Philips ................ ...................................GE
The
Differences
The
closest non Asian lamp to the Philips design is the GE lamp
made in Hungary. I have highlighted a few things to look out
for when you are sold a claimed Philips product. Remember
a general accessory store or garage selling as a reseller
will probably not know anymore than you do. They dont make
it and they are perhaps also being deceived!!.
The
distance from the base is governed as this effects its optical
performance, not 100% though. See the line across the burner
envelopes. Here they are the same height. Above this point
will be down to product and production design. Notice how
much longer the UV chamber of the GE lamp is. Pay particular
attention to the top shoulder and how the lamp is finished.
Most discharge production lines make linear burners. This
is why the GE lamp at this point is un based. It will have
a welded point on the earth return lead at the top as this
is the common and well known production method the world over,
inc Asia. The PHILIPS lamps do not have any join in the earth
return lead. Note the upper shoulder shape and size. The Philips
line cost $125 million in total so it makes only one shape
and design , period. If it doesn't look like this it not Philips.
1.
A tapered top with a small rounded second shoulder. It is
finished with a final significant length of Quartz glass.
The Tungsten return wire is constant with no breaks and runs
non stop through the ceramic insulation all the way through
the base to the base earth ring on the D2. To rebase a D2
you cut the positive and the earth at these two points right
at the bottom of the base and slide the lamp off the base
moulding. These wires are then inserted into the new halogen
base and welded to the HT ballast wires. There is NO
reason to trim the glass or cut the
wire. Not only would it lower the quality but trimming the
glass makes no sense, is dangerous , time consuming and has
no advantages .Philips 1 product , 1 design, 1 production
line. FACT.
2.
This is a solid pinch that seals the inner burner. It is a
pinch to solid Molybdenum foil. Note the length of the foil
and where it start and stops in relationship to the GE product.
Cheaper product does not use the Moly foil.
3.
Note the overall construction , the shape of the burner, the
pinches and shaping. If the product you have varies in any
way from the above ask why.
ALL
OF THE ABOVE HAVE TO BE CONSIDERED ALONG WITH THE PRICE YOU
PAID. WITH ANY COPY IT MAY LOOK GOOD BUT IT WILL NOT WORK
THE SAME OR LAST AS LONG
HOW
MANY SITES SHOW YOU PHOTOS OF WHAT YOU ARE EXACTLY BUYING?
WHY
NOT ?
