Will it Dim?

I recently purchased a new home and the good news is every switch box has to have a neutral as it was built to the new electrical code. The other nice thing is all the recessed lighting is LED; the problem is that all the recessed lights are REALLY bright and of course no dimmers. The brightness is helpful for the porch with a single recessed light but my kitchen has 6 recessed lights, and it’s right next to a dinning area with 3 additional recessed lights.

So the big question was: Will is Dim?

The first step was to pull the cover off one of the LEDs to see if I could figure out who the manufacture is. This is what I found:

So off to Google I went; first I did a search for “Lynk Labs”. What I found wasn’t the manufacture of the fixture but the manufacture of the light module it self. I looked around the Lynk Labs website for a few minutes and found this: http://www.lynklabs.com/index.php?main_page=product_info&cPath=67_69&products_id=280

I then started looking at the spec sheet: http://www.lynklabs.com/images/datasheets201509/120/SR46-14W-120%20%20V6.pdf

I was able to find my module: SR46EP2H14W52WDIH-120
The lights use 14 watts and produce 1040 Lumen each! So that explains why my kitchen is so bright. 9 x 1040 = 9360! This is nice when you are cooking but not when you are eating dinner at the island and trying to watch the TV on the other end of the room. They are also AC-LEDs, and I found that really interesting.

To my surprise on the first page of the spec sheet it says: “Dimable Module” and further down it says my modules will “Warm on Dim”. Sounds like the color temperature will change as you dim them, I’m good with that.

The next step was to figure out if the GE 12729 Z-Wave Smart Dimmers could dim these LEDs without causing problems. I started doing some research and found that the load should really be 40w or higher; basically the dimmers work better when there is enough load. The 9 recessed LEDs are split between two sets of 3-way switches. The kitchen is 6 lights x 14 watts = 84 watts and the dinning area is 3 lights x 14 watts = 42 watts. So I was a little worried that 3 lights would not be enough load but I carried on anyway.

I purchased 2x GE 12729 & 2x GE 12728 add-on switches as this is a 3-way setup. I also found out during install that the two sets of lights are on different breakers but this wasn’t really a problem. The one box that has a switch from each set of lights has a neutral from each leg and I was able to keep them separate. So no neutral loops and no stealing a neutral from another leg.

Also seen in the video is my lamps and ceiling fan that are also being controlled by GE Z-Wave dimmers.

The only problem I have now is wondering if the two recessed LEDs on my back porch will dim as 2 lights x 14 watts = 28 watts. I also have other parts of the house that just have a single recessed LED on one switch. I will most likely just install a GE 12727 on/off switch like I did for my front porch light.

My goals is to slowly replace every switch in the house with GE Z-Wave switches.


Just a note from my empirical data, Linear dimmers work better and down further than GE. They also don’t seem to have the same minimum load restrictions. I have all Linears after trying 2 GE models.

Definitely subscribing to this thread, was about to embark on replacing all my GE Links with GE 12724’s (paddle dimmer) and I am worried about the minimum load, even on the switches with the most bulbs (four BR30s) I still might not make 40W… There are some higher wattage BR30s or could even use PAR30s but then that’s getting into INSANE levels of light…

I will post back here if I ever get around to testing the GE Dimmers with a lower wattage load. I would love to dim the LEDs on my back porch.

You should have no problem with the GE 12724 dimmer since it requires a neutral. Dimmers with a neutral shouldn’t require a minimum load since the load isn’t required to power the actual dimmer like a 2 wire dimmer does. I am running the 12724 with a 20 watt load and it works perfectly.

That’s good to know.

Thank you for the confirmation! I will get buying some GE Z-Wave switches to replace these smart bulbs, plus I hate ZigBee AKA, even more 2.4GHz interference…

This is why I have a dual band access point :smile: 5Ghz is the way to go.

Now with the addition of my z-wave network I got stuff on 900Mhz, 2.4Ghz and 5Ghz…

True though I still don’t like polluting the band…
