  1. Ever since I had a battery failure on the 2017 Trans Baviaans the topic of bicycle lights started to interest me. An electrical engineer by trade - I figured that this cannot be as complicated and expensive as the market seems to suggest. Over the last 4 years (on and off) I have tested the good, the cheap and the ugly when it comes to batteries for endurance riding. My findings have led me to build my own prototype and yesterday I finally came to testing it with known parameters. For the first test, I have used the Extreme Lights Endurance light which seems to be most used light for the rides that I have mentioned above. My test setup includes a GoPro with sequence shooting at 60 second intervals within clear view of my G-Shock which was used for timing. Extreme Lights claim 40+ hours' run time at the 200 Lumen setting when used with their 5200mAh battery - I am using the same Lumen setting but my battery is designed to produce 6800mAh at the same voltage. My test is 24 hours in and things are looking good thus far - I will keep posting on this thread for anyone that is interested. After the test is completed I will share some findings which may or may not be informative/trivial.
  2. Hi Hubbers It is seldom that one comes across an on line dealer which not only backs the prodcucts it sell, but also goes the extra mile when it comes to delivering on promises. Andre from K.Man is just such a dealer. I had a problem with a T- 04 light supplied by K.Man. I emailed Andre , who immediately responded to my query. I got no excuses , if buts or maybes. Andre made an arrangement to deliver a replacement battery to my home at an agreed time ON A PUBLIC HOLIDAY. I receievd my battery on time and as promised. If anyone is considering purchasing a bike light , I have no hesitation in recomending Andre and K.Man lights. Regards Gavin Smith
