Some other factors to consider when choosing a headlamp are the type. Headlamps come in two basic form factors: L-shaped and T-shaped. L-shaped headlamps have a single reflector or optic mounted at a 90-degree angle to the battery tube like the Olight Perun 2, and Sofirn SP40. This design often features a magnetic tailcap for added versatility and can be used as a worklight, flashlight, or headlamp. L-shaped headlamps usually have higher output and more throw, but at the expense of size and weight. The other type is the T-shaped headlamp. This type positions the reflector or optic in front of the battery tube. The Cyansky HS6R is an example. This configuration allows for more natural light distribution since the light is being projected directly in front of the user, rather than off to the side like an L-shaped headlamp. These headlamps tend to be more compact and lightweight, but can still provide very good output.
