Actually, the depth of the reflector has more impact on how much throw there is. Visualize the following: The way an LED is constructed light leaves the surface in almost a complete half sphere, more some if the LED is domed. A wide reflector lets more of those rays of light proceed unreflected, resulting in a wider spill. As a reflector deepens, it intercepts more of those rays and aligns them into the main center beam. The deeper the reflector, the narrower the beam, with the corresponding spill amount decreasing both in intensity and in angle.
A good example of this is the Nitecore P30. Its max output at Turbo is only 1,000 lumens, yet it is able to put 95,500cd into the main beam, for a throw of 615m. These numbers are the stated results as per the ANSI/NEMA FL1 specification. The candela number is probably pretty accurate, but in terms of usefulness, the range is probably closer to 400m. The P30 accomplishes this by using a very deep reflector. The head is only 50mm wide, but the reflector is close to 70mm deep. At high output levels, there is a very definite bright narrow beam out the front.
To get back to the original question, some of the zoomie lights attempt to do just that, allow the user to select exactly how much spill and throw is presented. Other lights, like the TM16 attempt this by using four emitters in relatively shallow reflectors. The increased lumen output from four emitters extends the throw, while the shallow reflectors allow more spill.
