As promised here are some beamshots of these lights before and after modifying them, photos of the mod process to follow later. I realise these pics arn't massively bright but then neither are the lights, just a reasonable/useable amount of light, plus these pics were taken on a wet night, and as you know wet black tarmac absorbs light for fun.
First up just the Spot lense with original Luxeon K2
And now the Spot lense with the new SSC P4
Both the Flood and the Spot on Original Luxeon K2's
And now both the Flood and the Spot with the new SSC P4's
And Finally a side by side Spot beam of the Luxeon K2 and the SSC P4
The Top one is the new SSC the lower is the Luxeon, notice how the SSC is a lot more floody than the K2. Looking at the first 2 pics you will see not only is the SSC a lot brighter but a lot floodier with the same lense, you see more of the fence and also the tree branch in the top right of the pic gets lit up with the SSC.
I'll post better shots on our local trails where the difference is even more apparent, and also some pics of the upgrade process.
Well worth the upgrade IMHO.
