Woo hoo! My Arc SLS (First Run #293) arrived one day early. I checked UPS tracking before work this morning, and I was delighted to see that the delivery date had been moved up. Sure enough, it was waiting on my porch (fortunately, I live in a safe neighborhood) when I got home tonight.
I'll try to avoid 'preaching to the choir' and just say it's one fantastic little light. The 'flaws' are minor cosmetic ones. Besides the slight difference in tint of the anodizing between the head and battery barrels, there's a tiny nick in the knurling on the head and a bit of anodizing rubbed off next the O-ring of the single AA tube (hidden in use).
The important part - the beam, looks great. Perfectly centered and not at all objectionably green.
Didn't have any 123's around, but I did have an unused 223 camera battery laying around. Tore off the plastic case and, voila 2-123's to feed to the SLS. With the 123, this looks to be the hot set-up.
Yep, here's one more happy SLS owner. Thanks Peter!
