Bike lights again

I've used the Dinotte 200L for a couple of days now. It kicked a low battery indication at me a mile from work today, on the 2nd day. This is OK, since it just strobes for 1/2 second and turns the power indicator LED from blue to red. It still kept going at full brightness. After a while (10, 15 minutes apparently) it would have strobed again and dropped into low output mode, where it would have run for 30+ minutes.

That's only about 100 minutes of runtime on 100% brightness (42 minute commutes, plus probably 15 minutes of playing with it), though to be fair to it, the batteries have been outside in the cold for 4 days and it was about 19 degrees this morning. And I had another battery pack in my bag anyway. I probably could run OK on medium power, which doubles the runtime, but I don't think I'll bother. Swapping batteries takes all of 15 seconds every 2 days.

For anyone who's looking for a nice bike light, they have a sale on these running today at www.dinottelighting.com - this light is now $100 instead of $130, and the taillight is $105 instead of $130. I just ordered the taillight - I don't like winter night riding without my strobe on the back.

[EDIT] - apparently the sales there last a couple of hours at a time. It's over. Glad I checked at 6AM.
