The most powerful LEDs for a planted aquarium…

Don’t take my word for it though – you need to listen to an independent review from PFK regarding the Classica OTL-LEDs. And I quote:

To give you an example I compared a 62cm/24.4″ freshwater unit to a 150w metal halide with a freshwater bulb, and I had to dim the OTL down by two thirds to match the PAR output of the halide! I took the halide off a planted tank to swap it for the now dimmed down OTL, and within 15 seconds of putting it on the plants started pearling. So there is definitely something in those freshwater LEDs, in terms of spectrum, that the plants loved.

Now it’s these sort of comparisons that are worth their weight in gold. It’s all about PAR (Photosynthetically Active Radiation) output and it absolutely whooped the metal halides. People, you need to take note of this. Metal Halides have had their day and there’s a new chief in town that is cheaper and more effective and lasts 5 times as long.

It’s true that LEDs have had a rocks road to begin with but now things are different. I would recommend these LEDs for those of you who want complete control over their lighting, run a pressurised CO2 system and are serious about their planted aquarium. Is this you?
