Ok just got in from outside and the SC60 is awesome. If your familiar with the H31 beam this is the same except brighter. The hotspot is massive and the spill is very wide and bright, my tint is white to cool white overall very good.
Even though it is bigger than the SC50 I think it is just the perfect size to use as intended with you fingers wrapped underneath the light while your thumb does the on/off UI. IMO it is perfect for EDC I like the SC50 but always feel it's weight and size is a little underwhelming.
One thing to note is a slight improvement on the UI this is the first ZL I own that will memorize the high mode. High1 or High2 you can memorize it
I have been carrying around my HDS 170T and nothing lately has seemed pleasing but the SC60 sure put a smile on my face when I took it outside. For all you 18650 fans this is a good one and like I thought it might be this is a light you can use to make a excuse for getting a couple 18650's and a charger if you have been on the fence about Li-Ion or 18650 size.
Just for reference I did ceiling bounce test with the SC60 and PD30 R4 and the SC60 was indeed slightly brighter.It comes close to my P20C2 MKII, not an easy task for a stock light with 2hr runtime
