Fluorscent Light Intensities



Mark,
Thanks very much for your information.
I have been using Phillips tubes (mix and match) and this is their ratings for 
their normal household/commercial tubes

Bulb type Colour  Temp(K) CRI  Efficiency (lm/W)
----------------------------------------------------------------------------------------------------------------------------
Standard 54  6200  72  69
Super 80 84  4000  85  96
  85  5000  85  92
  86  6500  85  90

Beats the hell out of buying the specialized lamps.  Mind you, though, I have 
had better plant growth with the specialised lamps per se.
