This is not exactly ISY question but maybe somebody could help.

I am not sure if I could use LampLinc module to adjust outdoor light low voltage transformer input voltage and thus brightness of 12V outdoor lights. I would like to program with ISY "life ligth scenes" using 4 transformers 200W connected thru LampLincs.

 

Thanks for the help Walter

Most time it is a bad idea to try and dim transformer run low voltage lighting. Unless the lights specifications say they can be dimmed.

An ApplianceLinc V2 would be better and I have found the new hardware version 4.1 can control my cranky loads the older version 1.3 could not. Without sputters and things.

It depends on the power supply. I have some that work well and others that don't work at all.

 

A true transformer instead of an electronic power supply will work perfectly.

 

All you can do is try

I currently have my low voltage lights working with a lamplinc.

The only issue that you may be faced with is: on long ramp rates, the lamplinc module is placed under a lot of stress and my fail. I know this from personal experience.

I only allow my low voltage lamps to come on to 80% and lower them down to 25% for late nights.

The beauty of using the lamplinc, is that I have not had any issues with burning out my low voltage bulbs .... I would burn out bulbs all of the time ... but the soft start using a lamplinc prevents bulb burn out.

If you are using a large load, you may want ot upgrade to the higher wattage Lamplinc.
