This is indeed a tough one! The control panel
is skinny, more like that on a Sylvania set,
but the bezel on the "halolight" sets would have been white rather than color matched to the CRT. I found one Sylvania set in an ad that apparently does not have "halolight" ... but it has a planter in the base!

See the "Pierce" model... perhaps they produced a similar set without the planter?
Where was the set purchased? possibly it was a "regional" set that was not sold throughout the country?
