Hello everyone, I have been using the Chihiro style (mine are actually clones??!) lights on my 60cm tank without any issues. They don't render or grow red plants that well but it's probably low CO2 etc on my part. 20181103000802_IMG_6322 by Reb El, on Flickr Since I really love the slim look of these lights and don't have the DIY knowledge to replecate them, I thought I'd try my hand at installing RGB LED 5050 in the middle row. The outer two rows will be the original 5630 (5730?) LEDs which are meant to be 7000-8000K. For maximum effect I thought I would go for double row RGB LED. I don't think I will try to colour tune as much. Just run them at full power although I may change my mind if they cause too many undesirable colour casting at full power. if colour needs to be controlled, then I could use this sort of thing although I would like to keep the wires very clean and neat. My first hurdle is the tiny little allen key required to dismantle the light! 20181103000831_IMG_6323 by Reb El, on Flickr I am also awaiting the RGB LED to be delivered. https://www.ebay.com.au/itm/Double-...f170548e2:m:mhKRSIK1hGR7INiMEzQ79Yw:rk:7:pf:0 I will keep you updated and would welcome any input.
