Does anyone ever question either the safety or quality of such
devices at a price approaching the unit price overhead cost
of stocking an empty box on the shelves and printing the coupons?

It would be like those old style flash bulbs in the "Edison A" base that
my father (former police photographer) used to screw into lamps and
light fixtures of the hapless victims of his office pranks.

My brother loaded up all the lights in his dormitory with those flashbulbs.
Got in a great amount of trouble for it, as I remember, when the Dean came
in and flipped on the lights.

If Walmart sells them you can be sure they have been tested by UL
or the equivalent and have been given a clean bill of health safety-wise.

These huge retailers have tremendous power over the manufacturers (or
importers)- if they product was complete crap and the customers came
back for refunds or replacements, the manufacturer would pay for it,
and Walmart would probably ship the entire remaining stock from all their
stores back to the supplier. So, chances are, they are "good enough".

An expensive electronic ballast globe type one (11W about US$20) quit
in one of our outdoor fixtures and I dissected it. Fairly marginal parts,
I think I could make good money at $8/unit factory door price, but not
at $2.50. I wonder if anyone has considered combining a CF lamp and
an incandescent, using the latter as a ballast. You'd get a blended
light and save the cost of all the fancy electronic stuff (I know,
bite my tongue).

Best regards,

If WALMART sells them, and they are electronic, you can be sure they won't
work after you walk them out the front door.

Walmart has a stated policy of buying the cheapest available device.  They
have NO quality control department.  Customer returns are not returned to
the vendor for analysis, just dumped, so the vendor never knows why things
are returned or what is failing.  The quality goes out before the name goes
on.

> combine CCFL and incandescent

This has been around for years. I can buy 160W lamps like this. No ballast
is required. The efficiency is lower than CCFL and the spectrum is wider.
They have to be mounted hanging down no more than 30 degrees from
vertical.

When a manufacturer tells you that a compact fluorescent has a 7 year
guarantee, they are banking the fact that most people do not track their
receipts for light bulbs, to be able to claim a free replacement.  It is all
based on actuarial science.  How many people even send in rebates for
products?  It is a marketing ploy.
