Re: I\'m Going Into This Flashaholic thing Head First!
The Newbie mod will be brighter (the HID mod is about 175 watt incandescent, while an overdriven Newbie would be 200-300, my best guess, but check with the source).
Runtime for HID, at 35 watts, or about 45 with ballast losses is about 2 hours. I have to say, that's very useful.
Eh, get both!
