Eh 12-16 times means 120-160 ish in fixtures. Plus 36-48 bulbs at 14.5 watts a piece would equal 520-700 watts total.
Plus the price per bulb, 3-10 bucks a piece, you’d be looking at 4-5 hundred bucks easy.
Or do what we did, 4 of the ones linked above, 150 bucks and ten minutes of work and we had 40,000 lumens. And a total of 400 watts usage. In comparison, we replaced the old 4, 200 watt incandescent bulbs and maybe have 10,000 lumens combined using 800 watts.
More than one way to skin this cat, so shop around for sure.
