Essential Info

This dimmer is designed to be installed within a junction box or in a ceiling fixture allowing you remote control over lights that may not have a direct connection to a wall switch. This allows you to pair the dimmer with any number of INSTEON remote controllers.

This dimmer controls incandescent bulbs. If you need to control a fluorescent light fixture or an appliance, try the In-LineLinc Relay.

INSTEON also offers a Micro Dimmer Module that wires in behind your existing switches or fixtures. This allows you to keep your existing antique, toggle or decorative wall switches while adding the customizable, dimmable INSTEON remote control functionality.

Note: As with all dimmers, the In-LineLinc may feel warm during operation. Rigorously tested and approved to UL-standards, the amount of heat generated falls well within approved limits and poses no threat to your home or the lifespan of the device.


What's Included

  • In-LineLinc Dimmer - INSTEON Remote Control In-Line Dimmer (Dual-Band)
  • Quick-Start Guide
  • 4 wire nuts
  • More Info

    This dimmer can be used with dimmable LED bulbs to help you save even more energy. While performance may vary between manufacturers, we have found that Sylvania Ultra LED dimmable bulbs offer great performance with a wide and smooth dimming range. The Ultra LED series include the following types: Standard (A-Line), MR16, PAR16, PAR16 GUI10, PAR20, PAR30LN and PAR38.

    Easy To Install
    The INSTEON In-LineLinc Dimmer is easy to install and set up. Its small size allows installation in a standard J-box or in a ceiling light fixture. Control each kitchen light individually or rows of can lights with a single INSTEON In-LineLinc Dimmer. Learn more about INSTEON here.

    Perfect for Locations without a Switch
    Whether you're planning to install recessed lighting or have already done so, you don't need to go through the hassle of running the wiring for a new wall switch. By installing an In-LineLinc in a fixture box, you'll be able to control the lights from any location in your home. Simply install the In-LineLinc in the fixture box, link it manually or via HouseLinc - INSTEON Desktop Software, and you'll be able to turn lights on and off and dim them using any INSTEON-compatible controller. For maximum personalized control, wire an In-LineLinc to each non-switched light for the ultimate in mood settings.

    Adjustable Ramp Rate
    Adjust the speed at which the controlled light turns on or off, also known as the ramp rate. For example, you may want the light in the stairwell to turn on instantly so you can see where you're walking. Alternatively, you may want the light in the master bathroom to ramp up in a soft, gentle fashion so you're not blinded in the middle of the night. The ramp rate is adjustable between 0.1 second and 9 seconds if programmed locally. The ramp rate can extend up to 8 minutes (for a simulated sunrise or sunset) if programmed using software such as HouseLinc. This is a great addition to your morning alarm, slowly turning the light on to help you wake up.

    Easy to Program
    Programming an In-LineLinc can be easily done a couple of different ways. The Tap method is best for your initial setup. Simply go into linking mode on any INSTEON-compatible controller and then press the set button on the In-LineLinc for 3 seconds; the load and the status LED will flash. You are now linked and can control the In-LineLinc from the controller of your choice. Keep in mind that once installed in a fixture, the In-LineLinc will not be easily accessible, thus making new links and scene programming difficult. We recommend using software such as HouseLinc 2 - INSTEON Desktop Software to manage the links of your In-LineLinc after it is installed. Remember, you will need to have the INSTEON ID in order to program with software.

    Scene Lighting
    Scenes allow you to control multiple lights, rooms or even the whole home with a single command. Because the In-LineLinc Dimmer can be a member of more than 400 scenes (i.e. "Movie Time," "Party," "Romance," etc.), you'll be able to launch various lighting scenarios with a single button press. These are elegant features usually found only in systems costing tens of thousands of dollars and requiring extensive rewiring of your home. All member lights can ramp to your independently desired brightness levels at your chosen ramp rate(s). So one set of lights can dim slowly, while another set turns off instantly, all controlled with one command from one button. If you want to control multiple scenes from one controller, we suggest the INSTEON KeypadLinc.

    In-LineLinc Dimmer is fully INSTEON compatible and X10 ready. Homeowners with existing X10 networks can easily migrate to an INSTEON network without having to discard all of their existing X10 devices. X10 ready means that it can respond to X10 commands from an X10 controller. Please note that INSTEON devices repeat INSTEON signals but not X10.

    In-LineLinc is dual band so it has the ability to communicate using both the electrical wires in the home (powerline) as well as using radio frequency (RF). This increases reliability not only for In-LineLinc but for all devices on an INSTEON home control network (similar to the function of an Access Point).

    Non-Volatile Memory
    All In-LineLinc Dimmer settings are stored in non-volatile memory and are not lost during power failures. Additionally, in the event of a power loss, the In-LineLinc Dimmer will return to its last brightness level when power is restored.

    Certifications and Warranty
    All In-LineLinc Dimmer products are safety approved. The factory for INSTEON products is ISO9001 certified. In order to meet the ISO9001 standards, the entire factory underwent rigorous inspections of procedures and policies before being certified. The certification received was based on its dedication to high-quality management systems and strict adherence of quality control systems and guidelines. Because of this, INSTEON stands behind the entire In-LineLinc line of products with a full 2-year warranty.

