I think the technical reasons are similar to need for fl compatible (fl)
ballasts and dimmers.

What's the deal with not using compact fluorescent lights (CFL) and with
'control devices'?

I see this on the packaging at Wal-Mart and online at
http://www.bulbs.com/

The only thing that I can think of which would be bad to use with CFLs
would
be dimmers or the photocell operated controls which make normal light
bulbs
flicker as they decide to 'turn on' in the evening. I've got some
photocell
controllers (screw into bulb socket) on the exterior of my house that have
multiple sensors and work some magic so that they just 'turn on' (no
flicker). I'd think that these would be OK for CFLs but there's still that
warning there.

the result *may* just be unreliable switching.

you should get intelligent answers asking on a electronics newsgroup (serach
google with approp. words to find best group)


Any thoughts or ideas on this?

Thanks,

Brad
