The mains mode lumen output for all Thorlux luminaires can be found on the product datasheet. At present, for output in emergency mode, please contact the Thorlux Lighting Design department.

All Thorlux luminaires feature a white test label which contains the product part number, the date of manufacture, and the manufacturing order number. This label provides all the information required to either re-order more of a product or receive support from our technical support team. When contacting support via the website or email, attaching a picture of this label, if possible, will ensure that the support representative is best able to resolve your query.

An LED driver is a self-contained power supply which regulates the power to an LED array. LED drivers convert mains voltage alternating current (AC) to a direct current (DC) supply. They ensure the power supply is constant and uninterrupted by compensating for changes in the temperature and electrical conductivity of the LEDs. This prevents the LEDs from overheating, flickering, being susceptible to unwanted colour changes and degraded performance. LED drivers usually have a range for the output current; this allows for one driver to potentially be used in several different applications. When replacing an LED driver in a Thorlux luminaire, please contact the Technical Helpline to ensure the driver's current output is set correctly.

ATEX hazardous areas are defined as having a potentially explosive atmosphere present. Different areas are classified using a zone rating system, with a single-digit code for gas and a two-digit code for dust. A Zone 0/20 area is one where an explosive atmosphere is present in normal circumstances, Zone 1/21 where it is likely an explosive atmosphere could be present during normal circumstances for only limited time periods or when selected tasks take place and Zone 2/22 where an explosive atmosphere is only present in abnormal circumstances, such as a fault condition.

Thorlux offers several Type ‘n’ products suitable for use in Zones 2 & 22. Details of which can be found in the hazardous area section of our website. The ATEX rating for each hazardous area product can be found on the product web page, datasheet, and installation leaflet. Further to the ATEX rating, the installation leaflets also contain the conditions of use and the Declaration of Conformity, listing applicable standards.

Under the ATEX regulations, Thorlux cannot specify suitability for use of any particular product, as this will depend on the concentration and ignition temperature of the gas or dust, the mounting location of the luminaire, and other factors. An assessment of the location and the approval of a luminaire for use in a hazardous area can only be made by a suitably qualified CompEx engineer. Further information on explosive atmospheres can be found on the HSE website.

Non-dimming luminaires are the most basic option manufactured by Thorlux. If the luminaire is not illuminating, it is highly likely to be one of the following: an electrical supply not being present, the luminaire’s integral fuse having operated, an LED driver failure, or mechanical/electrical damage to the LED Printed Circuit Board (PCB). First, confirm the circuit is energised and check the integral fuse (if present on your luminaire type). If the problem persists, contact the Technical Helpline for support with replacement parts.

Thorlux luminaires feature premium drivers utilising flicker-free technology to ensure there is no perceivable flicker. If a luminaire develops a flicker or intermittent flash, this is most likely due to a component-level failure in the LED driver, causing the output to become unstable. In this case, the LED driver will need to be replaced. This can also result from an intermittent connection to the LED PCB caused by a damaged connector. In this scenario, it would flash on when contact is made and off when contact is broken. In either case, contact the Technical Helpline for support with replacement parts.

Thorlux no longer manufactures luminaires that support 1-10 V dimming. With the move to LED-based lighting systems, manufacturers of control gear have moved away from basic analogue dimming controls in favour of more advanced digital control systems, such as DALI. These digital systems offer more precision and control with dimming, plus many other features not present on analogue systems.

DALI (Digital Addressable Lighting Interface) is a type of digital control signal that connects luminaires to a control device. In its simplest form, DALI can be used to dim or switch luminaires. However, with the correct equipment, DALI systems can also send a variety of more complex commands, including checking the functional health of the connected luminaire.

Most Thorlux luminaires are available with DALI control gear; for compatibility, please see the relevant product datasheet or contact Thorlux Technical Helpline.

The most common reasons are: electrical supply not being present, operation of the integral fuse, an LED driver failure, or damage to the LED Printed Circuit Board (PCB). First, confirm the circuit is energised and check the fuse. Removal of the DALI control wires should cause the luminaire to illuminate to 100%. Failure to illuminate indicates an issue with the control gear. If the issue remains unresolved, contact the Thorlux Technical Helpline for support.

DALI luminaires are controlled using a simple two-wire control bus, which is connected to each luminaire and control system in parallel. Loss of control of a group of luminaires is typical of a wiring continuity fault; loss of control of an individual luminaire is likely to be a driver fault. If further assistance is required, contact the Technical Helpline.

Thorlux offers two DALI control options. The most basic is the Eco Touch, offering five levels of dimming and on/off control. It can control up to 25 DALI drivers. The Eco-Touch does not require commissioning to operate. Two-way switching is not possible as the system is limited to one Eco Touch per lighting circuit.

The other option is the more advanced Eco Sport. Offering more precise control with 1% dimming intervals, three user-customisable pre-set light levels in addition to Off and control of up to 120 DALI drivers. An LCD indicates the current output level. Eco Sport also supports the connection of additional manual switches.

Platform 1 allows luminaires to be linked wirelessly in groups for presence detection and scene control. Energy usage and luminaire health data can be downloaded via infrared from each luminaire using a SmartScan Programmer. Emergency luminaires will self-test, and operational status can be retrieved using a SmartScan programmer.

