1. Is it discreet shipping/package?

-Yes. It is discreet shipping. All our packages are shipped with plastic foam to stick the light and keep it safe; and without any labels “grow lights”, “grow tents” or brand names are mentioned on the packages.

2. I got the old version of light, and now I want a dimmer box and daisy chain, how can I do it?

The old and new versions are very different in internal structure, so it can’t just add a dimmer knob to realize the functions. Now only our TSW2000 & TSL2000 can have this function by replacing it with a new driver. The whole driver set would cost 100-150 USD. So we would not recommend customers buy it.
