Kissman, one more thing and don't take this the wrong way, but after taking part in your other thread titled "help with sps color" which had 539 posts, I probably wouldn't go led if I were you. They will add even more instability to your reef. If you had sps issues with t5's, trust me, you will really struggle with LEDs. And to your comment on $120 bulbs every year, you will still save money since LEDs are so darn expensive to start and my ai's, and ecoxotics both had LEDs go bad almost immediately. I do disagree with your time period of one year though, I would change your t5's every 9 months at least.
Curious how the AI sol are so bad, my corals dont seem to agree
and now with 300 watts of led replacing 1600 watts of halides plus 220 watts of actinics my electric bill is a little better as well. Visually its not quite as good but looking at the financials the leds are a no brainer if your in the hobby for the long haul.
Sol blue-They are not the cheapest or most expensive, but they do work and can penetrate up to 4 foot depths which might not factor into a 55 gallon tank but since they are small they can grow with your setup.
Whatever led's you go with , be careful to ramp the power up slowly , you will be surprised how much par they can put out and not look extremely blinding like 400 mh's can.
Who is trying to replace the sun? Have you seen what the sun does to coral colors? The last thing lighting fixtures are trying to replicate is the sun. :lol:I'm sure it's only some species, but it just reinforces the fact that led's with nothing else, is not acceptable for replacing the sun.
You really don't save any money. $120 on bulb per year is a ton. And if you buy an AI sol or something, that's your fault. AI fixtures are far worse than their competitions. I guess the Vega is okay with the programming, but this cost a lot.
Ecoxotics have been known to fail as well due to heat and just overall bad design. I think the newer ones address the problems a little, but you still have to keep them well-ventilated or open-air.
Go with a fixture from Reefbreeders, Maxspect, or maybe Ecotech. Those are the good LED fixtures you can get off-the-shelf.
The Mitras fixtures are way overpriced. $1100 for 190w doesn't scream "good deal" to me. Just buy a Razor.
When I bought my ai sols almost everyone here at reef central were raving about them. They had just come out with the royal blues and I was hard pressed to find an unhappy review. Boy, a couple years down the road and now it's rare to find a positive review. I dropped $1400 on three fixtures. If I was to buy 3 radion pro fixtures at $900 each, that's $2700. That would be a lot of $120 bulb replacements, what maybe 20 years or so. Currently I have a wavepoint t5 4 bulb fixture with ati bulbs. Everything in my reef, including sps are super happy. My wavepoint fixture was $245 out the door + $90 for new ati bulbs. There's also electricity. My ai sols were around 70 watts each. That's 210 watts. My wavepoint fixture uses around 230. Not much savings there.
I not trying to be a pain, I've just been there and done that. I do have to say though, if LEDs came way down in price, I might give them another chance. For me, they would have to be priced comparable to a standard t5 fixture, which "I" know for a fact will grow any coral I put under it.
The thing is the time-frame. Corals bleaching from too little light doesn't happen instantly. Some instances, where it happens over a long period of time could probably be too little light. There are plenty of these cases out there, where things deteriorate over the course of weeks or months. But when people talk about LEDs "cooking" their corals, they usually mean relatively quickly, days. Corals can go without light for days without a problem, so odds are a coral bleaching out right after the LEDs go on is from too much light.I've found a coral can bleach from to much light or not enough, so I don't buy the whole "LEDs are cooking" the coral.

The key tidbit of info I found amusing, the fact that some corals DIED and NONE survived under LED's.
I'm sure it's only some species, but it just reinforces the fact that led's with nothing else, is not acceptable for replacing the sun.
60* optics are good for up to around 30". And you can always switch out the optics for 45* or 30* ones.Asid, please explain how an 80 % monthly power reduction on lighting, and side benefit of less evaporation so my 800 watt dehumidifier runs less is not really "saving any money" not replacing 4 $80 bulbs every 9-12 months, the lights pay themselves off in 4 bulb changes while the whole time the power meter spins 80% less. the 5-10th bulb changes come out to free..... take a look at the total cost of ownership
penetration depth is largely dictated by the optics in this case the ai sol using 40 and 70 degree optics,,, many fixtures use wider optics like 90 or 120 optics on 2 watt bridgelux bulbs, which works in shallow tanks very well. I have a reefbreeders chinese led it works fine, but it does not even come close on par numbers at 36-48 inch depth. the cheap chinese blue leds seem to last, but the white ones dont have the same coatings liek the higher end cree bulbs, so would not expect them to last as long.

One of the things to keep in mind is the availability of parts or service to your LED unit a couple of years down the road. The theoretical lifespan of an LED at 50,000 hrs is total marketing bogus. LEDs, circuit boards, power supplies, fans are failing in LED fixtures all the time.
I have zero confidence that if my power supply burns out in four or five years, or if some LED burn out that I can get the fixture repaired or be able to buy a replacement power supply, etc. from the manufacturer with the Chinese made fixtures like Reefbreeders/Evergrown or Maxspect for example.
I guess it's my background in engineering coming into play in my decision. Some factors I considered in my decision:
a) US made company (not a US importer)
b) Personal level of service
c) Simplicity of design - more electronics and moving parts like fans, more change of unit failure
d) Light spectrum
e) Ability to dim, ability to interface with a controller.
Based on these factors I went with a 36" Build My LED - Custom Reef Spectrum fixture. I've had it a couple of weeks over my 50g reef and could not be happier with the light (running it at only 60% brightness), it's quality engineering (waterproof and with unique rotatable tank mounts), the personal service I received in getting advice before and during purchase, the 3 year warranty and my confidence that I'll be able to get parts or repairs out of warranty from this Texas USA company.
Best of luck with your decision, just some more things to think about, irrespective of which LED fixture you go with.
