If you have followed the course of this thread you may have viewed comparative data collected by beachcomber that included a spectral distribution chart showing the performance of each of the lamps which was quite revealing as to how they each perform in real life. More then one document has been posted outlining what the ideal spectral response of the lamps should be so determining which lamp lies closest to the reference plot should have been quite easy for even a lay person to deduce.
You state that you feel that Ideal Lume products are superior due to build quality and versatility! Ideal Lume is a turn key solution which provides a good option for a number of users to turn to. The actual performance of the lamps being sold which Beachcomber tested are sold in most cases as a "lamp only" requiring the user to supply their own fixture, ballast etc. Beachcombers conducted tests strictly on lamps where I find it very difficult for you to make a claim as to how much better one lamp is over the other without performing extensive testing.
It seems that you will not believe the test results unless Price Waterhouse or some other accredited independent firm oversees all testing as well as the handling of the measurement data. Please specify exactly what is required for you to find any test data to be accurate and reliable. The data provided seems to be acceptable to the majority that are viewing this thread.
It would appear that beachcomber is correct that you are unwilling to accept scientific fact as his testing data is quite conclusive and quite scientific as well. Very few users on this forum have a White reflectance standard which to measure the light from the lamps properly with let alone a high spectral bandwith and high resolution spectroradiometer.
You can say it as many times as you wish, but it won't make it true. You have no way of knowing if his test results are valid. You do not know for a fact if those instruments were used and/or used properly. You are simply taking his word for it and nothing more. I do not question the accuracy of your product. I question the manner in which it was used...if it was even used at all. No one was there to validate these results. I have been give absolutely no reason why I should trust these results.
My opinion about the ideal-lume was posted before his claims were made...not after. My opinion has nothing to do with his "tests" or claims.
His results are conclusive only if you trust the manner in which the tests were conducted. Based on his conduct within this thread and others...I have no reason to. Again, he has made other claims as well. Claims which were not based on any evidence and he quickly slipped away once he was proven to be wrong without ever acknowledging it. It's a simple pattern of behavior. You must keep in mind that when I stated my opinion...I mentioned nothing about the 6500K standard. That was BeachComber's assumption and he decided to attack without taking the time to review the situation. Again, a pattern.
Yes, I believe that the Ideal-Lume is superior based on build quality, versitility, and other such factors. You point out that he tested lamps only. I'm well aware of this. I stated my opinion independent from his claims. My opinion had/has nothing to do with his claims. My opinion was not only about the lamps, but the entire product being offered. You would have been aware of this had you been involved in the conversation. You were not and seem to be here because he cannot defend himself. I am more than welcome to my own opinions...as are you and BeachComber as well. The problem arises whenever he attacks me for having an opinion at all rather than proclaiming his opinion to be absolute fact.
You're defending someone who has done the following: Sought me out in other threads regarding very different topics...having nothing to do with bias lighting...only for the purpose of attacking me for not agreeing with his opinion. He has done this more than once. In this situations he does not attempt to discuss the topic at hand, but instead focuses on attacking me. I am the one who has attempted to offer an olive branch serveral times and I have been turned down each and every time.
The bottom line is this, I believe that we should all be free to have our own opinions and be comfortable with our very own buying decisions. BeachComber seems to believe that his opinion is the only one which matters and any purchase he does not agree with is rubbish. That is the behavior you are defending.
