Not everyone runs MH and not all MH, at say 400 W, necessarily produce the same amount of
light. As I said, you must of missed it.


EFFICACY = Lumens / Watts

All one has to due is look at any 400 W MH and compare it to 400W Iwasaki. No MH @ 400 W
even comes close to this bulbs light output.


"then you would say "It doesn't matter".

I never said it does not matter. Do not be putting words in my mouth :-) It is misleading.
I said "A 400 W lamp or 40 W lamp says nothing about how much light it puts out of any
kind". . Almost any 175 W MH will _usually_ but _not always _will have more light output
than say a 150 MH

OK Wayne thanks but I don't have them or can't see them :-(

The problem is that it estimates how many lumens of light in the eye can see. The shortage and what is considered conducive to coral. For example, a large amount of sodium lumens of light, but too yellow reef tanks.

A 400-watt or 40 watt light bulb in the amount of light put out a silent any kind. Most lamps use power to drive themselves. An average of about 75% of the electricity is carried out its other 2% will be more effective high-tech materials some readers the light output.
