Those torch lights that you had shown in your links are fine. The key is how to diffuse the light. Cause these torch lights tend to be too concentrated or spot, which essentially gives you the same "caught-in-headlights" kind of look on your subjects as direct camera flash. Many methods you can use to diffuse the light, eg. use a portable mini flash diffuser, pass the light through a piece of translucent white paper, bounce the light off a wall/ceiling where available, bounce the light off a portable reflector etc etc....
