LEDs or better fluorescent tubes?
I'm updating an office unit. I want to put daylights (5000k or 6500k) into this unit. Here are pictures of the ballasts and tubes currently installed. I am going to replace all the bulbs in the unit (about 44 tubes). What can I do with the lighting? Are LED tubes an option? Should (or can) I use T8's instead of T12? I'm looking for options.
