Haha I figured out what percentage their other products are reduced by also, I did round my answer though.1) $116.28
2) Sale price percentage of the regular price based on website for NooPsyche K7 V3 Saltwater Reef LED Light For USA equals 66.44295% ( $198.00 SALE Price, Regular price $298.00).
Noopsyche K7 V3 75w LED w/Mount Regular price is $175.00 X .6644295% = $116.27516
But now comes in the complete unknown. Is the controller a separate physical unit or is it going to be a phone app? So a lot of guess work here. The NP/Noopsyche K7 V3 Central Controller can be seen on sale at $39.00. I'll cut that in half to $20.00 for the smaller light. But if it's a phone app it should cost $0.00. So I'll split the cost again for guessing purposes to $10.00. So $116.28 + $10.00 = $126.28. (And yes, I put entirely too much thought into this as I drank my morning coffee, especially since it's still just a random draw chance of winning.)
Also, I spent an embarrassingly long time trying to find the price of their now discontinued X4 light, which is the exact same form factor
