You can't fill a bulb with air or hot tungsten wire will combust in presence of oxygen. You can't maintain vacuum either or external atmospheric pressure will break the glass. So, u have to fill it with non-reactive gas like nitrogen.
While nitrogen does react with hydrogen to form ammonia, the process is very difficult. It needs a VERY large amount of heat & a catalyst (usually Raney nickel) & yet, the yield is only 50%. You can look up Haber process in wiki or google for more details.
We can use inert gases like argon or helium instead of N, but they are more espensive & rarer than nitrogen.
hope it helps u
