If it really is close to 75, one would think they would not be shy and call it 75. Are you actually measuring the lumen output or just "eyeballing" it? Do you have higher than 'normal' line voltage? Not pickin' on ya, D.P. It's just that inquiring minds want to know why the difference. :-) On 8/10/2013 7:46 AM, D. Peter Maus wrote: Dial it back, Joe. I did mention that I used a light meter to measure the output. Were you not reading? Yes, I was reading and here is what you said, input, not output: First blush, nicer, more color accurate light. And, using my light meter, more of it for the energy input. "...using my light meter, more of it for the energy input"? Maybe my bad or maybe not. Your grammar is a little convoluted and it really isn't very clear (to me at least) what that statement meant. To most people, energy *input* refers to the 8.5 watts the bulb draws from the AC line, not the lumen *output*. You further state: I'm at the beginning of these lamps' life cycle. So output is higher than rated. It would be interesting to see if the manufacture has a graph that shows lumen output versus hours of operation. |
