Controllable T5’s

[Jase4224]

Hi guys I need some help. I have two 80W T5’s that I would like to be able to control (sunrise/sunset) without the sudden on/off that I can’t stand.

I assume that I need to get dimmable ballasts but how do I control them?

I have seen controllers for diy LEDs such as the bluefish and the storm X but I want something like this for T5 control.

Any suggestions appreciated!

You may not be able to do this with 5ft 80 watt bulbs all the dimmable ballasts I've seen max out at 48" and 54 watts.

When I ran T5s I couldn't find any dimmable ballasts, I just had sets of bulbs on different timers that would turn on and off gradually.

These ballasts are controllable with an Apex VDM module but like I said they only run 54watt bulbs. BRS sells them in 24/39 watt also. They use 0-10volts dc to control them. The controllers you mentioned use PWM to control leds. I am looking into using reef-pi to use as a controller for a t5 led hybrid set up.
I am able to control my LEDs now I just have to figure out how to control the fluorescent ballasts with 0-10 volt dc.

Thanks for the info. I’m also looking at making a T5/LED combo using my old Giessman Infinity so removing the halides. Do you have a thread I can follow?

I'll be testing and working it into my reef-pi build thread.

@Diamond1 - Here is the same ballast for about 1/3rd the cost. You can also find various other T5 dimmable ballasts on the same site.

Those look great. Unfortunately I need the HEP 24/39 watt like the ones BRS sells for 65 bucks a pop.
