1.)Is it can emit a white beam in night?
The 3800 i believe uses a Xenon filled 100w bulb. I haven't used the 3800 but i'm guessing the color comparible to a 100w car xenon headlight. The xenon gas will allow for a whiter "hotter" color than regular halogen bulbs. I have the 55W version which is listed at 1 million candlepower, it is pretty yellow compared to my Surefire E2, but VERY VERY Bright.
2.)Is the focus is perfect, or have any dark spots?
The FOCUS isn't perfect, meaning the hotspot isn't a perfect circle. It's kinda rectangular to say the least. But there are no dark spots at all, other than a VERY VERY tight center beam, the fall-off light is pretty consistant. Kind of like a REALLY SUPER bright Maglight at it's tightest focus, but without a round beam
3.)Is it can illuminates over 1 mile?
I have no official answer for this for i have never needed to light something up a mile away. BUT i might have come damned close! I once illuminated the opposite side of a small lake which was about 500 yards away. I lit up a geyser in Yellowstone National Park while i was on top of the Balcony of the Old Faithful Inn about 800 yards from Old Faithful. I tell you, i recieved MANY MANY thanks for the aid of light that night. It was a moonless night at about 11:30pm. Memorable experience? YES!!!
4.)Is it can easy to carry?
NO. After long periods of time this thing get very annoying to carry. EVEN with a neck strap. Its very BULKY, and heavy. The 6" reflector is like carrying a 6.5" subwoofer speaker driver around. But is it worth it? I think so, especially for a Flashaholic on a camping trip with the only highpowered torch!
