I joined just to make this post! I've been lurking off and on for years.
I bought and received an SC600 mkII a couple weeks ago. In the past few years I've become more concerned with self-defense, and in the past few months I decided I wanted to carry a flashlight. The SC600 is my first "real" flashlight. The build quality, the feel of the switch, the compactness -- all outstanding. And it's insanely bright, as expected.
But there's one thing I don't like about it: color. I get green tint around the hotspot and a purple discoloration around the outer perimeter of the spill. In turbo mode, the discoloration is less noticeable and I would characterize the color as cool white. I get this on all settings, including turbo.
Regardless of whether I like its color (and I don't), I don't plan to send it back. It's my first EDC and I'm pretty happy with it. It's just nutso to be able to walk into my backyard and see, well, everything when I hit the button. My middle son (age 6) has discovered without any influence from me that he likes flashlights too, and he takes one of my Dorcy Cool Blue #1's to bed so he can read with it. (Yes, he's six and he reads in bed with a flashlight. Pretty cool huh?) But he loves it when I shine the SC600 on the ceiling of his room so he can compare it to the paucity of light coming from the Cool Blue. We then chant "Hefty hefty hefty! Wimpy wimpy wimpy!" together and laugh. He doesn't even know where that comes from but he likes to say it. Ah, good times with flashlights.
Welcome to the forum and thanks for sharing your story! As a father of three I spend a good deal of time playing flashlight games with my kids as well.
Regarding your experience with the tint on the Sc600Mkii mine is exactly the same. I love everything about this light except the tint. It seems all my Zebralights with XML emitters have had the nasty green hotspot with purple rings. My XPG Zebralights have beautiful tints. All this being said I am very happy with my Sc600Mkii. It is a great light, but I do hope the XML2 will improve the tint quality.
