The installation and operation of your fixtures has been designed with simplicity in mind. However, as every site has its own pre-existing conditions the amount of technical expertise and labor will vary.

Photometric Analysis

Most projects begin with a customized photometric analysis of the tower and grounds site layout. The analysis will determine the best location to mount the fixtures. Typically this is on poles, but can also be on an existing structure, ground-mounted, or even tank mounted.

Please pay careful attention to install the fixtures per the analysis as this will ensure the most uniform coverage on the tank. In addition to the precise mounting location, the analysis will also stipulate mounting height and lens angles.

Receiving Your Products

Please ensure that you have received all of the contents of your order prior to installation. Typical orders consist of the following components, although your order may vary, and are shipped separately as follows: Poles, Tenons/Mounting Brackets, Base Plates, Fixtures, Controllers. Specification sheets for each of these items can be found at


Please refer to the following sections for installation of each of the aforementioned components.


New service, if needed, should be installed by a licensed electrician. The MSL-FLC-LW023-A Tower Series LED fixtures run on 110VAC. The fixture power cable has three wires: phase (brown), neutral (blue), and ground (green). At full power each fixture will draw 11 amps at 110V.

White light fixtures will have a demand based upon wattage. Please contact Main Street LED for the appropriate service size for white light only fixtures.

Conduit should be run to each pole site and run through the pole and base plate to each fixture location. For installations with a hard-wire control system, the shielded direct-bury Cat 5 cable can be installed in the same trench (not conduit) as the electrical wire. This should also be run through each pole to the fixtures.

The Cat 5 can be run to a J-box with a screw terminal and split to each fixture. If the control transmitter (see below) is located within a structure, a 1” conduit is sufficient to allow both the electrical and Cat 5e cable to pass to the outside.

Install a photocell (supplied by electrician) in an area free of obstructions. The photocell should be installed after the Transceiver (see below) and before the fixtures. In other words, the Transceiver should always be powered on.


A typical configuration consists of 39’ round tapered steel poles. However, mounting locations that are closer to the tower, or sites with special constraints, may require taller poles. Most poles provided by Main Street LED are hurricane rated and will easily support the weight of multiple fixtures. Sites with existing poles, or poles provided by the end user, should be rated to accommodate the weight of the fixtures with the appropriate wind loading. Each MSL-FLC-LW023-A Tower Series LED fixture weighs 66 pounds.

Poles should be installed per soil conditions. Main Street LED is not responsible for incorrectly set poles. While direct-bury poles are an available option, most poles should be installed on a concrete pedestal. Monotubes are available upon request. The bolt pattern for the poles is shipped in advance of the pole arrival. Please allow sufficient cure time for the concrete before installing poles.

Mounting Brackets, Base Plates, and Fixtures

Steel and aluminum poles are shipped with a 2-⅜” tenon top. Install the tenon top onto the top of the pole using the included bolts. Where multiple fixtures are installed per pole, a bullhorn, wrap around, or other bracket system will be provided. (Note: wrap around brackets are specifically for wood poles.) Each MSL-FLC-LW023-A Tower Series LED fixture must be installed on the supplied base plate.

Prior to installing the fixtures on the base plates/poles, you must first program each fixture! (Note: white light fixtures do not require any programming). Please see “Programming the MSL-FLC-LW023-A” below.

Once the fixtures are programmed you are ready to bolt them onto the base plates. Align each fixture with the ½” inch holes in the base plate and bolt them down using the supplied bolts.

Slip the base plates directly on top of the tenon or bracket. Secure each base plate to the tenon or bracket using the 3/8-16 tightening nut. Pull the electrical and control wires through the 1-1/2” diameter center hole of the base plate.

As stated above, Main Street LED fixtures are manufactured with three electrical wires: the brown wire is phase, blue is neutral, and green is ground. If the Power IN cable has a quick-connect plug on it, clip it off and wire the conduit directly to the cable.

Power on the fixtures and aim the lenses for maximum light exposure onto the tank. Tighten all lens screws to secure the lenses into place.


Depending on the site configuration and installation you will have a wireless or wired controller which will consist of the following:

Wireless: One (1) NEMA enclosure for the transmitter and multiple smaller enclosures (one for each receiving location).

Wired: One (1) NEMA enclosure for the transmitter and Cat5 cabling with quick-connect terminators for each receiving location.

For wired connections the transmitter should be placed close to the breaker panel and each Cat5 cable will most likely run with the electrical wire.

For wireless connections the transmitter should be placed somewhere on site that has good line of site to each receiving control box. All control boxes will need 110V unless otherwise specified.

The control system will come preassembled and should only need to be plugged in. However, if instructed by Main Street LED to access the controller it is helpful to know the following components and their uses:

LTech WIFI-106 - Receives signal from mobile devices and private wifi networks (2.4GHz Wi-Fi, 802.11b/g/n)

LTech Ebox - Converts wireless signal to DMX signal

LTech 870S - Sends/receives DMX signals

The L-Tech WIFI-106 broadcasts a 2.4 GHz radio signal to the L-Tech EBOX-DMX which then converts the signal to the DMX512 protocol. This signal is then sent to the L-Tech 870S DMX 512 Transceiver which then broadcasts the DMX 512 signal to a receiving L-Tech 870S DMX 512 Transceiver.  The Transceiver is then plugged into the MSL-FLC-LW023-A directly via a pigtail or indirectly via a CAT5 cable. This DMX 512 signal is used to control the lights. Each controller is waterproof and comes with its own power supply.

