We see through a bulb darkly: update

Yet another two letters about the letters about the light-bulb editorial. Both of these take the view of a contrary commenter, whose views on light bulbs and nearly everything else are sharply at odds with mine; here are excerpts.

Says Ed L. in St. Paul, Minn.:

...incandescent bulbs are replaceable now, by fluorescent and other lighting. [For example:] Light Emitting Diodes (LEDs)...

When an incandescent flashlight bulb expires, it can be replaced with an LED lamp which will last much longer. Or, throw the flashlight away, as suggested, and replace with a cranking charger and eliminate the need for a battery.

Power-on and indicator lights on many electrical appliances are regularly configured with LED lamps. Look at most computers, and the flashing lights, which dim.

As for Christmas tree lights, LEDs offer an impressive return on investment...Safety is also significantly enhanced...An outside holiday decoration which I light, that used to run with incandescent bulbs at 550 watts, now runs with LEDs at 6 watts.

Bicycle headlamps and taillights are almost universally converted to LED lamps...flashing red taillights many cyclists use have been mostly LEDs for several years. Check out any bicycle store...

Roadway warning signs and signals are increasingly switching to LEDs, for lighting enhancement, incredibly lower operating costs, and longer life. And remote roadside emergency signage, running from solar panels, clearly excels for safety...

The shift to LEDs is indeed illuminating.

Says Dave G. of Oxford, Conn.:

...As to the mercury issue, I have to agree that this is a very real problem that can only be solved the same way that soda cans no longer cause quite the infestation that they once did -- deposits and redemption areas. IKEA has already taken the lead in recycling CFLs, but IKEA stores are not everywhere, so more recyclers are needed. Let's step into the 21st century with a little less dread.

Um, we're already in the 21st century. But that's a minor detail.

Update: Here is a link contrary to the contrary (hat tip Crusader Rabbit). And one from MK.
