Any suggestion of my tank?

I just got a new LED aquarium light last week.
Here is the size of the tank,both SPS and LPS:
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, PAR reading:265mmol; coverage:1.28 ㎡.
40 inch: 18,900 lux, PAR reading:206mmol; coverage: 1.76 ㎡.
60 inch: 14,400 lux, PAR reading: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.

Are you able to change the led lense? You might just need to raise a little higher but using a lower degree lense. Par value at around 300ish at the bottom is considered well lit.

No, this LED lighting is not dimming one, as the optical lens is built with a firm degree, it is hard to change. Now i might have to hang it higher a bit and wait for my new light comes.
