What is the difference between a regular 1 Watt luxeon and a 1 Watt Gallium Nitrate ?

Gallium nitride is the material the LED die (light-emitting region) is formulated with.
Virtually all LEDs in true green, blue-green, blue, violet, UV, and white have gallium nitride dice. This would include Luxeons, "UFO LEDs", 3mm, 5mm, 8mm, 10mm LEDs, and SMD LEDs.
One type of white and one type of blue LED has a die formulated from zinc selenide, but the rest are gallium nitride.
