The lack of a dimmer is a bit confounding. The lower priced models have a built-in dimmer, so I'm a bit puzzled as to why this one doesn't. That aside, it's an incredible light!
You think jumping up from the E series on a 30cm to the S would have much impact on growth and coloration (making red plants more red) E is 1000 lumen 16 watts S is 1200 lumen 23 watts.
Thanks for the response Logan. I have the Twinstar dimmer so would you start at level 5 on the S for 8hrs since that’s what my plants are use to an 8hr schedule. I’m currently on level 7 with the E series light.
Unfortunately no app integration out of the box with this light. I have a strong feeling the next version of TWINSTAR lights will be moving in that direction though
