I just bought what seems to be the newest model of the Black&Decker V2 Million Power Series rechargeable spotlight (from Home Depot), and I am extremely impressed by it. It uses a 12V SLA battery and a 35W/55W dual filament H3 halogen bulb with a sliding switch on top to toggle between high beam (55W) and low beam (35W).
It seems to be the best pistol grip style thrower I have ever held, and can light up objects over 600 yards away with ease. It has a very concentrated pencil beam with a scorching hotspot right in the middle. I can't believe just how bright this thing is for only 55 watts, and how it out throws some of my 100W halogen spotlights.
Here are some pictures:

Now the Power On Board HID for comparison. Notice how extremely close the Black&Decker is in both coronal and hotspot brightness!
The new Black&Decker spotlight has a built in AC charger, and a green light that blinks when it is full. I have experienced very good runtime with this light so far. I really like the style and feel of the light, and highly recommend this light to anyone in need of an extremely powerful spotlight. My friend bought one of these recently on my recommendation, and he is equally blown away by it and happy with it in all ways.
