My little saltwater tank with LED light

[davemedinis]

My saltwater tank size:
25x15x20 in inch.
The new LED aquarium light arrived yesterday.
Built with 72pcs 3W LEDs, input voltage 3.8,input current 700 mA.
Actual power 192W.
Based on White 14000K:460nm=2:1, I measured its lumens and PAR value, it was:

2 inch:113,300 lux. PAR value:1760 m-2s-1.
12 inch:112,300 lux,1280mmol;coverage:0.8 ㎡.
20 inch:78,000 lux, 728mmoll;coverage:1.12 ㎡.

And since my tank is only 20inch in depth, we measured the other data in my friends' tank.

30 inch :46,000 lux, 265mmol; coverage:1.28 ㎡.
40 inch: 18,900 lux,206mmol; coverage: 1.76 ㎡.
60 inch: 14,400 lux,138mmol; coverage: 2.269 ㎡.

But now it seems this 192W powerful LED aquarium light is too strong for my little tank, I am going to get another lower power LED, probably 24pcs blue 460nm and 24pcs White 14000K,total power 130W is enough.
I am trying to post a picture here, but it doesn't work.

Wow. Looks amazing, I love it.

Thanks,Kyle, but it seems my little tank doesn't need such a giant LED lighting.

Probably not. More isnt always better. I think the 130w should do you good, but itll be bluer with a 1:1 14,000/Actinic ratio. I actually prefer bluer light so Ill be looking forward to an update. :)

Agree, and I just got the parameter with the 130W,1:1 ratio, I think it is pretty good for my tank.
2 inch: 61,700 lux;1278 mmol; coverage 0.5 ㎡
12 inch:60,800 lux,1250mmol;coverage:0.785㎡.
20 inch:32,400 lux, 602mmoll;coverage:1.06 ㎡.
30 inch:18,800 lux, 258mmol; coverage:1.76 ㎡.
40 inch:12,600 lux, 188mmol; coverage: 2.13 ㎡.
60 inch: 5,670 lux, 118mmol; coverage: 3.46㎡.

Sounds good. I bet you can keep some pretty awesome stuff in there. Do you have pictures with it on? Or is that just specs off the web?

Wow,really? What a coincidence, would you mind sharing something about your aquariums?

10 gallon, about 12 lbs of rock, 2 inches of sand. I have 3 Astreas, 2 Nassarius, 2 Scarlet leg hermits, 3 Blue legs and a tank-bred Ocellaris. Just running 2 HOBs with rubble rock now, but Im gonna get a Koralia 240 for horizontal flow and a 4 bulb T5HO light on the way. All softies and a few LPS corals right now.

That's fine,you like T5,if i were you, i might get two pcs 9W or 18W LED bars.

 

[kbuser92]

I tried and neither was bright enough for me.

Oh, sorry to hear that. Did you try the LED moonlight or high power 1W or 3W LED light please?

 

[kbuser92]

No. Oh well. I know Ill probably be using AI Sols or Radions when i do my next tank.

Ah.yes, they will be great~

My new 140W LED aquarium light arrived last week, and data was measured at my friend's store, i have been very busy since last week and have no time to set it up. Will set it soon.
PAR was higher than i expected before. More than 270 mmol at 80cm.
