The Finnex fixture is a quality one, the Fugeray has less light then the Fugeray2.
LEDs should last 40000-50000 hours if they are good. Lower quality ones will go out or use cheap LEDs. Also never really go by the wattage with LEDs, they use much less energy so yeah.
If you are into DIY you can make an LED fixture your self with Cree LEDs. They are mega bright, I have a flashlight that uses one and it is crazy bright. Though you do need to know a bit about electronics.
