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.
