on his Spyder across Highway 2 through a dark area and he reported no annoying glare in his mirrors, but he said "you are sure visible though". I call that a positive.
Pictures don't really do it justice.
Top of a hill with about easily 3/4 of a KM of road ahead lit up. As mentioned, anything reflective lights up like a Christmas tree. The telephone post visible on the left side of the lane about 3/4 of the way down the hill was probably about a good 300-400m from where I was parked.
Backroad. There's actually a car parked about 3/4KM ahead of where I was stopped on the shoulder and you can see it lit up somewhat by my headlight.
This one doesn't look great as the road actually crested downwards a little where the light cuts off but It does show how nicely it lights up the sides of the lanes as well, or in this case, the ditch.
For basically $25/Bulb, I'm happy with this one.
Not once during an hour out riding, including passing a lot of oncoming cars on dark roads, did anyone flash their high beams at me to suggest I was blinding them, so I consider that a good thing as well.
I will do some more testing.
