4 lumens per watt extra is pretty minor and you have to take into account the fact that, the ballasts also draw some power. When I was planning my most recent space for example I was debating two 600w vs two 1000w. My 1000w lamp is rated at 146,000 lumens a 600w 90,000 lumens. So 2x 146,000 = 292,000 vs 2x90,000= 180,000.
That is a big difference! Two thousand watt lamps put out 112,000 more lumens! Two 1000w lamps equal more than THREE 600w lamps!
So how in the hell is a 600 watt lamp "more efficient" than a 1000w lamp?
Like I said before it is Jorge Cervante's bullshit . . . .
True but a 1000w lamp is almost TWICE as intense as a 600w lamp. That is a big difference.
The cool tube comment you made is silly, the glass of the cool tube refracts a minor amount of light if it is good glass and the cooling benefits FAR outweigh the light loss.
So there you have it I'll stop hijacking the thread now, sorry peeps post your

No one said how much more efficient they are..
Nothing was said about cool tubes reflecting.
And of course 2 1000s are more than three 600s. We can add.
You have clearly missed the point.
