Any light is better than no light. And with half-a-large, you could buy dozens to try.

Bear in mind, that just as there is no one best bike, there is no one best light. Every one is a compromise in some way or another. Find the one or two that compromise in a way that works for you, and just go for it. Then forget about what everyone else says about the light(s) you chose.

Next year, there'll be a dozen "better" ones to give you buyer's remorse. We're just in a period of rapid technological improvement WRT bike lights. I don't see it stabilizing for a couple of years, maybe five or more.

For the record, I started out with a cheapie, and graduated that autumn to a NiteRider halogen (that hasn't been made in years). For several years thereafter, I bought better lights every year. Last year and the year before are the first two years I didn't purchase new lights.

This year, it was new dynamo lights for the primary commuter, then I moved the old dyno lights to the backup commuter and bought a dyno hub for it.
