I'm considering new, low cost light options. There is a plethora (yah, now there's a word) of info here, and I have used the very nice pivot table provided in the stickied thread.

My commute is not too bad, over city streets and a stretch of dark bike path. NO high speeds or country roads.

I want to keep $$ outlay down and probably double up lights on the bar (I have an old CAteye HL500)
The Planet BIke SuperSpot (LED) and 500X/5000X (Xenon) seem fairly similar and are in my price range

HOw do the two systems (LED vs. XENON) compare?
Looks like the LED system will run longer on one charge/battery set
ARe there advantages to Xenon?

thanks!
