Hello,
I just thought I'd show my new light setup which looks to be very good for the amount of money invested. It consists of:
(2) MTE 5-mode P-7s modded to run on external power
(6) 18650 Trustfire 2500mAh protected batteries in parallel
(2) Fenix light mounts superglued on the 90 degree position
(1) Viewpoint spacebar
Also anderson power pole connectors and wiring for the connection.
Beamshots coming soon, I haven't really aimed it properly or anything yet either and the battery pack needs to be dressed up abit.
Ride Impressions:
I took the bike out for a quick 25km ride that covered many lighting conditions. First the ride started at my home out in the country with potholed roads and very dark. The lights worked great here, I ran both lights on high just to really get the best look at the potholes and cracks in the road. Throw was not a problem at all, I could see very far ahead so 25 km/h was just like during the day. After about 10km I got to a new area lit with streetlights periodically, this was a hard test but with both lights on high I was able to push through that light and still have useable light. Then I pulled into a MUP that is surrounded by trees/bush, wow, this is where a floody light dominates! I could see everything, everything. I pulled it back to just one light and was still seeing everything I could possibly need. And then for a little I got to ride some smooth, straight roads so I went one light high and one medium, this grants the most uniform beam when the high is aimed up more.
Conclusion: Very happy

The light output is great (I've had cars overtake me and my lights were not being washed out at all), the beam is great with one aimed low and one at medium range and the flexibility of 2 lights lets you find the ideal setup for almost all scenarios.
Let me know what you think.
