I haven't posted in quite some time. I've been playing with my new SC600 today, and my impression is that it is the most amazing flashlight I've ever used. This flashlight addresses my needs almost perfectly with a palm-sized body, clean floody high, and a super low low, a silent switch, and it appears to be pretty rugged. It took me quite some time to overcome my reluctance to use a non-standard battery (18650), vs. AA, but I'm a convert now.
My last "non-walmart" flashlight was/is an O-light T25 2 AA flashlight that I thought was the coolest thing since the mini-mag-light. I did a test today with 4 little flashlights. An original mini mag-lite with incandescent bulb, a mini mag-light I upgraded with an LED, the O-light T25, and the SC600. The old ones seemed so good and I used mine daily for years, but the difference is just astounding. The SC600 can light up a room like a real lightbulb, and light up a house or tree 30 yards away almost like a floodlight.
You guys here are the cutting edge, and while my SC600 is probably on the lame-end of what new LED's can do, it's just perfect for me, and I just wanted to thank you all for keeping the manufacturers on their toes and progressing the state of the art. I could easily see replacing all of my interior bulbs with LED's in the next few years.
That's about it. Just amazed again.
