I tested those lights, and several other versions of the same internal-ballast lamps.
If you are looking for serious LD-riding auxiliary lamps, then save your money.
When did you test those specific lights? I know you tested the 4" flood. Different animal. Different reflector, arc tube, and at this point, ballast.
Exactly correct. However, they make pretty good day running lights!jim
I would argue just the opposite. They don't make a great daytime running light because of the lamp life, only rated for 1000 hours. They are however, quite bright at night. The flood isn't a good option for on-road use.
