Help build

Help!!
This is my first post, and i'm a beginner in this world!

I would like to build a duble P7 light, for my bycicle!

The scheme that i would like to adopt is this:

I have some doubt about:
1) the batteries link
2) the driver that i have to use. The driver should have 2 multi-level-switch.

Thanks to all!:kiss:

Welcome to CPF, xxxlucaxxx

I'll move your thread to the H&M section for you.

First off, wrong sub-forum. Reported.

Secondly, I don't know of any 10*reflectors/optics available for the P7/MC-E.

Thirdly, why the P7? It's kind of outdated tech, from an efficiency standpoint, and a small reflector that is smooth is going to produce a beam with a big donut-hole in the middle.
I would assume you're looking at the P7 because of it's mega-output. In order to be more efficient, and have a greater output, check out the XP-G triple arrays. Much less heat, and more light at a similar drive level.

The XP-G triple would cover you bases as far as a flood light goes, with a 16*optic from Cutter Electronics.

For a throw-beam, I would look at a nice-neutral white Cree XR-E. You'll get a nice beam pattern from any of the widely available optics/reflectors available, and it'll out-throw a P7 LED with similarly sized reflectors.

Yes, you'll lose output with a neutral or warm white LED, but colors will appear much more natural, and shapes much more 3-d.

interesting.... have you got a preview of the results?
have you got any web site that explane the buil step by step?
What is the driver that i have to use? and how link the batteries?
