When the N30 was being proto-typed, the L35 was also in the proto-type stage. Mtbkndad had them both. Testing at that time, showed the N30 was actually a bit brighter than the L35. IIRC, he determined that the individual bulb could possible make a difference, or manufacturing tolerances/factory adjustments to the ballast could make a difference and it might just be luck of the draw. In any case, I'm not really counting on any increase in Lumens in the L35. Even if the L35 produced a 10% increase in Lumens, the human eye will probably not see a difference. The other differences make it worth it to me. I guess we'll see when they hit the streets!
