I think they are cost effective when I compare the price of a quality HID projectors and the time it takes to pull the headlamp assembly, put it in the oven. part it, mod the holes, reassemble and reinstall the headlamp assembly.
I'm not worried about cut off if these LED units have been designed specifically for H7/H4 applications. What I've seen when I examined the H4 assembly was that there are 2 separate Cree LED in the H4 unit that radiate for hi or lo beam.
One radiates upward in the reflector so that the light is projected in a downward direction out of the headlamp assembly. When the hi beam is activated the down facing Cree is lit, emitting light upward from the reflector.
Since this will likely behave as the H4 I would say the low beam mode will have to be switched off as it would be done with the OEM halogen H4 if you were to use the low beam.
With the wattage saving using the Cree LED there is another benefit for the FZ6 owner who is using heated grip etc.
If I can buy them at the sale price which is $59 USD each, they are certainly cost effective for me on the SV1000s. I use two H4 in my headlamp assembly.. So again if they perform as expected I think they will be a great alternative upgrade for me and others.
I hope I will have them in hand this coming weekend and I will give a report on them.
I agree the HID projectors are the best but they don't negate the idea of using a well designed LED especially if they're basically plug n play.
