best quality xenon bulbs are typically manufactured by Osram in
Germany. Xenon bulbs require a ballast in order to ignite and sustain
light operation. A 35-watt xenon bulb will emit over 3000
lumens. Xenon bulbs can consume over 120-watts during the first 10
seconds of startup and require a heavy-gauge relay/wiring
Xenon Rebased Retrofit Kits:
inferior retrofit kits are typically manufactured overseas. Xenon arc-capsules are rebased into
typical halogen bases (ie: H1, H3, H4, 9005, 9006). These unscrupulous manufacturers
do not take into account that xenon bulbs create light differently than halogen bulbs. These kits are non-compliant, illegal and should not be sold or used.
item on the left is commonly known as a "casper shield."
Why it was given this name, we do not know. Items like this are a "patch-fix" solution for consumers
who have wasted money on an H4 retrofit kit. While this may help reduce
glare (and obviously reduces total light output), it does
not address the fact that xenon lamps produce light differently
than a halogen bulb. You are better off buying some quality high-output
halogen bulbs than wasting money and dealing with this junk.
