Those 114 Lm/Watts are if you run them at 350mA or 1Watts.
But if you drive them at max (4.5watts), it drop by half.
So it's either you drive them at max or buy more and run them at 350mA.
For his 120G tank, if we calculate that you need 3x250w MH normally (750W) and plan to use 500W of leds (leds are less efficient than MH, normally you would need more), if you drive them at 1W you need 500 leds at near 10$/each for R2 bin.
If you drive them at 4.5Watts, you need 100 leds but you drop at about 60lm/Watts.
Also, you need the puck driver that cost $$ each and you need at least 1 per 3 leds.
