These were gifts from a good friend. Previously, I had not owned nor used Inova lights. I don't know what the nominal nor measured outputs happen to be. Those figures are not important to me.
What I value from these products is their usefulness in the event that I need light in a circumstance involving the use of my automobile such as map reading, changing a flat tire, or looking for object lost in the dreary depths of my glove compartment, trunk, underneath the seats, or between the seats and center console.
They remain nestled in a soft nylon case from countycomm and in my glove compartment with a box of SF123 next to it.
I have read on this BB as well as on EDCF that Inova will be upgrading these products to the more efficient, higher output LED.
The build quality is exemplary and I am happy with these products.
