Unfortunately no. The ballasts you have will only fire a 40w bulb. You can however upgrade the ballasts to run VHO
bulbs instead which would increase your output quite a bit. If your 150 is a 60x24x24, you can get an appropriate ballast to fire 2x140w VHO
which would make your tank much more diverse in what it can sustain. Inlcuding low light softies.
If your up on your electrical knowledge, a Fulham Workhorse 7 would work on these and would be cheaper than buying from an LFS
