How many times was that bulb cycled in that lumen maintenance chart as well. Everyone knows startup is what causes lumen depreciation.
I posted what I saw from another forum. Take it or leave it. Do you see that I posted the guys name and all that? He works for Nanolux. We are arranging with a commercial grower for greenpower bulbs to be pulled at 3,6,9 and 12 months to see if what that employee says is true. Lumen maintenance has no use here. I have personally tested bulbs with a radiospectrometer and saw color shift with my own two eyes. I have tested a DE that was about 8 months old and compared it to a new one and I can confirm with a certainty that the spectrum was indeed different.
Do you have proof that what the employee stated is false? I'm not saying it's true either but I'm not calling you a liar like you are me.
I could've as easily posted just what he said instead of the pic. Why did I do that? Because I was making sure that it wasn't my statement. Just brought up curiosity in me is all.
If you think for one second that companies like Gavita won't bullshit you, you are nieve. I've sat and watched one of the owners of Gavita tell people there fixture is 2100 umol output on the 1000 watt setting. As a matter of fact he told me that. Well we all know that's not true. They are 2100 umol at the bulb. They are 1850ish coming from the luminaire.
Now that you've went out of your way to call me a liar post your sphere data showing the UMOL maintenance of a DE fixture over the course of a year.
Also follow this link to sphere results of DE fixtures that where seasoned for 100 hrs. I've seen numbers in the 1850s brand new. So why the discrepancy?
I still call it inconclusive at this point. Lighting laboratories don't lie as far as I know. Unlike most we are going to put up the thousands of dollars it takes for these tests to be done.
I honestly don't need to "sell" our product to anyone. We are sold out have been and will be. Kinda stupid to try and drum up buisness that we can't handle don't you think? I'm here to learn and for the education myself.
