Lighting In Retail Signages

Different types of lights are used to make your signage more appealing and leave greater impact on customers.

Lighted storefront signs can enhance the image of your business and ensure that it can be seen by passers-by during the day and night. There are many ways to light up a signage. 

Tubelights

Glow sign box is typically lit up with Tubelights places at a density of one tube light for every 4 sqft of space. The thickness of GSB is to be kept 10 inches to provide enough space for light dispersion overlap between the two adjacent tube lights so that we can observe an even illumination from the exterior side. Sometimes, we use thin tube lights for better warranty life of the lighting.

LED Modules

LED Modules can also be used to light up a GSB apart from their typical use case in Acrylic/Metal signages. In this case, the overall thickness of the GSB is generally not more than 4 inches and the market price is generally to the tune of 850-950 Rs/sqft. In case of LED modules, typically 2-3 modules are used for every sqft of space. The exact per sqft number of LED modules to be used within a GSB varies on the basis of what kind of module we are using.

In LED modules, brightness is not constant. It varies from 3000 k – 10000 k (K – Kelvin). If the LED module is providing lighting beyond 6000K, the color of the light is essentially white and it gets even brighter as we improve the Kelvin capacity of the LED module. Remember come signages are too bright to look at, this is because the LED modules used inside them are of 10000K or maybe a little more. Big brands are really choosy about achieving the adequate level of brightness in their signages as per their brand personality. If the LED modules kelvin level falls below 6000, the light output is no more of white color. Have you noticed some amber color lighting inside the signage… OYO Rooms Acrylic signages mostly. Always remember, the brightness of individual LED module will always be compromised if you go for colored lighting due to its low Kelvin level. However, you can make up for it to an extent by improving the density of modules placed inside the signage.

Typically, all LED modules (Even the digital screens/also known as LED walls in our industry) are composed of two components:
1. Color Controller.
2. LED chipset (Assembly of three chips emitting Red, Green, and Blue light).
When all the three chips inside the chipset are set to light up at a maximum level, we get white light and maximum Kelvin output from that LED module. To attain the color in the light, the light output from individual chips is balanced such that the desired color is formed. This balancing would mean that not all the chips with shining at their maximum level, we lose brightness in the process of attaining color in the LED modules. 
 
The problem with cheap LED modules is that their color controllers get easily damaged which has a direct impact on the light flux capacity (Brightness level) of those modules. Remember observing spottiness in the signages put-up by local shop owners, its because their vendors are using cheap lighting which is giving up too early. Sometimes so early that the sheen of signage is still intact but the lighting has given up. Moreover, poor quality wiring, imbalanced LED chipset, and lack of resistance to dust and water due to the poor molding of assembly components generally result in lack of performance from the unbranded/counterfeit LED modules.

Strip Light

Stip lighting is being used in the signages instead of LED modules. The strip lighting can never be used in cases wherein the signage is required to perform for a long duration. 
 
Typically, the reputed brands of signage lighting do not manufacture strip lighting, and the others who make do not generally provide any warranties on that. It’s because of their circuit is openly exposed and less immune to damage from dust and water. As the strip folds into shape to accommodate the pattern of signage artwork, the light circuit might get damaged. The cutting and joining two strips also requires careful micro-welding which makes the joints vulnerable to damage. However, the greatest advantage of strip lighting is that it requires less space to fit in, and using strip lighting, you can actually reduce about 0.7-1 inch from the letter height. If you are using LED modules, minimum letter height you need is about 2.5 inches. However, in the case of strip lighting, you can get even light dispersion even at the letter depth of 1.5 inches as well. Mostly strip lighting is used for events purposes only.
