  3. Nice charts. Not all that important to know about the improved efficiency over time for each different light, but still it clearly demonstrates the relative efficiencies today. It's amazing that incandescents are no more efficient today than they were 75 years ago.
     
  4. I was surprised to see that T5 tubes were more intense than a MH lamp.

     
  5. The graph shows them as more efficient, not more intense.
     
  6. I think I understand. Any info on light intensity versus lumens per watt that you know of?

     
  7. dont forget this one
