Got my Nichia one in today. Not bad. No battery? No biggie. Not sure why they give you a case when the thing comes sealed to prevent patina. At least there's extra o rings. For the price, it's a decent light.
MetalBeardThey're already preinstalled on the light. The other rings in the box are spares for later when they age and break down through the years.
But to install, I normally just remove the old one and put the old one on by placing it on top and sliding it down over the threads.
