How many of you have went back to halides or t5s

Copy and Paste:
"Light Emitting Plasma™ and Light Emitting Diode (LED) provide similar reliability and lifetime...Lumen density of LED’s is still low compared with Plasma. It still takes about 100 typical high lumen LEDs to produce similar lumen output to 1 Plasma source..."

I was reading about this on AA.Very interesting.wonder when we will see it states side and not over price

LEP is being used in a public aquarium in Ca. I think it is originate in US.

Officially the first time I have heard of an LEP and I must say, that's intense. No pun intended.

pay no regard to the the man behind the bryopsis

edit: currently raising mag to 1600 :/

edit#2 : color on red caps a bit more striking in person.....underwater photography....phsssh

As dar as LEP is concerned... there's def more energy consumed..there's an awesome article in advanced aquarist, BUT if you read the results on each comparison. it seems higher end sps are the only winners

Higher end SPS is what I like. Once you go SPS, you can't go back.

Halides baby!!

Wow, that was rather rude to say..

Anyways, not all of us have $800+ to blow on a camera, and many of us don't want to.

And remember, T5s and MH didn't have a proven track record when they were new either...

No new technology is going to have a proven track record of long length obviously. I'm saying a year with LEDs in the pico with great success and half a year in my 40g with great success.

Many others have had great success.

Holy crap. Did I say MH/T5 has a proven track record when it was new? Proven track record and new should never be in one sentence. Reread my post and think about it more.

Don't be silly Dong. I highly doubt the sunroom contribute a significant amount of light into the tank. If he's using solar tube, okay. But not from ambient light just because it's in the sunroom.

Have you seen his sunroom? It let's in a pretty serious amount of sunlight.

And it's been proven that a tank near a window grows algae quicker.

So you're saying sunlight from a window ("ambient") can grow algae quicker (known fact) and yet somehow that same sunlight won't affect coral growth?

I know you said "significant" and I do suppose that is debatable, but even if ReefKeeper2 has all his lights off during the day, I can promise you his tank will still be lit rather well from sunlight directly as it passes overhead.

when did people become so sensitive?

I dont want to speak for Dong but if I were to guess what he was refering to in regards to the sunroom comment is that in many's opinion LEDs lack UV and a certain wavelength of light...the sunroom's ambiant light fills that void.

You are right, the sun is too dimm to support coral.
We need red, green and blue laser beams and a disco ball.
jk....
and...welcome back.

Reefkeeper2 's tank is in a SUNROOM, his LED are just supplimental lighting for color.

What Dong said is exactly the opposite being the LED is supplemental light to the ambient sunlight.

Hahahha. Disco ball. That's another disgusting side effect of using LED with a narrow beam lens to get the higher intensity. The newer fixtures like Pacific Sun ditched out the lens and there's no disco ball effect. They're moving the right track at least.

 

[dz6t]

Well, I have a cheapo eBay LED without any lens (too cheap to put them on) and still have disco ball effect.
I think it is the use of fewer higher power LED chips and space them too far apart cause the disco ball effect.
I have a fixture use 1 w LED chips and there are 120 of them jam packed in the same foot print and it doesn't have disco ball effect.

Agreed. Good quality LED and good design will be the key for LED to be successful in this hobby. The Triton Lani is a good example. They use top bin 1W LED in their fixtures. Expensive as heck though.

Many people think they just throw a bunch of high powered LED and expect it to work but end up in heartbreaks.

 

[dz6t]

yes, the Triton (Germany) panels are very well designed. There is a little know fact that 3x1w LED generate more light than a single 3w LED. Higher wattage LED is less efficient.
This Triton LED should not be confused with the other LED also bares the name Triton.

well then I would disagree and believe that the AIs do more than just supplement the sunlight...Id think it the otherways around. But thats just me.
