Not me. Go do some googling on the subject. Try "slr second tier" to start.

If it were my opinion, I would prefix it with IMVAIO or IMHO.

You could get one of the new MagLites that use high power LEDs.
They are *very* bright, have a natural (not very blue) color and can
even focus. They're available in 2, 3 and 4 cell versions for C and
D cells. There are also MagLite LED kits to convert older MagLites.
Unless the lights are used very frequently, it still makes more
sense to keep using alkalines batteries since they last so long. A
2 AA cell LED version was recently added to MagLite's line.

Well the solution is obvious--buy more expensive flashlights.
I prefer C cell flashlights, but unfortunately the selection is more
limited than D cell models. With the Maglight 3W Luxeon LED flashlights
you can buy AA or D cell models, but for the C cell models you have to
buy a regular non-LED model then buy the retrofit kit. You really want
to use rechargeables with these flashlights as they draw a lot of
current, 3 watts at 2.4 volts is 1.25A. The eneloops would be ideal as
often flashlights are not used for long periods of time, but when you
need it to work it has to work.
The Maglite has a big advantage over most other LED flashlights because
the spot to flood beam adjustment still works with the LED conversion.
Very few 3W LED flashlights have this capability.

It seems to me that C and D cell adapters would be a good application
only on those devices that shut off, as you said, and on the LED upgrade
add-ons for some flashlights you can now buy. Replacing an incandescent
bulb with LED, and D cells with AA cells would be feasible.

Well maybe for kid's toys it's a legitimate concern to worry about
polarity reversal caused by unintentionally leaving a toy on, but for
adults that are more responsible about turning things off when done it's
not a big issue. I do mention about the cell reversal issue on the web
site, and warn about not draining cells all the way down.
