Just picked these up. Was originally going to just get the 3800 lumen but they were out at the time I ordered.
First off, cyclops is a great company to work with. Had some shipping problems that were entirely my fault and they fixed them immediately and had the bulbs out to me in less than a week.
To start, yes I paid $150 for headlight bulbs. Yes you do need two if you want to update both your headlights.
The ballast and extra parts were a bit bigger than I had originally imagined and seen in photos. When I started to install, I wasn't sure all that stuff would fit in the bucket. With the right squirming around of everything, they do go together. I did have to cut a bit of the rubber boot to make it wider to fit the bulbs fan but aside from that, no modification required. Plug and play.
Old low beam halogen.

As you guys can see, a much brighter, whiter, and more beam in the same type of pattern from the reflectors. Haven't had a chance to ride in the dark yet as it's not dark where I am and probably won't for a while as I'm in Minnesota and our spring is now some areas entire winter.
Just thought I'd share and say that for the moment, I'm extremely impressed with the company and the product.
