The only problem with the 105W CFL's is that it's just closer to HID. I have 30W CFL's, and three of them give out the same number of Lumens for 15 less watts as the 105 tube CFL at stealthhydro. Plus, I can get better coverage since I can move mine. The best part of the 105's is just the fact that there is less hassle with making sure they are all wired.
In short, CFL's don't get more efficient as they get larger. |
