Here are the bulbs I've tried:
LOW BEAM:
Right:
GTR Lighting Ultra Series 2 LED H11
Left (Top to Bottom):
GTR Lighting Ultra Series 2 LED (950 lux, 9150 lumens/kit, 5450 kelvin)
Diode Dynamics SL1 LED (577 lux, 2455 lumens/kit, 5200 kelvin)
Philips X-Treme Vision Halogen (334 lux, 1586 lumens, 3500 kelvin)
Osram OEM Halogen (284 lux, 1328 lumens, 3425 kelvin)
(the white cut-off line below the left light's coming from the misaligned left fog light)
HIGH BEAM/DRL: Philips Diamond Vision 9005
FOG LAMPS:
Diode Dynamics Luxeon LED, White (600 lumens, 5000 kelvin)
Diode Dynamics SS3 Pro LED, Amber (5200 lumens, 10900 candelas, 109 lux at 10 meters, 3000 kelvin)
As of now, HID is still a bit brighter than LED. HOWEVER, HID has already reached its technological prime & there's not been any new developments. LED, on the other hand, is still evolving & will later on outshine HID. HID's & LED's are compatible with PROJECTORS like our low beams as the projectors have already a set cut-off line to prevent glare. Hence, you can install the brightest bulb you can find & still be street legal (except if you use amber colour or some non-white colour which are usually not legal for street use).
Halogens that produce "white" light are usually tinted blue & are often dimmer than the yellowish 3500k. Primarily, these halogens are just for aesthetics. There are many tests on YouTube & other sites that show this. If you really want a white light that can really illuminate the road, you have to go either LED or HID. However, be careful as only high-quality LED's will create a proper usable beam & will last so much longer than the cheap Amazon ones.
Most of our high beams are reflectors. Though you can switch to HID/LED's, it's usually illegal for street use as they are have a different beam pattern as the reflectors were designed to throw the pattern emitted from halogens.
