I have 2 of these Nova's. Are Pricey. I would sell one of them. They do offer great light for working outdoors. Lights everything up. I was hoping for more throw from them to have a better spot further ahead. The switch takes some getting used to and I think the 5 levels are too much. 3 would be better. Headband is a bit small and their plug is big and bulky. Not sure of run time yet as I have been using different batteries, but can run off one 3 volt lithium cell. Not sure if their boost circuit drives the lamp to the upper range of its specs or not, or how effecient it is.
I really like the light ouput, the lightness and is wellbuilt. Waiting to see how it works in the cold.
