[Shop-talk] Fw: Re: Dimmable CFLs at Home Depot

[Doug Braun]

 I got this information from a DOE publication that
 benchmarked a lot of different LED, CF and incandescent
 light sources:
 
  
 http://apps1.eere.energy.gov/buildings/publications/pdfs/ssl/caliper_round_5_summary_final.pdf
 
 It does not seem to mention anything about ballasts,
 though.
 I suspect that a cheapo HD fluorescent fixture will be
 quite a bit less efficient than a high-quality,
 high-efficiency model.
