I agree. The fluorescents waste power in several ways: light spilled into aisles due to difficulty focusing them, inefficiency if they run too cold (which is extremely difficult to control with any certainty), increases in refrigeration requirements, and needing to be left on for long periods of time to achieve acceptable lifespans. In addition, modern high-power LEDs are beginning to overtake even the most efficient fluorescents in terms of brute efficiency. At work we have an ice cream display freezer using a 7 foot T12 high output tube that probably does about 30 lumens per watt useful light into the case. :thumbsdow I was going to replace it with reflectored T5 fluorescents; after reading this thread, I'm now contemplating hooking up a bunch of CREEs, SSCs or Rebels! :thumbsup:
