I own both the Lumina 450 and the Lumina 350. You would think there would be a slight difference in brightness seeing that the lumens increase but having tested both after fully charging them, in a dark room. I almost feel like the 350 is brighter. Not sure if I got a defect or if it's all a marketing gimmick... Either way, plenty of light for your average night time riding in the city and likely enough for the suburbs as well. Battery is not bad for the amount of brightness. One thing that occurs a lot is that you will need to 34;reset34; the light every other ride as it will not turn on. Simply hold the power button for like 10 seconds and then you're good to go. If the Lumina 350 is cheaper, stick to the 350.

Light works great nice and bright only down side I can find is that the charge cable that comes with the light is the only one that I have that works not a huge deal but still worth mentioning.
