I was looking in the specifications for the reflector size and it's not listed. Generally the reflector size will provide the largest variation in throw for these different spot lights. It also stated that it comes with a 50W and a 20W bulb in the specs, but in the description is shows the addition of a 100W bulb. Maybe that's an option though.
Overall it's fairly generic and uses the same technology that's been available for the last 12 years...12V 7amp battery with a 100W automotive bulb. It will certainly outperform any 6V lantern or any D cell flashlight but I wouldn't consider them to provide any extraordinary beam or great run-time, especially with a 100W bulb. How much does this light cost anyway?
What will you be using the light for?
How far would you like, or do you need the light to throw?
Have you considered any HID lights yet? The N30 is impossible to beat at its price point.
P.S. most 100W incan automotive bulbs which are run off of that SLA battery in front of a 7" reflector, will throw well to about 350 yards or about a 1/5 of a mile. The "1 mile beam" description at the top is complete sillyness.
According the the box size, this reflector appears to be in the 100mm to 125mm size range and will throw noticeably less than a 7" reflector.
