I own both. The Professional's Favorite 20 Million Plus Candlepower spotlight throws significantly farther than the Stanley HID, and has a much more focused beam. In recent tests, I have verified that the Pro's Favorite 20+MCP is able to visibly illuminate very distant trees out of the Stanley HID's visible throwing range.
I will take some photos of the two lights together tomorrow for size comparisons.
BTW, this thread might need to be moved to the Spotlights and HID flashlights forum.
