Never said YOU mentioned a premium for the KZ Fiji Purple... I mentioned it! hehe =D I have found that they are near $30 a bulb everywhere you look, unless you can get lucky and find a sale. That is approximately 2-3X as much as other "red" producing bulbs like Zoo Med Flora Sun and Wave Point Red Wave (now called Color Wave) which can be had around $10 a bulb, and the Current/True Lumen Freshwater Flora and Aquatic Life Roseate which can be had around $15 a bulb... Hey, maybe they are worth it! Maybe they are not... But why compare the price of a Giesemann pure actinic? 1. Entirely different bulb spectrum. 2. You can find plenty of pure actinics for $10 - $15, so I wouldn't buy the Giesemann one either! Almost every brand out there sells pure actinics at 420 and 460 for much cheaper than Giesemann! Have a look! Although I do agree with you that it is nice that the UVL actinic bulbs have internal reflectors, solid reputation, and still hover around $20, so these are probably worth it when purchasing pure actinics!
Yep, he's a published author, and his pic is titled "giesemann fiji purple.jpg" and he states that he has no idea where he got the graph...
http://www.practicalcoralfarming.com/t5spectrums.html
It is clear that other sources of this graph have simply ripped it off this same article... Read these articles, and look at the file name! In all the examples (except for the reefgizmo one), it is still called "giesemann fiji purple.jpg" I guess one guy had the sense to notice and change it! LOL But this same guy also actually tells you upfront in his article that his data is coming from
http://www.practicalcoralfarming.com/t5spectrums.html... And the last example is just a blog wherein the orignial practicalcoralfarming article was simply copied/pasted in its entirety! All of this hardly makes the argument "at least they are the SAME" hold any water... The graph is not very specific, either. The whole thing looks like it is mathematically averaged between very few data points... Look at how soft and curvy it is... there are no specific peaks jutting out... What kind of light emitters do that?
As far as email support goes... I have exchanged emails with Current, Wave Point, Aquatic Life, UVL and Korallen Zucht all in the last week, and every single one of them except for Korallen Zucht has been helpful, and provided me with specific nm peaks and spectrum graphs. So that is how many times I was able to get assistance from someone over email support...
Anyways, I'm interested in reading more about the benefits of 700-800nm during flowering that you mention... Can you help me out with any links to get going? Cheers!
thanks.
