thysmeades Posted July 29, 2009 Author Posted July 29, 2009 This a beam shot of a mate who has one in the UK. Exactly the same as mine. He has 6 narrow optics! hows this for a beaut beam!! image removed thysmeades2009-07-31 08:58:21
scuzzy Posted July 29, 2009 Posted July 29, 2009 One question, I see you have tapered handlebars. Any "bright" ideas on how to avoid it slipping down once you hit the rocky downhill parts? Great, great light, WELL DONE!
AndreZA Posted July 29, 2009 Posted July 29, 2009 goodness, what a nice even spread of the beam. I doubt you need anything more then that. As long as it can burn for 6 hours at that intensity.
thysmeades Posted July 29, 2009 Author Posted July 29, 2009 With the batteries you are running' date=' what is the burn time ?[/quote']i am currently running a very small battery pack made up of 4 x 18650 cells.14.4v 2500mA li-ions. On full power, projected time is 3 hrs but I have only had two rides so am not sure actually. Will update you guys soon after testing. On the lower power settings, it lasts up to 25 hrs.thysmeades2009-07-29 07:55:20

[/quote'] It will, if I build a 14.4 V 5000mA battery, which is quite possible and easy to do. remember, this little puppy is pulling 21V at full power!

[/quote'] you thought you had me there hey!The lights will come with this electron bracket (http://www.chainreactioncycles.com/Models.aspx?ModelID=6091), the one in the pic is specifically for a 27mm bar and is a makeshift one till CRC have stock and I can order.BTW, I have two very bumpy rides with this light already and there was no movement. Probably because it's so light, about 80-90 grams or something like that?!
AndreZA Posted July 29, 2009 Posted July 29, 2009 Another tricky request (maybe), the battery must not be in a bottle. Maybe in a Tri-bag on the top tube?Mampara2009-07-29 08:16:52
thysmeades Posted July 29, 2009 Author Posted July 29, 2009 Another tricky request (maybe)' date=' the battery must not be in a bottle. Maybe in a Tri-bag on the top tube?[/quote'] yip, it will come in a neoprene bag which can be velcro'd to the top tube or stem. It's homemade, but looks ok. i will post pics and have all the details ready before I start selling these lights. you guys can then choose to buy or not once you have all the facts. Other cool features are:Thermal dimming if it gets too hot, user configurable.med, low and very low voltage warning via a status LED5 levels or 2 levels, depending on setupStrobe with all levels as welletc etc etc

Help.Me. Posted July 29, 2009 Posted July 29, 2009 This a beam shot of a mate who has one in the UK. Exactly the same as mine. He has 6 narrow optics! hows this for a beaut beam!! what is the distance to the car +- ?

So even though you run a 14.4 v battery, your leds are drawing 21Volts. Power in watts is the current x voltageP = 500ma x 21P = 10.5W hope this helps.Tthysmeades2009-07-30 07:42:49
supertorro Posted July 30, 2009 Posted July 30, 2009 sjoe: that is a seriously nice piece of work. did my own housing and so on ,but seeing how slick yours is, I'm just going to hide mine and not show anyone
