FAQ

Headlamps

What is Lumen?

Lumen describes the total amount of light that a light source generates.
The light is measured in all directions from the light source, by inserting the lamp in a sphere and measuring the total light inside the sphere. Therefor it doesn’t tell you how much light there is in a specific direction. Silva declares the lumen of the whole lamp.

What is LUX?

Lux describes how much light there is on a surface. The light is measured by illuminating a sensor which tells you the amount of light reflecting from a surface. This can be translated into how long the light will reach. Silva measure the lux at a distance of 2m.

The combination of how much lumen there is and the lux level can describe how the light distribution looks like. High lumen and low lux would translate into lots of light close to you and not so much light in the distance. And the opposite with low lumen and high lux would mean almost no light close to you and more light in the distance.

What does IPX class mean?

The IPX class tells how resistant to water, or moisture, the unit in question is. There are 9 different classes each represented by a number, the classes are IPX0 to IPX9.

0 is no protection and 9 is the maximum protection (Protected against close-range high pressure, high temperature spray downs)
All Silva products are made with an IPX classification between 4 and 7.
For further information of your products IPX requirement please review http://silva.se/all-gear

My lamp heats up quickly and then the light output goes down, is this a fault?

The LED:s used in today’s headlamps are very strong and emit a lot of heat when used, to counter this and to cool the LED:s most of the lamp unit is made in aluminum to allow the lamp to be able to make use of the air current that follow from the movement. When the light is used without proper cooling the LED:s will dim down due to the heat, if you use the lamp outside it will work as it should. A small loss of light output can be expected in situations where the cooling factor is not optimal.

Can I exchange the LED:s on my headlamp for stronger ones?

The LED:s used in Silva lampas are not removable, neither should you open the lamp unit since this will void the warranty

My lamp wears the batteries in a pack mounted on the headband but in cool temperatures the burn time is reduced, why is this?

The reason the we do not recommend that you use lamps with batteries mounted on the headband in cold weather is due to the fact that normal Alkaline batteries does not perform well in temperatures below 1 degrees Celsius. The batteries are unable to provide the specified amount of power output in lower temperatures but Lithium batteries can be used to improve the performance. If you know that the lamp will be used in cold weather, for skiing or similar activities, we suggest that you purchase a lamp that has an external battery pack, that can be worn inside a jacket or similar, or one that has a rechargeable Li-Ion battery since this can cope with much lower temperatures that Alkaline batteries.

How many charge cycles can my Li-Ion battery handle?

Between 400-1200 cycles.

What type of warranty is my headlamp sold with?

The warranty is 2 year against production- and material faults. If the headlamp is sold with a rechargeable battery then this is covered by a 6 month long warranty since this has to be taken care of to maintain its performance. Make sure to have the battery charged at 50% if you store it for longer periods of time (1-3 months) as this minimize the power drainage of the cells preventing them from being damaged. If you store the battery for longer than 3 months you cycle it, discharge it fully and recharge it to 50% every 3 months. A NimH battery needs to be stored fully charged and recharged every 2 months since it has a much higher power self-drainage than the more modern Li-ion versions.

My lamp (Runner, Pavé, Trail Speed elite) started to blink for 2 seconds when I was running, and then it repeated this again after a few seconds. Why did it do this?

This is the battery warning, it signals that the battery is down to 20% and you should start thinking about the time left on your run.

Battery flexibility

For flexible use, most SILVA batteries and headlamps are compatible. See below to check compatibility for your battery/lamp:

The following lamps can use the 2,5 Ah (art. no. 57109-20)and the 6,6 Ah (art. no. 57109-70) rechargeable Li-ion batteries: X-trail, X-trail plus, all versions of the Sprint, Alpha (2,4 and 6), Runner, Pavé, Trail Speed, Trail Speed Elite, Power trail and the Cross Trail 2. The battery warning on the Alpha lamp will not function with these batteries.

Compasses

What is magnetic North pole?

It´s the point on the surface of Earth’s Northern Hemisphere at which the planet’s magnetic field points vertically downwards. The magnetic North pole is in continuously movement. The Magnetic North Pole is the point that traditional magnetic compasses point toward.

What is the geographical North?

“Geographical North” is also called “True North” and is the direction from any point on Earth toward North Pole.

What is inclination?

A compass will react to the Earth´s magnetic field and the compass needle will tilt (vertical direction) downward or upward depending where you are location on Earth. It means that the needle will always be parallel to the Earth´s magnetic field.
inclination

What is Deviation?

The difference between True North (geographic North) and Magnetic North.
Magnetic deviation will occur in some places of the world, often caused by high amounts of metallic ore in the ground. This will cause the needle to divert either west or east and the deviation varies between 1 and several degrees depending on the amount of material that influence the needle at the place where you are. Most maps will have a note regarding the local magnetic deviation and on how to calibrate for it. Many of Silva’s compasses have a function to compensate for the deviation; this is very useful for avoiding mistakes.

Our balancing zones

All Silva compasses are balanced in three different zones:
MN (Magnetic North)
ME (Magnetic Equator)
MS (Magnetic South)
BALANCING ZONES SILVA

Can I use my compass in any part of the world?

No, all Silva compasses are weighed for one of three magnetic zones and using your compass in the “wrong” zone will cause the needle to tilt and may result in it getting stuck against the roof/floor of the capsule and showing an incorrect north.

Does Silva make a compass that can be used all over the world?

No, Silva Sweden does not have a compass equipped with a so called global needle.

My compass has turned 180 degrees and now north is south and vice versa, can this be remedied?

The reason that the compass is not showing north is most likely due to it being subjected to a magnetic field that has polarized the needle. This is, unfortunately, fairly common in today’s world since we carry a lot of items that emit a magnetic field such as mobile phones, GPS and other equipment. A compass needle cannot change its own polarization; it has to be “forced” to reverse its polarity by a magnetic field.

We write in the manual that it is very important to check the compass every time it is used since polarizations does happen, it is as important as checking any part of your survival gear before it is used, since your life may very well depend on its functions.

It is not complicated to reverse the polarization of the needle but to be 100% sure of the result you should be using a controlled magnetic field. Because of this we do not recommend that you polarize your compass by yourself.

ADC

My ADC displays altitude in a very random way, it goes up and down over time even when I am not moving. Why is this happening?

It is important to know that an ADC calculates altitude by using the atmospheric pressure; it does not contain a GPS that obtains a 3-dimensional position from satellites. This will in turn lead to a change in altitude every time a change in weather occurs and therefore it is very important to have several locations, along the route that you travel, with known altitude so you can calibrate your offset value to get an accurate altitude reading.

What is wind chill?

The wind chill factor is the effect that wind will have on your skin, i.e. the way that it feels colder when the wind is blowing making the temperature feel like it is lower than it actually is. The wind chill factor is only in effect when the temperature is below 5 degrees Celsius, if the temperature is above this the wind chill will not affect the temperature and thus the current temperature will be displayed in the wind chill display.

Is it possible to obtain a new battery lid for my ADC?

Yes, you can order one from your nearest Silva agent using article number 55253-801.

Is my ADC waterproof?

The ADC is not waterproof but it can be under water for a short period of time and therefore it can be used by, for example, kayakers. As long as you do not put the ADC in the water for a longer period of time the seal to the battery compartment will hold tight.
