Nice one "OldEssexMan",
I am pleased you found them as good as I do..
No screaming fans and dont they just feel a quality item..
Its one of those rare cases where you actually do have your cake and eat it..
Better light output BUT with a much lower current draw...
Our bikes have pretty powerful alternators but on other bikes I have owned, they had a much lower output.
My last bike had a 420 watt alternator, so the saving made a difference.. Free heated grips in that bikes case.
