Daniel your the watts man explain that.

15 watts is what it consumes. It has the same brightness of a 125w incandescent bulb.

Incandescent bulbs use electricity to heat the wire till its white hot.

Less than 10% of the energy is radiated as visible light.

Led lights use magic to do with quantum gaps electron levels etc that produce photons of light directly. It's a very high efficiency process. Can be over 80%. So one watt into an incandescent system makes a very small bucket of photons and a lot of heat.

One watt into an Led produces over 8 times as many photons and very little heat.

Has anyone found an easy way to tap into the 36v of the Oxydrive system? I really wish there was an output port somewhere. The USB one on the battery is handy I guess but I would rather have a light socket, I hate having to strap my bangood pack to the frame and I have forgotton to do it once, which made me have to return home after 8 miles into my commute which made me late for work and angered me no end!
You would have to splice the battery wires inside the controller compartment, then drill a hole in the cover to bring the wires out.
Thats what I hadn't hoped for. Do you know if the electronics are swimming in mastic on the OD kit? I know that some controllers are well sealed!
The controller pcb is cast in jelly, but IIRC, the terminals or wires on the back of the battery connector are accessable.
My light arrived today and the size and light out put is pretty well neat. The lighting functions are very good the left hand button for the front bezel in flashing mode is proabably enough in town to be seen at night without using the right button for more options OR yes there is more, press both buttons together and you get a very intense very bright pulsing light which is blinding.

Neat? Is that all you can say? Look at the title of the thread!

Neat in my terms = Pretty damn good which may along similar lines as the title.

Had another play tonight and you only need to long press the right button to get the blinding intense super bright pulsing light. Although it doesn't light the way the glitzy flashing bezel was certainly very noticeable when I was riding home from work tonight also had the handle bar indicators on tonight as well.

hi all received light package yesterday, charged and tried in garden,

its more powerfull than my cree 900 lumen torch.

however no instructions , and there seems no way of turning the light completely off when not in use?

 

can only get rear green light as least power consumption.

seems I have to disconnect power lead from light?

 

thanks all

It's called double pole isolation.

Which light do you have? The one in post #1 can be switched on and off except the lighting of the on/off switches.

One of my bugbears, a green light as soon as you conect the battery ( unless it's red signifying low power)

I thought why have a 7.4v 2s battery, the inboard led driver steps it down anywho, I brought some new drivers that run straight from 3.7-4.2 volts n messing about balancing cells and no need to disconnect the battery between rides :cool:

I can't see the supplied battery pack giving enough current. Even if it could, it wouldn't last long. I think it would be better with a 6 or 8 cell pack.
i have 4 Panasonic 3400ma grade a cells it will last for hrs ive tested it ;)

 

if i run my light on max and run the cells down to 2.5v it will go for ten hrs the pack is 8.4v. light and 5v 2000ma usb.

ill wack it up to 12v if i need to ;)

 

I think that DC-DC (Buck) converter is not any use to you here.

 

Higher voltage is also not what you need here it's the current capacity of the batteries, that looks like a big boy light. So physically it will be more batteries in the pack.

I found that a simple way to prevent handlebar mounted lights moving around is to fit them UNDER the bar rather than on top of it.

the pack i have does put out 8.4v so should work with the light ok mine gets a bit hot when i was testing it why i used a fan to cool it down.

 

if thats not bright enough then i dont know what is for 15 quid.;)
