FAQ Luznor

Minimalist emergency luminaire, energy efficiency and avant-garde design

When the autonomy of the torch decreases significantly from its nominal value, it is necessary to replace its battery. Luznor recommends the replacement of the battery 5 years after the purchase of the torch, in order to ensure its performance at the time of use.  

It is not possible to recharge an ATEX torch in an explosion hazardous area, as the charger is not ATEX certified. Recharging must be carried out in a non-hazardous area.  

All torches of the LRX and HRX series comply with the Directive 2014/34/EU of the European Parlament and of the Council on equipment and protective systems intended for use in potentially explosive atmospheres (ATEX).

Specifically, the LRX series torches are suitable for use in ATEX zones 0, 1 and 2 (gas) and zones 20, 21 and 22 (dust) and have been certified by the Laboratorio Oficial Madariaga (LOM) with the following marking code:

Ex II 1 GD 
Ex ia IIC T4 Ga
Ex ia IIIC T85°C Da
-40°C ≤ Ta ≤ +40°C
LOM 15ATEX2183
CE 0163

The HRX series torches are suitable for use in ATEX zones 1 and 2 (gas) and zones 21 and 22 (dust) and have been certified by the LOM with the following marking code:

Ex II 2 GD 
Ex ib e IIC T2..T4 Gb
Ex tb IIIC T85°C Db
-40°C ≤ Ta ≤ +60°C (T2: lamp. 10 W – T4: lamp. 3 and 5 W)
LOM 04ATEX2129
CE 0163

In the QR, LR, HR, LRX and HRX series a number of front and rear signalling colours can be combined in both continuous and flashing mode. The signal colours can be red, amber, blue, green or white. 

There are two particular cases, the QR-3 and LR-3 torches, in which the main light can be coloured in addition to white. In the case of an RGBW main light source, this means a very different colour light emission from the signalling light, which is much more intense and focussed.

In the HS and QS series, due to the geometry of the torch, the signalling can be on the front but not on the rear, with the same range of colours as mentioned above. Cones for traffic control and other signalling functions can be used for these torches. 

Luznor has a clear customer focus and each torch or charger can be customized, either by screen printing the customer's logo, serial numbers for product control or any other text or illustration requested. 

This screen-printing consists of laser marking, the finish of which may vary depending on the colour of the housing of the torch.  

All the chargers of the C-64 series can be fitted with a part that allows the mechanical fastening of the torch to prevent any relative movement between the torch and the charger and thus ensure the charging of the torch at all time. 

In the case of the C-34 and C-73 chargers, the very design of the chargers already has a strong attachment to the torches, as they are intended for installation in vehicles and other means of transport.

Standard reference professional torches come with an instruction manual, in which all functions of the torch's push buttons are described. Visual diagrams can also be found in the catalogues of torches. 

If a torch with a standard designation has a special function, a supplement is added to the manual, in which the particularities of the torch in terms of function are indicated. Whereas, if the torch has a special designation because it is a customized development, it has its own instruction sheet. 

In case of loss of the documentation associated with your torch, do not hesitate in contacting Luznor to have it returned to you or to clarify any operational doubts. 

The access to the flashing modes on standard programmed torches is done by long pressing the left push button, starting with the torch switched off.  

Once the flashing modes have been accessed, the following cycle is repeated by short presses: S.O.S. signal, flashing, light burst, etc. To turn the torch off, a long press is required again (from any position in the cycle). 

If you have a torch with a special designation or a standard designation with special function, the flashing modes may be different from those described here. 

Access to the power modes on torches with standard programming is done by long pressing the left push button, starting with the torch switched on.  

Once the power modes have been accessed, the next cycle is repeated by short presses: low, nominal, high, etc. To turn the torch off, a long press is required again (from any position in the cycle). 

If you have a torch with a special designation or a standard designation with a special function, the power modes may be different from those described here. 

Your torch is switched off because the standard emergency function, based on an automatic switch-on for 3 minutes designed to help you locate the torch, has finished.  

If you do not want the torch to switch off after the 3 initial minutes, simply press the left button briefly and it will switch on permanently at nominal power.  

If you have a torch with a special designation or a standard designation with a special function, i.e. a customised development, please refer to the respective accompanying documents, as the automatic switch-on function may differ from the one described here. 

Your torch has entered emergency mode.  

All torches with standard reference (in catalogue) incorporate an automatic switch-on of the spotlight during 3 minutes (emergency function) as soon as the torch is removed from the charger or the power supply to the charger fails. Therefore, if the torch has not been removed from the charger and has switched on, it is indicating that the charger is no longer powered. 

Exceptionally, it may happen that the torch has lost contact with the charger due to various environmental factors such as vibrations, movement, etc. In this case, simply place the torch back on the charger and, to avoid any relative movement between them, there is an option of adding a mechanical fastening that allows the torch to be securely charged even if the charger is on a vertical wall or upside down bolted to the ceiling. 

The LED light on the top left of the torch, under the handle, is an indicator of the charge status of the torch, i.e. the current available battery capacity. 

It only lights up when the torch is either switched on or charging on the charger, and can have four levels:

  • Red: available capacity less than 20%.
  • Amber: available capacity between 20% and 60%.
  • Green: available capacity between 60% and 100%.
  • Flashing green: totally charged (100%).

Luznor chargers are specifically designed to be able to store torches for long periods of time, regardless of their charge, as they have a maintenance charging system that avoids discharging the batteries without harming them. 

Unfortunately, unlike the C-64 series, the chargers of the C-34 series are only designed for HS torches and are not compatible with QS torches. Therefore, it is necessary to purchase a C-73 series charger. 

It should be noted that if a QS torch is placed on a C-34 series charger, it will not charge (if it is fast charger it will charge, but the charging status will not be correctly indicated on the torch) but, above all, it will not damage the QS torch or any of its components. 

Yes, all chargers of the C-64 series are compatible with the QR torches, being able to adapt to the charging of Ni-Cd, Ni-MH and Li-Ion batteries in the most efficient way for each battery. 

Yes, thanks to use of a programmable microprocessor, Luznor offers the possibilty of customizing the operation of the torches. This opens up a world of options: number of flashing sequences (flashing, S.O.S. signal and light bursts as standard), number of light powers (low, nominal and high as standard), signalling colours (both front and rear), etc. It is also possible to define the push buttons and the types of presses with which to access the requested functions, as well as the order in which they should appear.  

Yes, it is possible. Luznor has developed a "LED spotlight set” that allows the simple replacement of the halogen spotlight that the HR series torches have, as long as they do not have a front signalling crown. 

In this way, the purchase of a new torch is avoided with the economic savings and the reduction of waste generation that this entitles, while the quantity and quality of the light available is considerably increased, without altering the rest of the features of the original torch.
