Tungsten Open Face lights are workhorses in the industry. Like a par light, it delivers more output than its same wattage fresnel counterpart.  They are amazing for bouncing, projecting through diffusion, and using them for ceiling bounces for room tone. 

I use them for distant houses in the background of wide shots to give depth to windows, bounce them into the ceilings, or project out of windows onto steps or driveways.  They have a flood and spot function.  They do not project good hard shadows.  Because of the bulb and reflector, you usually get 3 shadows with your cut. My favorites are the Arri 750-watt HPL or the Arri 2K HPL.
