That looks like good competition.
The run time shown is not enough for my commute.
MY Li-Ion battery gives me about full run time in the winter in Rhode Island. I have not used it below about 10 degrees F. It just has not been any colder when I was riding. The insulation on a water bottle battery can have an effect too.
Even alkaline batteries that really work bad in the cold will work fine if you keep them warm. I've done it in the past by putting the battery pack under my clothing while riding. 98.6 is great for batteries. Any type of battery can be made to work this way.
There is an owner report somewhere in these forums for both of the inexpensive batteryspace.coM HID lights. I don't remember if they mention the cold. Search the forums.
$100 lights are entry level lights.
