Do the bulbs that come with aftermarket hid kits, (reflector type), have the black band around them like the D2R's? Does it make a difference?

Chris: Here's an excerpt from a site I was referred to:
What is the difference between D2R and D2S?
The main difference is the U-shaped masking on the D2R that blocks out unpredictable light in certain directions. Also, the base has different notches. D2R was developed so that Mercedes could still use their reflector based headlights. They did not want use projectors like BMW. A glare box inside the headlight could have been used, but a mask painted on the bulb must have been cheaper to make. Using a D2R in anything else than a OEM HID headlight designed for the D2R bulb makes no sense. It will only reduce output. Some HID kits comes with D2R bulbs. Some amateur kit designers will even claim that D2R generally reduces glare in a retrofit. This is nonsense. The D2R bulb masking is around 3-4 a'clock and 8-9 o'clock when bulb is in right position. Those are not the (only) sectors that creates glare.
As an example, here is the data on Philips' 2 versions:
D2S: 3200lm, 4250K, 91lm/W, 35W
D2R: 2800lm, 4150K, 80lm/W, 35W
