I assume the HID 6k may be brighter than the 60/55w Piaa? has anyone had both of these bulbs to find the answer? i wanted to install an adjure tri star black dot and was wondering if the HID would fit. i know where to buy both bulbs from but where is everyone buying the adjure tri star from? any help, thanks
Bigdog performed a test on H4 headlight bulbs. Testing Lumen output consistency in heat and overall bulb output and life.
They found that for a good upgrade from your stock bulb a
Sylvania Silverstar 55/60w H4 style performed very well and was at a very consistent lower temp than all the others tested. The temp did not go much above 160 deg, the others tested had temps go from 180 all the way up to 200+, this makes for a short bulb life and can even cause socket failure.
Not sure if that helps you or not but you might find it to be useful somehow.
Oh yeah, and a Silverstar is around $20 each retail. Not bad, I use them in everything I own and they work awesome.
