I have the quadratec ones as I also didn't want to break the bank so this seemed to be a good balance.
When I was installing them on my A-pillar mounts the wind blew one of them from hood height to the concrete below. Made a scratch but works perfectly fine. That impressed me a bit. Otherwise they are super bright and definitely not for street use. I use them in the mountains when going out at 2-4am on the back roads and the 4 light the entire road up.
