LET Lighting Dimmable T5 RetroFit, how to add dimmable control to Apex?

[Andrew Schubert]

So I setup a hybrid set of T5 dimmable T5 with the LET Lighting retorfit kit sold by BRS https://www.bulkreefsupply.com/dimmable-t5-ho-miro-4-retrofit-kit-let-lighting.html.

I just purchased the 2 channel dimming cable from BRS to hook it up to my Apex Control but not sure how to do that? The retro fit lights have to wiring ports saying wire colors (violet and gray). However, the Apex dimming cable has 4 wires (yellow, green, red, black).

So which cables go where to actually get this to work?

I had this same issue.... Stand by. Taking pictures.

Looks like you have the same cable I have, but just to be sure, with the clip facing away, the RJ45 has the wires crimped in this order: Black, Red, Green, Yellow, Black Red, Green, Yellow.

For me, I used the black and red only (black to violet and red to gray), then plugged into the V3/V4 port. I programmed, and good to go!

Just remember you have to run those dimmable t-5's for 100 hours before dimming them.

Hope this helps.

Yes you only need the red and black wires.

Hello there I just recently added t5 to the tank and I followed the wiring you have to connect to the vdm however it does not turn off completely what am I doing wrong

 

[BornHandy]

Does it go from bright to dim at least?

Yes it is very very dim but doesn’t completely shut off

Not sure if you want to go down this road or not, but I would just have the controller kill the outlet at the right time. That would solve the problem. If you wanted to troubleshoot, you could try the other port to see if the port you are using is the problem..
