I've used a number of NiteRider lights on my helmets (and bars) over the years.
For a helmet light, I would advise against the Pro 2200 Race. You don't want to be messing with a separate battery with a helmet light. Get a light with an internal battery.
With regard to the Lumina 1200 MX, I don't have experience with the stick-on mount. NiteRider sells a Lumina helmet mount that uses straps ($15) and works well with typical helmets. They are easy to adjust the beam up and down while you're riding. Mount them right at the very top of your helmet so they don't droop forward.
One bit of advice - don't shop using maximum lumen output. Those run times are too short. Look at the lower settings and check the run times and lumen output to see if they work for your type of riding.
