Hello,
So there seems to be frustration here in what or how things being sad. In my post
@jda i said to be honest and professional it was not a personal attack. Further more testing in lab environments and testing lights in general will vary based on how the experiment is set up and how the tester conducts said experiment. You saying that it’s impossible is gross exaggeration. If these lights are so crappy as you claim which you have, then explain why sps, and a Maximus clam donas well as they do? The clam is 24 inches down and getting plenty of light so clearly it’s not a lack of light.
All of my testing that I have done was when I attended university of Washington. In our lab experiments yes we caliberated them several times per day. We had others use the same par meter and took the average of three tests. It wasn’t a simple look I’m at home and having fun. The problem is you claim they are terrible but you simply can’t say why. If you have experience, then what experience do you have with said lights. Since you can’t stand them, why on earth would you experiemnt with them in the first place?
I never said all of them aka current usa lights were fabulous. As a point of fact I have said several times that the ic loop version and first version lights probably wouldn’t do great with sps or clams. The model version 4114 that has a 60 degree lens is much more concentrated that a 90 or 120 but I’m sure your aware of that. You can also account for critical angel, sin/cos of the angel of light, and of course turning off the wave makers. In my experience nothing is impossible, the lights I am speaking of have been consistently underrated. Again if they are soooo crappy and it’s impossible as you stated how is my coral growing in my tank which I have shown? I’m pretty sure it’s not based on luck.
So again as you stated make sure you get all facts as well because your missing several of them as well. At no time that I have come across (the ones I’m active on with you) you just say they are crappy buy something else?) well which ones are crappy, why are they crappy. Sorry to say but there really isn’t much difference between Ecotech, kessill, current and other led manufacturers. Most of them get there leds from the same manufacturer.
Yes there is mixed reviews between mh t5 and leds on what’s best and experimental with all of them. Not once have I said leds or better or this or that. I have said because they are living animals, that drastic changes in thier environment could have negative consequences, yet could have positive ones also.
In addition to experience, granted yes I don’t know, but you don’t have any idea of mine either. In sense I have way way too much time in lab, and hoping that I do much less of it in the future lol. Based on your comments and posts, you say current usa can’t grow corals you will be unhappy get this or that etc. Well my tank is 13 months old using these crappy lights. So maybe the crappy lights grow coral just as good or better than the exotic Ecotech, or who knows what. At no time did I say you had to change your opinion or can’t voice it. But when you have, you haven’t really given a reason other than they are crappy, (in the posts that I have seen, you may have others that I haven’t seen or been part of).
As far as we have been over this? What did we go over, I have not had any such debate or even conversation in detail about it with you. So when you lay it out and want facts I guess it goes both ways, or am I missing something?
@Foothill Corals yes your correct on that information, I was only aware of certain models. We used several of the ly-cor 1500 data logger so we could log information and if memory serves me correctly we used the 190 quantum sensor and then moved it to give it different angels, where we have found the critical angel as well. In double checking or work we also in conjunction used the light meter 250a from ly-cor as well where we have to calibrate them.
But you correct, that they did have some sensors that were off but I was made aware of that with the ones we had, I was a student st the time lol why would they tell me. Knowing my professors they probably knew and laughed at us wondering why nothing worked or came out as predicted. I have only usd an apogee once which my local aquarium had. I have not used that one in my tank, but did use the same procedure on my tank as well. Did they vary yes but not by a lot, or enough to warranty a re test or that we had faulty equipment.
The point is, we all have our opinions about anything in this hobby. But to be honest, telling Someone their light is crappy (even if honest) doesn’t really help. So what does help? I don’t know maybe some positive reinforcement and ways to make what they have work and or how to supplement something into that to make it better. It’s easy so say your light is crappy go buy an 800 dollar Ecotech problem solved. Most people don’t have 800 dollars times how many they need to do that, even if it’s hydra, t5, etc etc, they are all about the same price.
Another aspect is if these silly expensive lights are sooooo perfect, why don’t aquariums use them? I have yet to see any major one (well on the west coast and only been to one on the east) use them? Their tanks are amazing and much larger than what we have (mostly). They use current usa they use Chinese black boxes, mars aqua etc and mh and some t5. It’s sooo random spin a wheel and pick something in all honesty. Some people are not as fortunate as others and let’s be honest my lights are 809 each. Did I pay that much (no) I was asked to test them, and they were donated to me by current. (No I’m not a sponsor, no I don’t work with them, and yes at the time I was a student doing my thesis). Do I think they are thee absolute best brand no I don’t, do I believe they make good stuff yes. I have had tremendous success with the items I have yes.
For my tank being 13 months old total I have tremendous growth. I have pics posted here showing, even in my thread you can see where they were tiny little guys and now they are five times the size or more. Have I killed some yes, but who hasn’t. For the record I have never said they are the best and all that. I have only said they are not crappy, they will grow coral. Ripping all the lights off and spending 800 plus does nothing but deplete ones bank account. If they want to great it’s their money, but it doesn’t mean it will solve their problem. It very easily could, and very easily could give them a whole new set of probelms.
Again
@jda I clearly stated to be honest and professional, I said that so one would not take it personally. It was never meant to be personal, I was meant to be professional and when one is professional they are asking, if these lights are so crappy and won’t grow well why? What are the reasons, anybody can say they are crappy or great. That’s all great but can you clearly explain why they crappy? Just because they are not name brand and 800 dollars doesn’t automatically label them crappy. Other have also stated they are crappy when we spoke they had zero experience, had never owned one, they say oh just buy a radion. Have you seen how many people have issues with them, or others? Chances are most companies are going to have probelms it’s actually normal.
Other shows pics of their hybrid radion and t5 combo and my forest fire digi looks the same and I use crappy lights. So I’m not sure how my coral grows, but pretty sure it’s not the lights. These pics are taking with my crappy iPhone with normal lighting. This is not solid blues as for the point my cool whites are about 40% and blues at 100.
