Must be those people who thought the dress was white and gold. Losers! :lolspin:
He means that most users don't turn blues down on their LEDs.
lol if you could afford multiple radions I highly doubt u care how much money u are saving on your electric bill.
I cant run mine that high, Things start to fade out at 75% intensity and thats only with white, green and red at 45-50 % the other three slides are at 100%. There seems to be sweet spot about 60-70% overall intensity and the slider for K at about 14000. Thats just my observation though.
Yes, thanks.
In response, he's still using LED to replace his MH setup.
So if you were using 250w mh before, sure I guess you would use less power on your LED's. You still need the same amount of units IMO to get the same light spread/coverage.
So it should be pretty relative and the energy savings should be pretty similar either way.
I don't think you would need twice the units to replace a 250 mh but figure for a 24x18 coverage, not the 24x24 or 30x30 the manufactures advertise. I could see it taking 2+ units to replace a 400 watt mh.

Coverage of a 200 vs 400 is the generally the same, using the same reflector, no?
The problem with LED isn't the intensity (usually) but the spread.
Which is why I believe "twice as many" is the best way to go.
So if you have a tank that is 6' long, the manufacturer would probably recommend three across. I would say ideally 6. Might be able to get away with 5.
At least that's what I would do if I was going LED again.
I would do 3 or 4 depending on how I would scape. Keep it low and flat allows light to spread. Steep and tall is a challenge due to the point source nature of LEDs. If the scape is tall and steep it might take more to adequately light. Just one more thing to make LEDs more challenging.
It seems to be a common misconception that MH automatically equals chiller. This is not a case for a lot of people. I live in the midwest, and have never needed a chiller.
Most of the people I know that have MH have never needed a chiller.
My tank sometimes will hit 84 in the summer, but that has no bad effects. It also gets that warm in nature on natural reefs.
Everybody's situation is different, but its definitely not an automatic thing.
Yes, and thats one of the cornerstones of a lot of pro-LED arguments too, they start immediately factoring in how much electricity a chiller uses as if its a given. With a proper set-up, MH do not require a chiller.