You must ensure that the antennas are all pointing directly upward within the enclosures. Do not change any of the pin settings on the LTech 870S.

The following image shows a transmitting controller (large NEMA enclosure) and a receiving controller (small NEMA enclosure). Depending on your installation you may have multiple receiving controllers.

If Fixtures are Controlled via a Wireless Connection

Plug the pigtail from the NEMA enclosure (see below) directly into the power output cable on the back of the base of the MSL-FLC-LW023-A. The enclosure can be secured directly to the fixture or pole.

Each connection is a specific size so it is impossible to screw the cable into the wrong connection. Tighten the watertight screws for both cables. Fasten the receiving NEMA enclosure to the side of the fixture, preferably within line of sight of the transmitting controller. A video explanation of the cables and connections can be found  here:

If Fixtures are Controlled via Cat5 Wired Connection

Plug ends will need to be wired together at each Cat5 connection where a DMX IN connection is desired. Main Street LED will ship these plugs separately with the main controller.

The fixtures are manufactured with 2.5’ DMX OUT and DMX IN cables which allow them to be connected directly when sitting side-by-side (as when they are on a bullhorn).

Multiple fixtures may be daisy-chained together using CAT5 cable. If this is your preferred installation method then we recommend clipping the DMX OUT cable from one fixture and the DMX IN cable from the next fixture and hard-wiring the fixtures together.

Remote Control / Mobile App

There are two ways to control the colors of the fixtures: 1) using the supplied radio frequency (RF) remote control; and 2) using the mobile app. The RF remote is very basic and will cycle the lights between the pre-programmed settings. The mobile app is much more versatile and allows for customization of colors and programming of zones. To install the mobile app follow these instructions.

From a mobile device, download the ‘WiFi - 106’ app on the Google Play Store or iTunes Store.

The app connects directly to the WiFi-106 and doesn’t require a formal WiFi network. Once the app has been installed on your mobile phone, navigate to your phone’s wifi settings. You will find a new wireless network titled WiFi-106-SSO-0 (default is no password or MainStreet7). Once connected to the network open the app to find the following interface:

The L-Tech WIFI-106 controller may be sent to you pre-programmed by a Main Street LED technician based upon your installation. Please refer to the manual if you would like to create your own programs. Main Street LED technicians are available to create additional programs for a fee.

With the controllers in place and receiving power you are now able to control the fixtures via the mobile app. Enjoy!

Programming the MSL-FLC-LW023-A

Prior to installation all fixtures must have both the mode and channel programmed and saved into the base. Once programmed, it is strongly recommended that the fixtures be powered off and back on again to ensure they have maintained their programming. Programming is a simple step on the ground but very laborious and time-consuming in the air! Please read the following instructions carefully to program each fixture.

There are four buttons and an LCD screen on the base: Menu, Up, Down, Enter. Scrolling through the Menu will provide different options.

Assigning Mode and Channels to the MSL-FLC-LW023-A

Each fixture must be put in 4 channel mode (Note: the default mode for each fixture is the 12 channel mode. This MUST be changed to 4 channel). On the base of the MSL-FLC-LW023-A, press the Menu button until you get to the “??ch” setting and use the up/down buttons to set it to “04ch” and press the Enter button to save the setting. Repeat for all fixtures. Failing to press enter will cause the fixture to default to “12ch” the next time it is powered on.

Once the mode is set, you can now assign each fixture its own channel. The MSL-FLC-LW023-A must be assigned a channel in order to be individually controlled by the controller (Note: each fixture can only display one color at a time.) Multiple fixtures set to  the same channel will project the same colors.

Press the Menu button until you see the channel setting mode (beginning with “A000”). Press the up arrow key until the display reads “A001” then push the Enter button to save the setting. Now unplug the fixture and plug it in again. Scroll through the Menu options to ensure the mode and channel have saved.

For the second fixture repeat the previous step until the display reads “A005”. Follow this chart for the number of fixtures in your installation:

A tutorial video is also available for setting the channels can be found here:

A tutorial video for setting zones can be found here:

Fixtures can be combined into pairs or groups to simplify control by setting all fixtures in the group/pair to the same channel.

To manually program the colors via the base please follow these steps:

  1. Ensure the MSL-FLC-LW023-A is powered on.
  2. On the display on the base, press the menu button until you see “r255”. This is the power output of the red color.
  3. Press the arrow up or down button to change the power output to the red chip, thus changing its color. “r000” sets the red color to 0 which eliminates any red in your output.
  4. Press Enter
  5. Follow the same steps for the four colors R, G, B, W (red, green, blue, white) represented by the digits: r, 9, b, o (R=r, G=9, B=b, W=o).

For a solid white color the fixture will be programmed as follows: r000, 9000, b000, 0255. Leaving all colors at 255 will also produce solid white but will use much more power and may reduce the life of the fixture. The MSL-FLC-LW023-A does have an internal temperature control that will automatically reduce the output of the colors if the fixture is too hot. The temperature can be checked by pressing the Enter key on the base.
