I got an SC50w as well. Overall, it's a great, super compact, well built and powerful light but I agree with some of the points made here.
I also feel the tint is a tad too yellow. I wish it had the same tint as my H501w which is about perfect, imo, tint-wise. (Btw, my H501w does have the new UI with the two stage low, which I like.)
Back to the SC50w, mine activates in my jeans pocket unless I lock it out, but as mentioned above, that's very easy with this light. Can be locked out with just a fraction of a turn, maybe even less than an 1/8th.
Aside from the too yellow tint, my biggest disappointment with the SC50w is the beam. While I can see it might be perfect for some, I feel the hotspot is too tight and the spill is too weak and wide. I would prefer a slightly bigger, less intense hot spot (even though this would provide less throw) and a slightly tighter brighter spill. In other words, I wish the beam overall was a bit more evenly floody, instead of the super tight bright hot spot with the huge weak spill. If the spill was about 10% tighter and brighter, even at the cost of some of the intensity of the hot spot, I think it would be much improved.
But the build quality and heat sinking on my SC50w is awesome and I love the super compact size, the good runtimes, the side clicky and the UI is pretty good once you get used to it. It's nice and bright on high, especially with 14500's and the two stage medium and low are nice.
If you are happy with the beam, it's a great choice.
