Has anyone tried one of these 300 watt cfl bulbs. I had a 150 watt cfl (before I dropped it) and it was really bright for 150 watts and it didn't require a ballast. The 300 watt cfl sells for about $70. Sounds like a no brainer. I was thinking it might be a good idea to have 2 or 3 of these 300w CFLs at ground level to really help flowering in the areas that do not traditionally get enough light from the hanging lights above. Oh, and I'm not talking about 300 watts equivalent. But actual 300 watts.