    Dimming function not compatible with some LED bulbs. Otherwise an excellent product.
    JOHN -- avon, OH   2/18/2014
    Not reliable long-term.
    RICHARD -- katy, TX   1/16/2014
    GARRICK -- rcho sta marg, CA   1/3/2014
    Took several hours before I could finally pair this device with the dimmer. A couple more hours to figure out how to turn on the lights to 100% brightness.
    John -- Ohio   12/29/2013
    As with almost every Insteon device I've owned, the long-term reliability of the 2475D is poor. This unit worked for two years then completely died. Completely unresponsive, NO factory reset, no lights, nothing. I've got a couple dozen Insteon device in my house and I'm getting very tired of replacing them every 2 to 3 years due to their poor design. I'm glad the electronics in my other devices don't just up and die like Insteon devices do. Can you imagine driving your car and all of the sudden the electronic just die and then having the auto manufacture say sorry two years are up, you're out of the warranty period? Completely unacceptable long-term performance! SmartHome get your act together!
    GREG -- sunray, TX   12/22/2013
    Have had installed for about 3 weeks using a 4-Scene mini remote. Must use incandescent bulbs for dimming feature. Not sure about LED's yet. Housing is a tight fit in a ceiling junction box. We're using units in each of two pendant lights flanking our bed using two 4-Scene mini remotes. Each remote can be programmed to operate each light independently. Great tech support on chat line also. Tight fit in the junction box is the only reason for not giving five stars.
    DAVID -- alameda, CA   12/2/2013
    Wiring and setup was easy, works great out of the box. Far superior to previous X-10 setup. Time will tell.
    Cliff Schuyler -- houston, TX   11/12/2013
    Great product. This product is especially useful if you want separate control over different lights from one power circuit. In my case, I did a kitchen remodel and wanted to have separate control over 6 new recessed kitchen lights on one circuit and the center island pendant, as well as over cabinet lighting. To hardwire separate wiring to each of these lights would be impractical and expensive, unless with new construction. In my case, all lights are on one circuit, then each branches off to an individual in-line dimmer to control it's respective lighting in my case, one for the pendant light, one for the 6 recessed lights, and one for under/over cabinet lights. Now each can be controlled separately and with scenes through a six or eight way control switch. Setting up these devices like I did was made much easier with the Insteon hub I am not too fond of the hub overall, but it does make the setup of the switches much easier and for that alone it is worth it. Keep in mind that if you do as I have done, the total load of all devices must not exceed the circuit maximum. Generally for lighting it won't be a big deal - especially if you use low wattage bulbs LED's and CFL's.
    GREG -- north las vegas, NV   10/16/2013
    Love them, Links to 8-button keypad flawlessly.
    TIM -- long beach, CA   10/3/2013
    Love addition of the red/green led and local control buttons, however it is lacking full x/10 control. It will only handle a primary address, not scenes inx/10. This deletion completely baffles me since it is just a software issue that is readily available. Here's the biggie; the brackets for mounting in gang box have now been deleted. This unit is so dangerous. I was so told by support that it will just sit there in the normal gang placement. It can touch up against adjacent gang mounted items such as outlets or the side of the gang box if metal and short out or start a fire. There needs to be an immediate fix for this issue or recalled. INCLUDE removable brackets please.
    ROSS -- long beach, CA   10/3/2013
    It would have been 5 stars if the instructions had had some hints or a reference link with examples of sending the address without the [on command]. Very pleased with the operation once I solved the problem. I have 8 X10 modules and needed to add more controls on the X10 system. The manual was not clear to me and I was unsuccessful with 2 support calls. My issue was solved by experimenting with the controller - I was able to send the address without an [ON] command by holding down both the [ON] and [OFF] buttons at the same time and then pushing the [ON] button. It linked without repeating the process the 3 times shown in the instructions. Very pleased once the ambiguity was overcome.
    HOWARD -- arvada, CO   7/20/2013
    Worked perfectly, setup was effortless. Would buy again.
    PAUL -- coweta, OK   7/12/2013
    Used as an in-line dimmer for one light on a circuit. The dimming function works perfect. The module is slow (5+ seconds) to respond when energized. If used as a switch and always energized, I'm sure it would work perfect.
    ROSAMOND -- san pedro, CA   4/24/2013
    My overhead living room light was 'hot' but had no corresponding wall switch. Rather than go through a costly and disruptive traditional wall-switch installation, this in-line dimmer synched to the mini-remote switch was the perfect answer. It was so easy to install and it works beautifully. Problem is solved.
    BENNY -- las vegas, NV   4/12/2013
    works perfect!!!!
    PAUL -- sykesville, MD   3/16/2013
    Works well - especially with Indigo 6 and the IOS app. I can control a set of lights easily. They can be dimmed or turned off and on.
    JANET -- lorton, VA   3/7/2013
    It works great, easy to install and program. I will definitely use them again. I retired as a electrician 6 years ago and could have used these in many situations. I could have used the non dimming module to turn a multitude of things on and off remotely. Larry Catlett
    KEITH -- sparta, NJ   2/28/2013
    Very simple installation. Pared with ToggleLinc switch easily. Works great.
    HENRY -- fairview, TX   2/11/2013
    Works great!
    WILLIAM -- salem, VA   1/10/2013
    I'm sure that it will work but it is very bulky. I need something smaller. Likely to return for that reason.
