the u.s. silverstars are 60/70 watt. euro + 50% osram silverstars 55/60.
it was probably just a typo in the above post. the piaa are probably 55/60.
my personal biggest gripe with piaa is they are way too expensive and only maybe last around a year and also i feel their advertising is very misleading.
example there is no-way i 55/60 bulb can illuminate 120/90 watt [just an example].
do a search here on piaa bulbs. kedcj6 [something close] neil had a very good thread on this some time back.
