corals and LED light.

Your acros didn't die from your LED's. They Died from not enough LED's. 2 strips will not replace 400w MH.

 

nicely put, leds are very expensive and not near as powerful as mh

 

i said a panorama fixture, Panorama System | Fixtures | PetSolutions these are several strips in one, i repeat metal halides are much more powerful than any led's just no argument there.

 

There is an argument there that I don't have time to get into now, maybe later little one.

 

LED is a great lighting alternative for fish and low light coral only tanks at the present time, however, they do not (1 to most 2 watt values even some 3 watters) have enough PAR for most large tanks due to the PAR requrired for good health of said critters.

When you compare the required PAR vrs. MH, LED fails to provide enough light at a given depth (PAR) that most critters require for good long term health. I really wish it was other wise- for if it were so I would own them. The benifits would be vast to say the least.

 

one for one yes....but 400W of cree LED is going to produce more light than 400W MH. how much of that light cant really be used is still in question.

 

its just unrealistic, who would pay twelve hundred dollars for a light fixture that has less output than a 400 dollar light fixture.

 

dollar for dollar, not watt for watt... leds produce more usable light per watt, but also cost a heck of lot more per watt. just clarifying...

 

there is no fixture with 400 watts of led, that would have tons of lights since leds normally have lower wattage with more light.

 

How many 400w MH bulbs will you have to buy in 10 years?
