This is where things get difficult. I would offer a full kit, but as this is just a prototype run. It is difficult for me to carry ALL costs. There will be (many) more production runs, soon.

ok, i am in as long as the unit has the B flex driver and power switch, if it came with a clamp, would be great as ur link points to a round clamp. battery pack i will sort out later


ok, coffee has kicked in i am up to speed on the bracket, lol, please include it if possible

Is there any mechanical problem (e.g. structural or waterproofing) with using the shell with no electronics (i.e. no bflex)? There would be 3 wires (ground plus one power wire for each led cluster) going into the rear cable conduit, and the controller would be in a box with the battery. I'm still thinking of using an Arduino board and the idea is to control the clusters independently. Also, is it mechanically feasible to install the clusters with some adjustability (maybe using shims) to how they are aimed? Again the idea is to have high and low beams.

The 25C lipo pack actually scares me. A momentary short is much likelier to cause a fire than something like that happening with the laptop pack, which has lower-current cells and which has various forms of protection built into the pack. The lower-current cells also have more energy density, though some of the space/weight savings is taken back by the extra circuitry in the pack.

i know little about voltage, but this battery is 5000mah and waaaaaayyyyy cheaper

I was planning on using a single 22.2v lipo pack and using velcro to attach it to the underside of the stem. The pack size is quite small.

That's a 7.4 volt pack so you'd need 3 of them. The price is actually suspiciously low, making me suspect low quality cells. The 6 cell version is here:

same packs as the e bay listing but 1/3 rd of the price.

i was shown those packs by some radio controlled car enthusiasts, they use them pretty hard and say they are *good* packs.

I am interested. Let me know when they are ready. I would also like to see some beamshots. Thanks---JPHIII.

The 25C lipo pack actually scares me.

1. Nope, it can be used as a shell. Put candy in it if you want a waterproof container

2. Yes, but you would have to remove the Glass and use shims under the leds. (and remove waterproofing quality) A more feasible option is to use carlco's 'eliptical' optic 10510


3. So does any other lipo/lion pack you are using now. Most don't have short circuit prevention.

hmm, sans electronics....happy to cough with electronics mathew, battery pack i can get from hobby king around the $75 mark

Once prototype units get delivered. I will be reviewing everything, including the possibility of offering a kit (sans battery and charger)

 

[sosemot728]

Talked to the manufacturer. Prototype units will be ready and delivered by the 14th

 

[daveymoff38]

I'd be interested. For 150 AUD? That's really cheap for something with that kind of output. I've just laid out £70 on Niteriders new 400 lumen minewt lamps. They light up the roads and trails really well. Don't think I've seen anything over 1500 lumen.

Keep in mind, this is sans electronics and LED's (you will have to source your own)

After this prototype run is completed, I will be organizing a larger production run and examining the possibility of including everything.

 

[sosemot728]

Pototypes are in the mail (got delayed slightly) and will be delivered to me on the 17th

Using two bflex drivers defeats the purpose of having small dimensions. 3S2P would increase lumen/watt efficiency, but would reduce overall light output. https://www.candlepowerforums.com/threads/257955

Why not use a boost driver? Maybe you could run 3s2p with this driver http://www.dealextreme.com/details.dx/sku.26106 and modify the sense resistor as shown here:

https://www.candlepowerforums.com/posts/3271128&postcount=46

With one you could push at least 550ma to each XPG (possibly more with a more aggressive reduction in the sense resistor), and also use a lower voltage supply in 5-7v range. Or you could run two of them in parallel and have two independent 3s configs at >1a per die. Could power with 5 or 6 Nimh D's. Or for simplicity a bunch of parallel Magcharger Nimh sticks.

or stick with name brand HQ driver and use one hyperboost ($40 vs. $4 for DX driver)

still a newb, just noodling. sorry if i'm clogging up your thread. free bump!

Built up pics..., beamshots?

PP sent for one... sorry to see that uptake has been so slow since it looks like a REALLY nice design. As you know, my own interest is in hosting a DIY-programmed controller, but I think most users basically want finished lights.
