My first 120L aquascape with dry start HC

[TTerry]

I have not seen the S series yet, but i read from other forum the connector is different from E series. And SP series is hanging version, so it will probably help with PAR/ spread. I was eyeing on S series too haha! Anyway, i took out the dimmer. Cos the brightness of the light just to nice to be lowered

Passive dimmers does not work on S series, that's for sure as highlighted by the Twinstar UK supplier on UKaquatics. Good to know that the Chihiros dimmer do work on the Twinstar, but since there is no real test, it may not be the best to use it for now.

What I mean by real test is that the dimmer, LED and power adapter runs cool with no flickering for at least 1 year of usage with no burn out. If somehow or rather really spoil, you may end up voiding the Twinstar 1 year warranty with EOA.
