gbru316,
I am well versed in science/physics. But let's stick to the facts. Your paying outrageous prices up front to save very little down the line. So, in fact, your NOT saving anything.
YOUR LOSING MONEY. Not saving money! And many here will tell you just that. They have lost BIG MONEY. And they will tell you they are not happy about it.
IF their cheaper to manufacture, then they should be sold for less. Not astronomically more.

wattage means nothing. A watt is merely the amount of energy used. It's an incredibly poor, if not inappropriate, way to compare lighting sources.
A watt is nothing more than the amount of joules used over a period of time, usually seconds, which has absolutely nothing to do with quality or amount of light.
If you want to talk about efficiency, you should be concerned with how much light is produced for a given watt, because a significant amount of power, in most lighting sources, is wasted as heat.
Watts to lumens produced.
LEDs have recently been able to "get close" to fluorescent lamps. still alot left to do![]()

And Jim, That's one of the best energy savings I have heard of so far. How many T5's are you running? Why T5's on the tank?
Thanks
My favorite part: people bashing LEDs who have not used them, for whatever reason.
LEDs work, if you don't have success with them, there are a few scenarios:
1. You are doing it wrong
2. You wouldn't have success with a reef to begin with
3. You are doing it wrong
4. You bought the wrong fixture
5. You are doing it wrong
6. You built the wrong fixture
LEDs make corals lose color when they are not at the right intensity and/or spectrum. Adding pink/red LEDs help bring out those respective reds and oranges. UV helps add color too.
You can't convince me of any of the claims here that are not circumstantial to improper use or application of LEDs; whether that be intensity, spread, and/or spectrum. This is not from evaluating others experiences alone, it's from my own first-hand experience. More often than not, when someone complains about 'LEDs not working', there is an explanation for it such as lack of spectrum or running them high. LEDs at 100% is very very bad, for the corals and the emitters themselves. In a worse case scenario, optic-less emitters can be run at 100%, but you will lower the life of the emitter as well as increase heat output, which can possible shift the output spectrum of the emitter. I know this, from experience. Although, I adjusted the current on that fixture to only hit 85% max intensity (600mA).
I've never used MH, so I can't attest to either one working better than the other. What I can add is that LEDs do in fact work to grow coral and produce vivid color and visuals, when executed appropriately.
to further elaborate, I don't think it's feasible to build a LED fixture that works for everyone. There are many variables that do not need to be considered for traditional, omnidirectional light sources that are critical for adequate LED performance.

rrasco,
My grandpa and dad taught me this long ago. I teach my kids the same:
1. Learn from your mistakes= SMART
2. Learn from someone else's mistakes= SMARTER
I value everyone's opinon here and always try to learn as much as I can. Let me put this scenerio out there for you guys. Its a guy lets just say I know......LOL
36x18x24 reef tank. 65 gallons. Center rear overflow.Tank will house SPS corals. Lagoon zone. Currently he's useing a 250 watt Lumenbright fixture with 14K Hamilton bulb over his smaller tank.
Choices:
1. Purchase another 250 watter to add for the 36 inch length? Total 500 watts
2. Purchase a 6 or 8 bulb ATI T5 fixture. Total 312 watts
3. One Maxspect Razor LED. Total 160 watts
4. Two kessil 350's. I think those are 90 watts each. Total 180 watts(correct me if i'm wrong)
So look at the differences in wattage. and I am sure heat will be a substantial difference. He has a chiller, so he can manage the heat issue's and plan to use it regardless of which lights he go's with.
Halides: Now, he could run the 2 250 watters probably only 7 hours a day and a actinic T5 for the rest of the time. Or a led blue strip or some other solution. That would afford him 1.5-2 years on the halide bulbs...........
T5's: 8 bulbs in ATI fixture is bright. Maybe 1.5 years on bulbs before changing them out.
Led's: substantial heat and wattage difference. Will it be enough light? 500.00 investment.
What do you guys think?
What is being said is that MH's work BETTER as far as growth and coloration and many of us have seen this first hand.
I dont think anyone in this thread is disputing that LED's work. What is being said is that MH's work BETTER as far as growth and coloration and many of us have seen this first hand. I grew SPS under AI SOL Blues for 2 years and was far from impressed compared to MH systems. I don't think it because we are doing it wrong as you state, I think it is because some of us have actually used both styles and prefer MH to satisfy our own tastes.
bhazard, have you done any work on a DIY fixture with a build thread? I'm very interested in seeing what you come up with![]()
