Its possible your HID bulbs are nearing the end of their useful life. I've also seen in some cars the reflector bowl of the low beam projector begins to overheat and loose reflectivity.

Its possible your HID bulbs are nearing the end of their useful life. I've also seen in some cars the reflector bowl of the low beam projector begins to overheat and loose reflectivity.
That being said, the new projectors also feature "Hyperboloid" optics. A Hyperboloid has a secondary optic in the main lens and a secondary light source. This is generally use to provide supplemental output for the high beam. The projectors we tested have dual hyperboloid optics.
MFG Light tunnel test:
Low beam
Traditional high beam only.
Not pattern is wide and all, but no additional intensity from low beam.
Hyperboloid high beam only
Significant increase in central output from secondary optics. Spot pattern focuses lights light further down the road.
When hooked up, both traditional and hyperboloid will function as high beams giving you both additional spot intensity and additional height and width. .
One of the new projectors also has TIR supplemental optics.In A TIR (Total Internal Reflector) Each LED in a TIR unit centers at the end of a conical reflector. The reflector captures scattered light and focuses it forward. This projector has a TIR optic, traditional bowl chipset and dual hyperboloid optics. The TIR optic provides increase central output in BOTH low and high beam patterns.
The current Bi-LED projector we use has a traditional single chip-set using a half-reflector bowl and cutoff-shield to create the low to high beam patterns. Total down-road output does not change for high beam, but the pattern does expand to project light above the cutoff.
Testing details:
- Photos were taken with a Samsung S22 Ultra in auto mode to show pattern and hot-spot intensity.
- Car trailer is about 50 ft away to show beam width.
- Headlight was aimed with center on the side-exit door handle
- LUX readings were taken at the center hot-spot and on rear of trailer for off-axis output.
Results:
Current Bi-LED projector ("TALP")
TDC: 207 Lux
Off-Axis: 1.9 Lux
Notes: Strong central hot-spot and good overall width.
Projector 2: "2024 HB"
Dual-Hyperboloid
TDC: 185 Lux (10.6% decrease over current projector)
Off-Axis: 6.7 Lux (252.6% increase over current projector)
Notes: Slightly different projector bowl design significantly increases overall width and width intensity while reducing central output. This projector would be best used in luxury vehicles, but IMO isn't the best option for sport-cars.
Projector 3: "Copper Top"
TIR + Dual-Hyperboloid
TDC: 224 Lux (8.2% increase over current projector
Off-Axis: 2.5 Lux (31.5% increase over current projector)
Notes: Nice improvement in central output, Notable increase in pattern width and width intensity, but not as much as previous version. Note, the test version used a flat-cutoff shield instead of the stepped DOT pattern. The production version will have a stepped-DOT pattern.
I did test the high beam output on this model at over 400 lux.
Guess which one is the "coppertop"
I've decided to incorporate the Coppertop projector as an OPTION upgrade to our Lux King headlight system. I will announce pricing once those have arrived.
When I do drive in more remote areas at night, I find the C8's high beams to be pretty darn good. I ran some 100 watt halogen high beams combined with some long range driving (not fog) lights on a couple of European cars some years ago. The C8's lights don't reach as far as those pencil beams did, but then I don't drive 100 mph in the dark, either.
EDIT: Sorry, not sure how I ended up in the C6 forum.
I recently put a new set of LED headlights that have this same shape and style on my Lincoln Town Car. Vision is night and day compared to the old Halogen. These look similar in style so do the go right into the stock housing or are you making all new housing and so on?

Here's what it looks like with the current projectors. Aside from a crystal-clear lens, visually indistinguishable from OEM. The Copper-top projector's main lens will make this modification look a little more unique, but the performance will be light-years beyond the factory projector.
