Also recieved my SC600w today from Zebralight. Has the w and 5 min. stepdown, though not a big deal. I could not be happier with the tint. Creamy without a hint of green on any level. What did surprise me though is how much darker the finish is compared to my SC600. Easy way to tell them appart I guess though I don't see myself using the 600 that much now. Have been running mine on LG 2800 batteries without problems.
