Lumens - OK is that RAW or EFFECTIVE.
I can attest to the Truck-Lite having a very precise intense beam. Very little scatter. This in my Guzzi.
And since that comparison - things have advanced a bit
The R3 on twin JWS Adaptives is a fair bit brighter overall - but even so does NOT have that intense core on Dip. Beats the living daylights out of the Truck-Lite at night for overall riding. Plus of course there is the additional curve beam set.
Dip and fogs - Ah well Now that is something else again
Take a look at the Album here to see how well Cheap Chinese lights fare. They too are BRIGHT but are poorly focused.
