Some tips with regards to buying based on sellers' pictures alone, on how to pick a throwy flashlight.
A large reflector is a good indication that the light will throw nicely. If all else is the same (same LED outputting same # of lumens), the larger the reflector outside diameter is, the less divergent the light beam will be.
More powerful LEDs often have a higher surface area. This is like comparing a single-mode diode to a multimode one. The end result is more overall "power," but also a harder to collimate beam.
Drive current is important, and cannot be guessed based on pictures. Unless they give a high resolution pic of the driver. And even then, usually you can't tell the current that the LED is driven at.
Lastly, reviews are important, but keep in mind that some of the reviews will be by folks whose other flashlight is an old maglite solitaire keychain incan. A candle probably has more candlepower than the ol' solitaire :can:
