as far as i can gather different 'h' is a different size

e.g h4,h5,h6,h7

but i might be wrong.

I'm trying to up rate my candles, but the blubs I'm looking at come in h's 4,5,6,7

what will fit my 6n??

h4, pretty sure.

thanks mate, yer they are i just got impatient and took them out to check. think i broke one in the prosscess so ill have to get new ones now lol
