I rate this OPT-7 Fluxbeam LED headlight bulb as a 10 because 5 is just not high enough. I bought this bulb because it had the highest lumen (3500) rating I could find with 6000K (white) color. It’s a bonus that it only draws 40W of power. The OEM bulb draws 55W. Shipping was very fast thanks to Amazon Prime. Installation only took about 20 minutes and half of that was to adjust the bend in the locking wire a little to clear the fan on the rear of the bulb. Be sure to read the instructions. It all fit inside the headlight housing of my 2015 Honda Shadow Phantom which has one of the smallest headlight buckets there is. This bulb is BLINDINGLY BRIGHT!!! I made the mistake of looking directly into the headlight. It took several MINUTES before I stopped seeing stars. Can't wait to try this out at night. If you want a BRIGHT white headlight, THIS IS THE BULB TO GET. Part number for 2015 Phantom is: MT-HW-HL-6.
