24" T5 4 bulb vs. 2 85w CFL.
I am in the process of building my first orchidarium to help with humidity issues for my mini orchids. I am converting a 20 gallon tank that is 30" long. My questions is, should I get a 2ft 4 bulb T5 fixture or just use 2 85w CFLs? I get 96w with the T5s and 170W with the 2 CFLs full spectrum. Do more watts translate into brighter lights? I read a post about someone using a 200w CFL and low light levels as compared to the same wattage using T5s. Want to grow some higher light orchids so I was hoping some of you might have some ideas of light levels comparing the two. Thanks for any help I can get.
