The MC-E is AWESOME, my only complaint is it's abit of a yellow tint but there is a WG Tint showing which might be whiter I'll have to check the colour codes for them, puts loads of light out, good range would like slightly better focused but you see EVERYTHING, going back to what i was using is just a joke also, P7 was leant out which would help also though.
Your eyes adapt to more light, so sadly diminishing returns and forever chasing a dream, but think it'll get me through a year or so.
Tried a 2nd light on my head, raised the spot just slightly making it PERFECT, but more weight than I like
Run time, the P7 ran out at the same time so must be 75mins area, as expected the max amperage the batterys can give out.
