Dual SSC P4 Mountain Bike Light System


This is my first LED project. I am a bit of a machinist so I put together some nice litte housings and came up with this design.

Here's the parts used

2 – SSC P4's from DealExtreme
1 – 850mA voltage regulator from DealExtreme
2- P4 round Optics from ledspot.com - 1 tight spot – 1 oval
1- Canon BP-945 Li-ion 6000mAh battery 7.4v with modded charger holder
1- connector ( acts as switch )

Basically I will keep this brief since you have already read a lot of these reviews.

The P4 was glued with Arctic Aluminua (AA) to the aluminum cap I made. This acts as the heatsink. The optic sticks right over the LED and onto the cap. The tube slides over that and the pivot bracket scew pinches the tail cap in the tube. There is an o-ring there to seal it up. I'm not good at turning threads. I used packing tape over the optics as a protective layer. The screw has 2 o-rings pinched between the bracket to provide some resistance and allow positioning adjustments on the trail.


The BP-945 Li-ion battery should last around 6 hours without a problem. I modded the charger to allow me to plug into the battery without having to mess with the contacts and circuitry.


The beam shots are in Papago Park, AZ. The oval provides a broad view of the technical stuff right in front of me and the spot shows me where I am going. I kept a decent pace on the trails even a 10pm with these lights. The housings hit steady state around 110 degF. The shots don't quite do it justice, because the depth preception isn't there, but you are seeing about 50ft of gravel there. I am happy.

I also rode with my Rayovac High Beam P4 mod headlamp which provided a great combo with these lights. Check out my other post for the High Beam P4 mod pics.

Hi, Excellent job.

Are enought voltage with 7,4v to 2 leds?? I think that you need more voltage to supply 2 leds.

Greetings - Saludos
