Frequently Asked Questions

Why do I need to register?

To benefit from the full functionality of the website you will need to register your details with us. This will allow you to obtain more detailed specifications about Display Lighting products and allow you to create wish lists that can be converted into quotations at the click of a button. Display Lighting will send regular updates on new developments about upcoming product launches and events to people who register their interest. 

How do I use the new Display Lighting website?

The new website has been designed to take the headaches out of creating lighting specifications. The team at Display Lighting have spent the best part of a year updating information about each product and presenting it in such a way that is concise and simple to compile. Bespoke products, such as; Spectrum, Tubelight, Quantum and DisplayLED, can be constructed in such a way that the end result will be an exact fit for your retail and exhibition displays. The first step is to register your details and your interest by completing a simple form and once it has been submitted you can begin to compile your wish list. Below the details of each luminaire you can find associated and compatible products that Display Lighting would recommend for use with that fitting such as lamps, transformers, LED drivers and lamp accessories. Once you have compiled your wish list, simply click the "Submit Wish List" button and a competitive quotation will be prepared and returned to you.

Constant Current or Constant Voltage?

All of the Display Lighting LED products shown on this site will state if they should be operated with either Constant Current or Constant Voltage drivers.

As a rule of thumb, products that operate on a 12V DC supply should be operated on a constant voltage LED driver and "wired in parallel" (as with halogen lamps and transformers) and products operating from 350mA, 700mA, 1200mA etc. supplies should be operated on a "constant current LED driver" and "wired in series".

Please check the individual data sheets supplied with the products for wiring diagrams.

Which LED driver do I order to operate LED Spotlights?

If you are ordering any of the Spectrum LED spotlights then an LED driver is required, we offer drivers to operate single spotlights or to operate various numbers of spotlights depending upon your configuration.  To calculate which driver is most suitable for your particular application the first thing you will need to know is the  "forward voltage" of each of the spotlights that you are using (the forward voltage of the Spectrum range of spotlights is 3.6V). The next thing you should check is the output voltage range of the LED driver (the LED/350-10 LED) constant current driver has an output voltage range of between 2V and 29V). Once you have established these two figures you simply need to divide the output voltage of the LED driver by the forward voltage of the spotlight and this will tell you how many spotlights the LED driver will safely operate (29V / 3.6V = 8) so the LED/350-10 LED driver will operate between 1 and 8 Spectrum Spotlights.

What is DisplayLED?

DisplayLED is a very slim, circular aluminium profile (diameter 15mm) that is available with multiple fixing options that allow horizontal or vertical fixing with beam angle adjustment. DisplayLED incorporates a built in very high density SMD LED strip for uniform illumination with 120 high bright LEDs (10W or 20W per metre). Each LED outputs 4000mcd. The design consists of an easy to clean dustproof OPAL acrylic diffuser that is available with different opacities and the whole system operates from a 12V DC power supply. The luminaires can be supplied with either cool white, neutral white or warm white LEDs emitting a 60 degree beam. It can be manufactured up to 2000mm in length.

What are LED strips?

LED "strips" can be supplied in either rigid or flexible versions, the latter tending to be the most popular choice recently due to the ease of installation and reliability. A rigid LED strip is a long thin printed circuit board that is populated with a number of LEDs, they are normaly offered in 300mm lengths that can be plugged together end to end to form a constant line of illumination. A flexible LED strip is a flexible PCB ribbon, again, that has differing quantities of LEDs mounted equidistant along its length but the ribbon strips are generally supplied in reels of up to 5m making them much more cost effective.

There are many types and brands of LED strips flooding the UK market from China and a buyer has to be vary wary that he or she is purchasing a quality product. Display Lighting is very careful to specify that the LED chips and components assembled on all of it's LED products are from a highly trusted and well known manufacturer.

Why use retrofit LED lamps?

LED lamps are the perfect lighting solution for jewellery, china watches and diamond displays particularly within showcases and display cabinets. All LED lamps generate heat (there is no light source that does not produce heat) but when compared to using 12V dichroic reflector lamps the reduction in heat emitted is dramatic making them the perfect solution for lighting systems installed into display cases and counters to keep the ambient temperature to an absolute minimum.

What are retrofit LED lamps?

The “new” generation of retrofit LED lamps have been available for approximately 24 months and have proven to be both reliable and viable replacements for either MR16 G5.3 12V or PAR16 GU10 240V halogen reflector lamps due to their long life and low heat emissions (compared to halogen reflector lamps). The manufacturers state that when operated correctly the average life can be over 30,000 hours. The beauty of using “retrofit” lamps is that they offer a superb light output at a much reduced energy consumption and can be replaced at the end of their life.

As "a rule of thumb" please see the comparisons below between halogen and LED lamps:

3W high power lamp LED lamp = 20W halogen

5W high power lamp LED lamp = 35W halogen

7W high power lamp LED lamp = 50W halogen

What is Track Lighting?

A lighting “Track” is a term used by the lighting industry to best describe a metal (or sometimes plastic) extrusion. The extrusion houses two copper conductive strips that are designed to carry 12V positive + and negative – currents along its length. 12V Tracks are available in varying shapes and sizes and are generally manufactured in 1m or 2m lengths. The beauty of installing a lighting "track" is that the spotlights clip into or around the extrusion and can be repositioned easily in line with changing displays and merchandising.

Why use Track Lighting?

The 12V spotlights that are designed to fit into or clip around the 12V Tracks are generally very easy to move along the length of the track usually requiring only the loosening of a thumb screw or quarter turn of a locking nut. For this reason track lighting offers a great deal of flexibility and is an excellent system for use within applications that are constantly changing.
