So im in the process of building a sundew home and all thats left is my lighting. It's inner dimensions are 15.5 inches deep, 43 inches long, and 7 inches high. I have it lined with polished white vynil, ( like bathtub material) and covered with 1/8 inch clear plastic to keep in humidity. My main question is for lighting i have purchased a new workshop area lighting system. It holds six (6) 48" t-8 bulbs within the dimensions of 48" x 16.75". The bulbs that I purchased deliver the following specs from each bulb.
lumens- 2750
kelvin temp- 6500k
watts- 32 (t-8)
Color rendering indew- 82

So do you guys think this will be enough light for roughly 6 square feet and roughly how far away from the plants should I keep the lighting unit? The last question is will i have to harden the plants off to the increased light as if i was putting them out into sunshine for the first time?
16,500 lumens
a kelvin temp of 6500k
256 watts combined
a color rendering unit number of 82. ( from what I have read on the forum this only matters to the human eye, but still wanted to add here)

My thinking is this has to be better than the previous setup consisting of,
5900 lumens
the kelvin temps 36 inches of 6500 and 96 inches of 5000
110 watts combined
color rendering index- 92
Thanks guys
