Backpacking headlamp



I am in the process of designing a ultralight backpacking head lamp which will weigh 1.5 oz including batteries. It will have basic features in order to save weight and will not be as rugged as others. I am asking you what are some of your preferences of headlamp features are and if you think this could be a valid product. This will help me in the design of my product. So thanks to all that reply. If you would like to find more details about the product contact me at j.timmons4498@gmail.com
