About Whole-lit Channel Letters

Sample case

Whole-lit Channel Letters
  • Whole-lit channel letters require a power source so that the LED light source can provide good light. Although solar energy and wind energy are used by more and more users due to their green characteristics, when used as power sources for illuminated signs, these green energy sources need to be matched with energy storage batteries to ensure the stability of the current. Therefore, the stability and cost of this kind of power supply will all be worse than the mains power. Therefore, we recommend using mains power. Whether it is civilian AC or industrial AC, it will be more stable.
  • The vast majority of LEDs are driven by safe 12V DC power. Therefore, if the mains power is used as the power supply, the AC transformer is required to convert the AC power into the 12V DC power required for LED operation. Therefore, it is recommended that before purchasing, you first understand the voltage of the AC power at the place where the whole-lit channel letters will be installed, so that we can provide you with a suitable AC transformer.
  • In order to reduce line loss, we recommend that the length of the wire from the signage to the AC transformer be controlled to 3 meters (about 118 inches), otherwise the LED may not fully emit light due to excessive current loss.
  • The AC transformer will generate heat when working, it is recommended that the AC transformer be placed in a place with good heat dissipation. If the AC transformer cannot dissipate heat smoothly, the service life of the transformer will be seriously affected.
  • The installation of whole-lit channel letters usually requires drilling holes in the wall, so it is recommended that you confirm with the landlord what restrictions there are on drilling holes before purchasing.
  • Some cities, communities and landlords have certain restrictions on the brightness and color temperature of illuminated signs, so it is recommended that you understand these restrictions before purchasing.
  • The border of face-lit metal channel letters can be made of metal with regularly arranged dense holes, so that while the front of the sign shines, the light can also shine on the wall through these holes on the side. If you need this kind of channel letters with illuminated front surface and sides, please contact us.


  • Can be letters, numbers and logo.
  • Each individual part is separate.
  • The front surface and the border of the letters are illuminated.
  • Using CNC engraved or fabricated acrylic 3D letters shell.
  • LEDs are installed in the letters shell as light source.
  • Can be used indoors or outdoors.

Flush mounting mostly.
  • Too small letters have limited space in the signs shell, causing too hard to place the LED lights evenly, unless using PCB LED, which fit for the mass production only.
  • The CNC engraved acrylic letters shell is used by default, while the fabricated acrylic letters shell is more suitable for larger letters.
  • Fabricated acrylic letters shell is troublesome to transport, even if it is carefully packaged, because acrylic is a fragile material, so it may cause damage during transportation.


One set of basic backlit metal channel letters consist of the following components:

  • Acrylic letters shell
  • LEDs
  • Aluminum back-panel
  • Cables
  • AC transformer

Acrylic letters shell

CNC engraving or fabrication
Default thickness
  • Using CNC engraved acrylic letters shell mostly.
  • The thickness of the fabricated acrylic letters shell would be about 1.97"(50mm) at least.
  • Usually, only opal acrylic is used to make CNC engraved acrylic letters shell, because there are few thick colored acrylic sheet that can be used in this process. So have to purchase customized colored acrylic sheets, and the MOQ of this customized raw material will seriously affect the implement ability of this solution.
  • If the acrylic letters shell is required to have a specific color, fabricated color acrylic letters shell are usually used.

110v~240v AC
12v DC
  • The waterproof AC transformers are using MeanWell brand LPV-60V-12 default, IP67, -30~70℃ wide operation range.
  • The Non-waterproof AC transformers are using LRS Series by default, 300VAC input surge, 5G vibration, 70℃ operations.


Most of the installation methods of whole-lit channel letters are flush mount or raceway mount, using stud bolts to install the signs on the wall.

  • Flush Mount: This installation method uses stud bolts and is installed separately on the building facade using the mounting holes. The wires used to power the lighting are fished out of the wire holes and mounted behind the wall so light source maintenance can be easily done from behind. Typically, each individual illuminated sign part has 2-3 stud bolts and 1 wire, so 3-4 holes need to be drilled in the wall for this. Obviously, this installation method will increase the installation workload, but since the wires and stud bolts are buried in the wall, the installed signs will be sleek and sophisticated.
  • Raceway Mount: In this installation method, the sign is first mounted on a slender metal mounting structure called a "raceway", usually made of aluminum or stainless steel, and then the raceway and signs are mounted on the wall as a whole. The interior of these mounting structures can be used to house electrical wiring and AC transformers. The advantage of this type of installation method is that it has fewer holes need to be drilled, which can be an important consideration for building owners or landlords, and it also makes it easier to install and renew the signage, while creating an off-wall visual for the sign, so the three-dimensionality will be better. However, due to the existence of the "raceway", the integrity of the sign and installation wall will be weakened.

To ensure your signage is installed correctly for optimal display and longevity, we recommend hiring professional installers. We will provide a 1:1 layout template to show the hole positions of stud bolts and wires, the installer will drill holes on the wall according to these hole positions. If it is an illuminated sign, the wiring work of the wires needs to be completed. We will provide installation instructions, wiring diagram and necessary installation accessories to help your installers complete the installation correctly and quickly. If you are unable to find the professional installers, please let us know and we will put you in touch with one of our partners to find good installers for you.

  • The recommended working temperature means that based on our experience, the sign can keep working within this temperature range for a long time without significantly reducing the service life. Generally speaking, illuminated LED signs can work in a wider temperature range, usually -30℃ ~ +70℃ (-22℉ ~ +158℉) but the harsher environment will shorten the service life of the signs.
  • Stud bolts are necessary for installation, used to fix the signs on the backing wall.
  • Nuts and washers are only fit for situations where people can work at the other side of the backing wall, then can use washers and nuts to secure the stud bolts to the wall.
  • If you need the whole-lit channel letters off the backing wall, we will provide the stainless steel tube spacers with 20mm (0.8") length by default, electrical wiring and stud bolts can through the tube spacers, used to make all the individual part of the whole-lit channel letters have the same distance between the backing wall.


  • In three years, if it is not the man-included damage, we will send you the damage part.
  • After 2 years, because of the half-life, the LED lighting would be weaker. In order to keep the effect of the signs, we suggest changing the LED lights when you feel the brightness could not reach your requirement.
