Which is the brand you are now using for 90-100 & what's the cost please?
alternately you may try the Extreme Power from Philips is is 60/55 but gives ~90% more light at the expense of life.
as per RTO regulations we are not supposed to use 100/90 W.
moreover after one or two years your lights lens will look yellow due to the extreme heat produced by halogen 100w
You can go in for Philips extreme 90/100 or you can also try out osram night breakers 55/60.Both provide good job with the lights thrown.
