Some Other Features Of ODM Headlamps
Regulated output
Regulated ODM headlamps provide a constant brightness level throughout the life of the batteries rather than gradually decreasing as the batteries drain. This is a feature that is good and well-liked.
The drawback: At the point when batteries are depleted, the radiance of a directed ODM headlamp can go dim suddenly. In the dark, this could leave you scrambling to change the batteries. On an unregulated headlamp, the dimming light is an early sign that the batteries are about to run out of power.
Red-light mode is available on many ODM headlamps. Red light is suitable for use at night because it does not shrink our pupils like white light can.
Resistance to water All headlamps sold at REI can withstand snow and rain to some degree. They are also able to withstand minor jolts and falls.)A few are able to tolerate brief, superficial immersion.
Tilt Having the headlamp unit tilt up and down is a nice feature. The beam can be positioned precisely where you want it. When reading with a headlamp, this comes in especially handy.
On/off switches If you’re looking at headlamps in a store, try the buttons to see if you like how they change modes (from high to low or the other way around). Additionally, some switches lock to prevent accidentally activating the headlamp within a pack.
Batteries Because lithium batteries perform better in cold conditions than alkaline batteries, headlamps that are made to work with lithium batteries are a good choice for use in cold weather.
Nickel metal hydride (NiMH) rechargeable batteries also perform well in cold conditions and work well with headlamps.
A few high-power ODM headlamps that utilize four batteries position the battery pack on the back of the headband and run a little link from the pack to the headlamp. Although it reduces pressure on your forehead, it can be cumbersome. On some models, top straps that can be removed provide stability.
