After quite a lot of reading up on this forum, I think that the SC51 sounds like my ideal light! I really can't think of anything I would change, apart from maybe (in an ideal world) making parts user replaceable. But, the question remains - should I go for the cool or warm version? Does the warm version offer any practical advantages, apart from the 'nicer' colour? Is a case of although the light is slightly dimmer, it's easier to pick things out with a colour temperature closer to daylight?
The main use it will see is an EDC, where usability is more important than absolute brightness (as typically I'm never far from a source of 1-2000 lumens), but there is part of me that likes the 'wow factor' of a bright light in a small package! If anybody could come up with some side by side beamshots of the two different SC51 versions (I'm slightly leaning towards the SC51w at the moment) that would be most helpful.
