I'm in the process of starting a planted 40B and have yet to purchase lights. I've previously had T5HO, but never LED. I like the idea of LEDs in that they stay cool and usually have night light options, but am not sure how they do with plants. I found a 1200 lumen fixture that I liked. I'm going for low light, no CO2. Would that be OK to grow these types of plants, or should I stick with normal bulbs???
