What separates the Sprinter from any other headlamp on the market? It has rechargeable battery that is built into the headlamp. No extra batteries to take out and charge. Simply pop the proprietary charging adapter on to the battery pack, plug it and let the charging begin. We know that we have some viewers/readers that live outside the US and the good news is that the charging kit includes not only a standard US plug, but 3 foreign adapters that snap onto body of the wall plug to fit your need.
On the back of the headlamp you will find a safety light embedded in the battery pack. While this flashing red light is great for running in areas of high traffic, it may not always be needed so we were glad to see that you have the option to disable it.
Since we can’t just throw in some fresh batteries and start using the unit, we took the chance to charge and discharge this lamp a few times. Performing this exercise gave us a better feel for how long it takes to charge fully and then how long we could run it before looking for the outlet. What we discovered in 4 discharge/charge sessions was that once the lamp was completely drained it took between 4-5 hours to fully charge. Once fully charged we were able to get 7-8 hours of continuous output on high beam before the light rapidly dropped in light output. These charging/discharging tests were performed in the climate controlled Trail Trials indoor lab so outside temperature, humidity, and other factors will probably cause a little more strain on the batteries resulting in shorter burn times.
Other Features of Note
Black Diamond put some thought into the design of this unit. It’s very lightweight. The entire assembly feels almost not there when wearing it on your head, which is a good thing! The headband is well designed with a “compartment” that the cord that runs from the battery pack to the light travels though and keeps it from dangling and potentially getting snagged on something.
- Lightweight – 3.5 ounces (100 grams)
- Rechargeable – fewer batteries to throw away
- Brightness to weight ratio is good
- Well thought out headband with top stability strap and wire compartment
- Red blinking safety light on the back that can be turned off
- Rechargeable – tough to recharge on the trail
- Has proprietary charging attachment
- Only 7 hour burn time on full brightness
Black Diamond touts this as a “streets-to-trail” headlamp. Without even knowing that prior to the review that is the same conclusion we arrived at, so in that aspect, they nailed it. This is not the lamp you are going to use to get you through a 100 miler. It is, however, a headlamp you can trust to be bright enough and have the juice needed to get you through your week day runs when you get home after the sun has already set.
