The 105 watt looks same size as 65 watt bulb but with twice the size of the ballastAll in a 2x3 cramped together set up. I have alot more room but I am getting the most I can outa each bulb.
I have...
1 125w
And 2 105w and 4 23w
the 45 to 55 watt one(or whatever that 40 to 50 watt range is) is more efficent per watt then any of the large or smaller wattages. Keeping the small ones really close like 1-2 inches with fans will give you really busy plants with only a little topping its hard to see into these bushes interiors. At least thats from my experience.Yh your lights would be great man i dount you even need the small 23w blubs as they are only around 1300 lumens which for real wont be helping your plant much the big ones are .
i got the same ones
1 x 125w (12000)lumens
2 x 85w (5500)lumens
