Ok, so the eyes don't lie. The high beam in my TLs were brighter than the JW. Either way you can't loose. Both are dramatically better than stock halogen.
Don't thump your chest too hard. Here are some numbers from a "fancy little meter":
All readings at 25 feet in front of the vehicle. Vehicle lights are wired/relayed straight to the battery and engine is running.
Baseline. A pair of 1980's vintage Cibie Z-Beam headlamps with Osram bulbs threw 583 LUX lowbeam and 970 LUX highbeam
A pair of IPFs with their bulbs like the $126,000 JK Brute wears threw
517 LUX lowbeam and
513 LUX highbeam. Yes; highbeam was lower.
Hella ECE with Delta's best bulb threw 339 LUX on low and 653 LUX on high.
Hella ECE with Philips Xtreme Power bulbs threw 695 LUX on low and 1619 LUX on high.
JW Speaker 8700 (not the Evolution, the original) threw 630 LUX on low and 1139 LUX on high.
Trucklite Phase 7 (prototype, not a production unit) threw 416 LUX on low and 1870 on high. The production units
never did as well. EDIT -- in fact, both of the prototypes stopped functioning in a few weeks and Trucklite replaced them with production models. They took the prototypes back to the lab for forensic deconstruction.
So, overall, if you just want light down the pipe, get some very-affordable Hella ECE reflectors, Philip bulbs, and use a harness and relays.
Or get the Rallylights 90mm H9 kit --- which blew that away.
Or get the Rallylights 90mm HID kit --- which blew away the H9.
Best of the best at a reasonable cost?
Scot (from SC) put HIRs into both his high and lowbeams. I had to change the scale on my meter to measure his highbeams (I did with the HID too).
