  3. Thanks :)
  4. Hey man have you heard of Mega-rays they aren't designed for plants but their some of the best lights out there the closest you can get to actual sunlight here's a link:Mega-Ray® & ReptileUV Products
  5. They have a wide spectrum (really not needed here though, 2700 and 6500 will do) but have very low lumens. Lumens are key. Thanks for the suggestion though :)

  6. No, they are not.

    Lumens are a unit of measurement that accounts for how humans perceive light intensity, which involves a lot of green spectrum energy that coincidentally is "invisible" to plants (they are green, after all).

    There are other units of measurement that attempt to quantify light in a way that is more directly useful for comparison when the application is providing light to plants for photosynthesis.
