Thank you all for your help. You made me to understand the very basic of electronics.
So having 7 x 3.5 ft grow area (let say 25sqft) and running 4 of those lamps with HLG-240-C1750 drivers will give me approx. 40W/sqft ( 4 x 250.25= 1001W : 25 sqft = 40.04 ) More than happy with that :)
Case closed (unless somebody has better idea)

Here is the total cost of 1 lamp 250W:
(shipping to Canada included)
- led boards (2 pcs of 308 ) $ US 110.00 (Canadian kijiji site)
-HLG240H-C1750 driver $ US 65.00 (Onlinecomponents )
- heat sink (1/8" x 10" x 30")
aluminium sheet cut to size $ US 45.00 (metaldepot ) for the total of 220.00 US $
Add few bucks for cable,wires ,screws etc - it comes to less than 1.00 $/W

Seems you have your setup and ... for a reasonable price!
There is always a "better idea", but I would not worry about that.
Your 1000w QB are kicking ass, I can only say, you will not be disappointed!
