After having trouble finding shop lights (either too big or the smaller ones not enough light) I decided I'd go for those
energy saving lamps.
I bought myself 4 Philips Tornado screw-in bulbs (so I can use them later somewhere else in the house) and put those in place.
I went with the 20W bulbs, each having a 115W output(together 5000+ lumen) and after a few days my VFT traps started to get a nice dark red, same for the little hairy things on my drosera's and my sarracenia seedlings are sending up new pitchers.
Looks like they are having a good time now.
