What I do is buy a sample or two of various brands/types and try them. I don’t buy the cheapest no name on sale “its too good to walk away from” bulbs. When I find one that works well I stick with it until there are clearly better options available (something new comes along). I’ve had good luck with TCP Instabright CFLs. Mine are essentially all in recessed “can” lights and are R40 style floodlights. The color is good (close to a incandescent), no visible 60/120 Hz motion flicker and on average last a long time in an enclosed fixture. The TCP (TCP is the brand) CFL’s above are 14 watts each replacing 60 watt incandescent bulbs for a average savings of 280 kWh over the life of each bulb. If your electricity costs 20 cents a kWh that’s a savings of $56 minus the difference in the cost of the two types of bulbs. The added cost of a CFL that does the job well is easily paid for due to the energy savings when compared to an incandescent.
For me CFL’s have nothing to do with “greeness” but simple economics. I’m trying to minimize my electric bill which is already way to high.
