I know where I can get a tube for a Thorn 2D high efficiency fluroescent....
but does anyone know where I can get the whole thing with ballast/electronic
or otherwise. I am particularly looking for a 16W since I have an uplighter
that it fits perfectly in.
[copied to sci.engr.lighting for any further comments]
It's really difficult finding electronic ballasts designed
for the 2D lamps. I have used the Philips Matchbox Blue 124
electronic ballast with the 21W 2D lamp (which is same
physical size as the 16W 2D lamp) and designed to drive
similar rated tubes, and it seems to work perfectly.
Also, the Philips Matchbox Blue 109 ballast works well with
10W 2D lamps, although it's not claimed supported either.
The Philips Matchbox Blue ballasts are tiny instant start
electronic ballasts. They also do a Red range which are
preheat (or programmed start to Americans). They are
available in rectangular cases, and long thin cases (and
bare boards in theory, but I've never seen anyone stock
RS Components do the lamps, ballasts (Blue range only),
and lampholders. Lamps are available in 2700K (home use
to match filament and retrofit compact fluorescents) and
3500K (typical office lighting).
BTW, Thorn Lighting sold their lamp business to GE years
ago, so you will find the 2D lamps are now sold under the
GE Mazda name.
