Without getting in the politics of energy savings, and whether one type of light bulb is "better" than another, or whether the greatest environmental cost of a type of bulb is in the production, use, or disposal phase of its lifecycle, or whether one really lasts longer than another, I thought I'd share with the rabble a little evaluation I did on three versions of the same GE "energy smart" brand Compact Florescent Lightbulb (CFL).

Last night at the grocery store, while angry mothers were close to rioting over the milk situation (there was not a container remaining), I was distressed to see that my favorite halogen bulbs have been discontinued. A light in my living room has gone out, and I need a replacement bulb. One of my long-time objections to the new CFLs is that they produce a garish light, capable of transforming the loveliest living room into an industrial workshop at the flip of a switch.

I noticed that the 60-watt bulb equivalents came in four flavors: bright white, cool white, soft white, and "sunshine." Unsure of what each of them meant, I decided to buy three of them (discounting the "bright" one on its name alone) to see for myself how they look at home. For comparison's sake, I also bought two GE tungsten filament 3-way bulbs (30-70-100)--one in the "Reveal" line and the other a "soft white," not otherwise marked. I realize that a 100 watt bulb is not a fair comparison to a 60-watt-rated CFL, but it was the bulb I would want for the three-way lamp that needs the replacement, my plan B in case none of the CFLs suited me.

I compared them side-by-side, two at a time, in lamps with ivory shades, selecting the one I liked the best in each round beginning with the CFLs:

Sunshine: Least favorite - casts garish blueish light.
Cool White: 2nd favorite - casts a crisp, white light, but lacks soul.
Soft White: Favorite CFL - casts a warm, yellowy-white light that is nearly indistinguishable from that from a tungsten filament bulb, but almost too yellow, like it's trying too hard.

At this point, I took the loser out and popped back in the 60-watt halogen bulb that was in it to begin with. They were similar, but the halogen gave off a slightly brighter, slightly whiter light.

Now I tried the 3-ways against the Soft White CFL.

The "Reveal" cast a crisp white light, with soul.
The generic one cast a dreary light that reminded me why I stopped buying those kind a long time ago.

So, which bulb will replace the burnt out one? The winner is the "Reveal" three-way, because among the new bulbs I had it was the one with the light I liked the best, and being a three-way, I can make the lamp dim or bright as needed. My preference is still with the halogen bulbs, but if I ever had to, I now know that I can live with the "soft white" CFLs.

Rex, clearly with too much time on his hands.
