Harrad said it pretty good. Lumen per watt is same for 1kw HPS, but not overall intensity (ex. 1kw HPS puts out 126,000 lmns. new, and the 65w Flourex putting out 8255 lmns. new--not including ballast lost) which the 1kw HPS clearly wins. Umm.. did I double post? Hope not
"Born0420,
Good Info! I am going to offer some minor corrections and additional suggestions if you bear with me.

That's 127 lumens per watt, which is BETTER than the lumens per watt produced by a 1000w HPS, which puts out only 114 per watt

The chart you quoted lists the mean (average) output of a 1KW HPS at 126K Lumens, however as presented the FluoreX output @ 8255 Lumens is for a new lamp. Actual output on a new 1KW HPS is 140K lumens. That puts BOTH lamps with ballast losses included at 127 Lumens/Watt new. Just got to make sure your comparing apples to apples!