Platform 2 adds a SmartScan Gateway. The Gateway communicates with all connected luminaires to retrieve operational data and the health status, which can then be accessed securely by authorised users via the SmartScan website. It is also possible to enable email alerts. Further information can be found on the SmartScan section of the Thorlux website.

Any site personnel can become authorised SmartScan users with the site owner's permission. To add/remove or make other changes to authorised users for a SmartScan site, contact the Thorlux Site Services department.

This indicates that the SmartScan Gateway has been unable to communicate with the luminaire. The most common cause is that the luminaire was not powered at the time of upload. If the luminaire is powered and illuminated, contact the Technical Helpline for support.

The LED driver in the luminaire is reporting an output fault, which can be caused by a faulty LED PCB or connector, as well as a faulty LED driver itself. Contact the Thorlux Technical Helpline for further support and replacement components.

This indicates that the LED driver or emergency module is not responding to the SmartScan system when queried on its status. The most common cause for this is component failure. Contact the Thorlux Technical Helpline for further support and replacement components.

This indicates that the SmartScan emergency luminaire has failed its monthly function test and will need further diagnosis. A new battery and/or emergency module may be required. Contact the Thorlux Technical Helpline for further support and replacement components.

A handheld SmartScan programmer is required to commission a new or replacement SmartScan luminaire into a network. These are available for purchase, but most customers opt to include a commissioning visit on the lighting quotation. A Thorlux engineer will commission all luminaires to the customer’s requirements, ensure the site is working correctly and thus yield the highest possible energy efficiency for the installation. For support with using the SmartScan programmer, contact the Thorlux Technical Helpline.

This indicates that the SmartScan emergency luminaire has failed its annual duration test. A new battery and/or emergency module may be required. Contact the Technical Helpline for further support; replacement batteries can be ordered via the Thorlux Sales Office.

An integral emergency luminaire contains an integral battery that powers the luminaire in the event of a mains failure, to deliver a low light level to act as either anti-panic or escape emergency lighting. Either manual testing or an automatic test system is required to test monthly and annually, to ensure the full duration (normally 3 hours) is achievable, and the luminaire is serviceable.

A centrally supplied luminaire does not contain integral batteries; it is supplied from a dedicated battery bank within the building. This type of system is known as a Central Power System (CPS). This is usually housed in a dedicated room or enclosure, and special care is required with its use and installation. Thorlux can manufacture luminaires for central power applications. Speak to your local Thorlux sales engineer for details.

Emergency lighting is designed to prevent panic or to illuminate escape routes. Therefore, it is better suited to luminaires used for general illumination or dedicated non-maintained emergency luminaires intended for such applications. However, some luminaires may not have an emergency option due to thermal constraints. Thorlux product ranges primarily intended for display and accent illumination are unlikely to have emergency options.

Emergency luminaires (Thorlux prefix E) require a person to manually perform both a monthly function and an annual duration test. Each luminaire must be observed during the test to confirm that it is working correctly.

AutoTest luminaires (Thorlux prefix T) will automatically perform their monthly function and annual duration tests at randomly set times. These luminaires indicate their status by the colour of their indicator LED. Each luminaire will need to be inspected at monthly intervals to identify any failures.

SmartScan Emergency luminaires (Thorlux prefix W) will automatically perform their monthly function and annual duration tests. For SmartScan Platform 2 users, a full record of the testing history, along with luminaire health status, will be available through the SmartScan website. The SmartScan website can also be used to schedule testing times, allowing the user to select a time that will cause the least disruption.

On Self-Test and DALI emergency luminaires, the indicator will turn red to indicate a fault. A slow red flash, one second on/off, indicates a battery failure. A rapid red flash indicates a fault with the emergency module. Finally, a solid red indicator LED indicates a lamp or light source fault. If the LED indicates a fault, contact the Thorlux Technical Helpline for assistance.

A non-maintained luminaire will only illuminate when the mains supply is interrupted. It will remain lit until the battery is discharged (typically this will be a three-hour duration), or until the supply is restored. Otherwise, it appears as off, despite being powered continuously. This is normal for exit sign-type luminaires in some buildings.

A maintained luminaire will be illuminated as a normal luminaire would be when the switched supply is present. If the unswitched supply is interrupted, it will continue to operate in emergency mode at a reduced output until the battery is discharged, for a three-hour duration, or the supply is restored.

Thorlux luminaires have a five-year return-to-base warranty on all products supplied. However, Thorlux can offer free-of-charge replacement parts for a competent person to change on-site. Please contact the Thorlux Technical Helpline for further information (contact details at the top of the page). The luminaire part number and nature of the fault will be required.

All return to base warranty repairs are handled through the Thorlux Sales office (01527 583222).

Batteries are generally classed as consumable items, and as such are supplied as free from material defect at the point at which they are dispatched from our premises, and are excluded from our warranty.

SmartScan emergency luminaires are typically supplied with a five-year battery warranty, as indicated on our datasheets. In the case of failure within this period, please contact our Technical Helpline.

Note that certain dedicated emergency luminaires with Lithium Iron Phosphate (LiFePO₄) batteries are subject to an extended ten-year warranty. Please refer to product documentation for further information.
