Haven't tried those Tindo, so can't tell ya about light quality. In my 30gal tall I've been using 2 cfl's and they seem to be doing okay. However, a 30 gal tall is only 19 inches tall. You're talking not quite twice that distance so I don't know if cfl's will provide you with the necessary light intensity nor if that could be remedied by increasing the # of bulbs used.
Even cfl's produce a noticable amount of heat at least in the upper part of the tank. Then too, I don't have a glass layer separating the bulbs from the tank -- they shine directly into it no obstruction. I would guess that you will need look at having vents for heat to escape [keep in mind that means some of your humidity will too] if you have the lights shining unobstructed into the tanks. For my 90 gal, I do plan on sticking with the cfl's as they are inexpensive, but this time will have a glass layer separating them from the tank. Will be interesting to see how that works out.
