Sorry Shiva for hijacking the thread. The light that I have is a simple cfl bulb that is 11w and 5000k. I want to grow a Den. spectabile under it. I was told by someone else that it would not be poweful enough to do much good so I have found another cfl bulb that is 60w and 6500k I am wondering whether or not to go for it. I have a basic lamp that is a clamp on fixture.

CFL works but you might consider small LED spots or chip spots. You can check them out on Orchids Limited web site. Chip spots are very bright and produce a very pleasant light. They also give very little heat.

Thanks Shiva. In regards to the heat I want some heat as I won't be putting on my heating over winter as I am saving my pennies http://www.discussworldissues.com/fo...lies/smile.gif So, any heat that I can scrounge from my CFLs would be greatly appreciated. I Have already bought the fixture so I don't want to buy another one just yet. I did look for LED that would fit it but they didn't go high enough in the lumens scale so I had to move over to CFL's. It is an ES CFL bulb that I have so hopefully it won't be too expensive to run.
