Thanks Detlef, that was the one I used to make the claim that the ADC 850 probably is a regular tri-phosphor (and thus ought to have high PUR-efficiency like the Aquarelle/Aquastar/Triton).
That is also a tri-phosphor and probably have a high PUR-efficiency - I need the wattages and lumens-output to calculate the exact PUR-efficiency though.2. Daniel, Arcadia has a "Marine White Lamp" out, rated 9500K, highest energy output around 400-480nm, good colour rendition, supposed to be used for marine environments. I would appreciate if you could run PUR efficiency testing on this one also!
In my beta calculator you can upload whatever action spectrum you want. I have one for Zooxantheallae and it have a rather similar AS to green plants.3.The action spectrum (AS) was derived from the green Anacharis/Elodea. Red plants would have a much different AS I guess requiring more energy in the blue, green and may be yellow part of the spectrum vs. a green plant to compensate for the red light which they can't efficiently use (because they reflect reds).
In trying to find the best suitable lighting for growing R E D plants should'nt we know the PUR ratings calculated from a red plant's AS curve as well?
If you find one for red plants let me know and I would be glad to upload it into the calculator.
As I answered in your other thread, that is extremely low light. It's the equivalent of a 75% reflected 7 watts bulb over 150 gallons.Hi i need some help I have a new lux light meter with waterproof probe. I put the probe on the botton of my aquarium and the reading was 450-500 light intensity is this high, med or low ???
I would like to know what plants i can put my aquarium also have o2 Will someone help we
My guess is that the probe must have been shaded when you did the measure?
