I just got back from my first ride using my new Fenix light (the L2D premium Q5), and I want to thank those of you here that steered me in that direction. I used one of them with the Cateye el530 I already had and the difference is what I had hoped for. Plenty of light for my needs in most circumstances (I know it's not in the retinal burner category, but retinal warmer works for me now), with enough light to fill in the areas washed out by oncoming cars and plenty to see with in the dark. The strobe works great too, the traffic signs really light up with that in the twilight. I also liked the way the strobe got the attention of the otherwise oblivious dogwalkers - they could ignore the constant light but not the strobe. I went down the MUP I usually ride home on, and the lights were on at a ballfield as I approached. They went out when I was riding in their light, and my lights put out enough light so that didn't make any difference in my ability to see where I was going. I'm impressed!

The light seems to be be well made too - no loose ends, bad threads or anything. Thanks again for the recommendations.
