Jeg har nu modtaget svar fra
http://www.talkingreef.com på mit spørgsmål om hvor mange 250 watt HQI lamper 72" modulet svarer til.
Det ser ud til at 72" systemet svarer til 3 stk. 250 HQI lamper.

Olsen,
Knowing Pat would be busy getting ready for his trip, I emailed him last night and asked him your question about what MH fixture would the Solaris fixtures replace.
He responded, each size Solaris replaces the equivalent MH fixture.
So the answer to you're question above would be a 72" 250W 20K Solaris fixture replaces a 72" MH fixture with 3 250W MHs or smaller wattage. That would hold true down through the other sizes.
That's what I thought the answer would be but, I wanted to give you facts rather than conjecture.
As far as advantages, they are;
1. 40% energy savings over the equivalent MH fixture.
2. Adjustable color temperature from 6.5K to 20K.
3. Computer programmable for sunrise, daytime sun, number of cloudy periods per day, length of cloudy periods, sunset, moonlights, moonlight relative brightness, moonlight length, darkness, moonlights on just before sunrise.
4. On automatic, unit is set to coincide with current sun/moon phase. Simply set the date and time and it is preprogrammed.
5. Bulb life of 50,000 hours minimum.
6. Four computer controlled fans for cooling.
7. No heat transfer to the aquarium.
Pat, an engineer under his employment and an engineer in China, worked for two years getting the Solaris units to market. He has $100's of thousands of dollars invested before the first unit was sold.
While the Solaris units are expensive I figure they will save you the difference in price in a short period of time. I don't know how long it would take but, *is there any MH unit that can save you anything?* I'll let you decide that one.
Hope this helps clear things up.
