SPECTRA BY SILVA

Get the most out of your Spectra

Spectra by Silva is the result of high level engineering. There are certain key factors that will affect how your headlamp will perform in terms of the amount of light, and also for how long. When you know how it all works, you will know more about your Spectra

DEVELOPED TOGETHER WITH THE EXTREME

The battery that comes with the Spectra headlamp has been put to the test by orienteers in the Swedish Orienteering Federation. Their speed is ruthless off the beaten path, even in darkness. They go all in from start to finish, and use the maximum light output for up to two hours. These athletes depend on their products to perform on the same extreme high level as they do. There is no room for doubt when you are the best orienteering athletes in the world.

IT IS JUST AS SMOOTH FOR YOU AS FOR WORLD CHAMPIONSHIPS MEDALISTS

Thebatteries that are included with Silva’s headlamps are made of cells that areput together in different formations. The Spectra battery consists of eightloose cells, combined on a row, which makes the battery slim and smooth to runwith. Use the Spectra Vest to keep the battery in place, regardless if you runfor gold or if you run the trails for QOMs on Strava. The vest is also a greataccessory for enduro, snowmobiling, skiing or biking.

HOW LONG WILL THE LIGHT LAST FOR?

How long the light will last for depends on the light mode you choose and the temperature where you are at. If you carry the battery unprotected from the cold when you are riding your snowmobile in -20 degrees Celsius, you can count on an hour of maximum light. If you choose a lesser light output for your bike ride, and the outside temperature is 20 degrees Celsius, the light will last for about three hours when using the same battery.


BURN TIME – THE SHORT EXPLANATION

We use the American national standard for lighting systems, ANSI, to measure burn time. What burn time actually measures, is the time it takes from when the light is turned on until the light reaches 10% of the start value. A headlamp with 1000 lumen, and three hours burn time, will give you 100 lumen after three hours, according to ANSI.

Note that burn time is not a static number. It is affected by different factors:

• If you use the maximum or minimum light output
• The size of the battery
• The temperature in your environment
• Speed and wind, because the headlamp needs to cool down to perform

DUAL CONNECTION DOUBLES YOUR BURN TIME

Your Spectra headlamp comes with a Dual Connection, which gives you maximum light for a longer period of time. The Dual Connection enables you to have two batteries connected to your headlamp, thus double the burn time. We didn’t make any compromises when developing this headlamp, then neither should you.

USAGE & SAFETY

Get the know how of your Spectra, then give it all you’ve got. This is a headlamp that loves speed, just like you.

AUTOMATIC DIMMING

Headlamps with extreme light will get very hot, that is why they depend on wind speed to cool down. The headlamp will automatically dim down the light if the wind is insufficient. This is the headlamp’s automatic safety system to prevent overheating. The lower light will give you the benefit of an increased battery burn time, because you are not using the full effect of your headlamp.

If it is cold outside, or if the headwind is strong, you will enjoy the maximum amount of light. This also means a shorter burn time, because the stronger the light the more battery power is needed.

BE SMART WITH YOUR HEADLAMP

A smart way to optimize light output and burn time, is to always adjust the amount of light depending on your actual needs. If you are going up the mountain on skiis, you will rarely need 10 000 lumen. Spectra has four different light modes, choose between the lower light modes when going slowly uphill. Increase the light output when you ski down the mountain, this is the perfect time for full light. The wind from the speed will make sure the headlamp delivers all its 10 000 lumen for you.

If you use your Spectra in 20 degrees Celsius, or even warmer, the headlamp will not deliver 10 000 lumen if you are standing still. It needs cooling to perform, and you need speed for the feeling of adrenaline. This is why Spectra is a headlamp for action sports!

FULL CONTROL OF THE BATTERY LEVEL

The battery has five diodes that show the level of remaining battery capacity. Just turn on the headlamp and the diodes will light up for 20 seconds. You can also check battery levels using your Spectra remote control. This is clever when the battery is mounted on your bike or kept in the vest on your back. Go all in on your sport, without doubting how long the light will last for.

Note that if the battery gets cold, its capacity will be lowered. Therefore, make sure you carry the battery close to your body or in a backpack, especially if it’s cold outside. A cold battery might lower the capacity by 10-30%. Be smart with it.

SAFE STORAGE

If you want to store your Spectra for a longer period of time, we recommend that the battery is 30% charged. This is optimal for a healthy battery storage, both when it comes to safety and the slow discharge that always occur in lithium batteries over time.

Be aware that the battery should be kept away from environments that might reach 60 degrees of Celsius and higher. Therefore, never keep batteries in a car on a hot summer’s day.
