I'm upgrading my lighting for my 55g FW planted from 2x18" 15W Tropic Sun 5500K bulbs to a fixture I bought at the hardware store that takes 2x32W T8 or 2x32, 36, or 40W T12s. I opted for the 40W T12s.
Here's the dilemma
I got 2 Verilux Instant Sun 40WT12s at Menards for like $12.50 each. They are:
6280K
lumens not listed
26,000 hrs
color rendering index (cri) 94.5
I then found a 2 pack of GE Daylight 40WT12s at Wal-Mart for $9.50. They are:
6500K
3050 lumens
20,000 hrs
cri 75
If someoner could please decipher this code for me and tell me which is better, or if there is another bulb I should be getting, I would appreciate it!
