Artic blue would be of the Narva range & it'll never glow blue nor white for the candlesence output is too low,all these new 'blue' type globes are of 60/55wattage the only differnce would be the canlessence output from 3500 to 6000k. I personally recommend the Philips range as I used to sell these while working at Coventrys as I've personally seen the testing & comparisons between Hella,Philips,Narva,Raybrig etc & wet tests on all of them & Philips have come on top,I personally use Crystal vision H7s in my rolla they are a bit pricey ($80.00 twin pack) & also some emit excessive heat turning the headlights to turn yellow the crystal havent ..Oh & it emits a nice darkish blue tinge as well..
