My new 450 Gal "pail"

What are your thoughts on the ability to dim LED's? The orpheks make one of the nicest LED units to date, but surely theyd get alot more people purchasing them if they had the ability to ramp up and down.
 
Absolutely stunning. Tagging along for more knowledge from this thread. I signed up because I wanted to post in here! lol... Keep on updating and I'll keep on reading! :)

I consider the dimming a nice gimmick. I will not recite the manufacturers explanations but I don't even have the chance and time to enjoy the dimming since I'm not at home at least when "dim in" starts.
It has no advantages for corals what so ever. I never used this option with the metal halide system nor T5 so I don't need it.
If it was a part of the setup, it could be nice but not more than this.

Thanks Necidemos, I'll try to keeping happy :bdaysmile:
 
You just keeps us updated on those lights. That was a big investiment and I'm thinking about doing the same thing on my 210g. I just need a little nudge to buy them is all. Keep us updated! :)
 
thanks, yeh im in to worlds about dimming control. ATM theres no hard evidence that dimming is beneficial for corals and fish. Have you seen any other LED units in person? and how did they compare to the Orphek?
 
Hey Bro,

I have so many questions about LEDs since you are pioneering in this new technology...
1. How did you decide to choose that specific LED company?
2. I heard that you can decide on how many blue vs white LED bulbs you get per fixture (why did you choose .3 to .7)?
3. What does the 90 degree thing mean?
4. I'm thinking of building a 600 gallon build 96"x48"x30"tall...how many fixtures and what degree (60 90 120???). Just thought I'd pick ur brain!
 
Thanks guys.

I have so many questions about LEDs since you are pioneering in this new technology...
1. How did you decide to choose that specific LED company?

I saw the fixtures on my friend's tank. I liked the colors, the coral's reaction to it and the look of the fixtures.I inspected the technical info' and I was convinces to test it on my tank.


2. I heard that you can decide on how many blue vs white LED bulbs you get per fixture (why did you choose .3 to .7)?

I heard so too. I chose the basic version since I've seen it and been satisfied enough. I don't like too much blue or artificial light and coral reflexion.



3. What does the 90 degree thing mean?

90 degree means that the spread of light is not wide but penetrates deeper. Since my tank is 34'' , I decided to use the narrower lens.


4. I'm thinking of building a 600 gallon build 96"x48"x30"tall...how many fixtures and what degree (60 90 120???). Just thought I'd pick ur brain!

for this wide tank I'd use 8 fixtures if you plan growing SPS corals.

Have you been able to compare the output of the LED lighting to your old lighting or any others with a PAR meter? It would be interesting to know what you are getting in the real world on these fixtures.
 
Hi Bmco

I noticed your tank is used in the orpheck promo photography for the new DIF100 Multi Chip LED Pendant.
I have been considering using a couple of these as supplimental lighting to highlight certain corals.
At the moment it is a toss-up between the orpheck or the cannon led pendants. TBH cannon are edging it for me due to the swivel brackets.

Can I ask your opinion on the orpheck led pendant lights?

I tested Par with the Apogee Par meter.
The results were:

Under the white\blue led - over 3000 Par

water level (12'' under fixture-out of water) 1250 Par.

Top water surface - 950 Par

5'' in water 820 Par

Tank bottom (35'' under the surface) - 250 Par


I must say I'm pretty impressed.
 
aandfsoccr04 thanks for your kind flattering words :dance:

Do you need it for extra blue/actinic look? If you do, I must say it has a great look. I'd like to use one more unit for my 95'' long tank.
As for the comparison to Cannon fixtures, I can't add my opinion.
The effect of the DIF100 Multi Chip LED Pendant is more spread than other led fixtures and I can say it's more like MH spread used their wide angel lens.

Thanks for sharing. Those are some impressive numbers. You've been up and going with these for a while now. How is the growth? Have you seen much difference in switching out of the MH?

Thanks again.
 
Some night light shots.

The look is amazing, much better than the pictures. It's hard to shoot actinic/blue light.

Thanks kinlayan.

None of the led units have ever stopped working nor broke.
I don't know about replacing it but a friend of mine opened the fixture and said it's a simple soldering. You should contact the manufacturer for this kind of questions.
 
Hi bmco,

I am planning on replacing my 4 x 250 MHs over my 300 gallon SPS tank with LEDs. The tank measures 96" L x 24" W x 30" H. How many 156 fixtures would you recommend? Also, what are the dimensions of your tank (sorry if you already stated these)?

Thanks! Beautiful tank you have there!
