JNB you do not need to "run any experiments", as I stated, we can do some fairly accurate calculation without ANY of that data.
All we really need to know is what wattage you had and how many hours a day it ran. We can compare that to the new lamp and how many hours a day it runs.
Seeing that your AC unit and Chiller were built in the last 50 years, we can make some pretty good assumptions about their operation.
I illustrated earlier that modeling the MH setup as a 100% heater and the LED setup as a non heat source will still not generate that kind of difference, even with the AC and chiller running inefficiently to remove the heat from that 500W MH 'heater'. In other words worst case still does not generate that much of a difference between before and after energy usage.
I do not feel you are being dishonest or trying to exaggerate. I also do not feel like you are trying to mislead anybody. However, I do feel that you are been as confrontational as possible with regards to my posts as well as having ignored the information that has been previously provided and posted. I feel that you and several others are more concerned with conveying personal feelings than you are the truth.
I have offered to help you and others understand the energy consumption and possible real world energy savings of these devices. However, you and several others have chosen to either ignore the information and/or professed not to care. In both cases that is your right.
However, as long as misinformation is being conveyed (on accident or on purpose), I am sure somebody in-the-know will step in to clarify it.
You have added value to the thread with your personal experiences regarding the look and feel of the fixture and feedback on its operation. However, you can not just assume that your personal feelings and observations, and those others that YOU agree with are the only items of value.
A small group of you who thinks somewhat alike has decided that this is YOUR thread and only YOUR information is worthy of comment. That is unfortunate.
Instead of looking at everything as an arguement, you guys may want to try to approach it as a conversation.
