If weight and price are key considerations for you, then the Black Diamond Gizmo may be just the ticket. It's not bright, but has a low price and great battery life. If this doesn't make it into your climbing pack, consider one for the glove box of your car. It stands just behind the similarly priced and Best Buy winning Petzl Tikkina. The Tikkina is a better trail finding headlamp and is brighter. The Gizmo has a better close proximity beam and is 25 percent lighter. So for $20, depending on your needs, the Gizmo may actually be the best headlamp value for you.
