Flash Diffuser - Lambency. A lambency flash diffuser is a device that fits onto the front of a flash and both reflects and diffuses the light output, reducing greatly shadows. The flash unit is pointed vertically, and the device fitted, light hits the curved top cap of the unit and this reflects it back through the side.
Depending on the grill brand, diffusers might also be called heat deflectors, heat distributors, flame tamers, burner shields, heat plates, vaporizers, or even flavorizer bars. Whatever the name, diffusers perform 3 important functions to make barbecuing better. 1  They distribute heat evenly across the entire grilling grid, preventing hot and cold spots. 2  They create a barrier to protect the burner from dripping grease, food juices, acidic marinades, and sugary sauces.
