Replaced low beam globes about 6 months with Narva HB4 Plus 30s. Very happy with their performance but they have both blown recently. I there an issue with longevity with these globes?

Good point Graham !

I used to run 4 Phillips 90/110 globes iin my Commorore, had to change every year, to keep up efficiency.

Switched to Navara D22, 3.0lt TD, with poly carbonate everything and had to run 55/60 globes,, I very soon switched to Phillips +50 Blue Vision, and been in for 3 years now, and do not look like blowing...
Mind you I have to squint a little on low beam, but that is the design of the light itself,,,,I swear that the little "nip" who designed those headlights, never drove a vehicle at night, otherwise he would have done a lot better job.

Higher output globes create more heat, more heat equals shorter life.
As a first step remove any headlight protectors that stop fresh cool air from hitting the lens, try not to use headlights in daylight hours when it is hotter and if you continue to blow globes go back to the originals or better still fit HID's.

I gave up on higher powered globes (90, 130 etc) due to short life, but when I was using Philips +50s they lasted for years.

The +xx globes do not draw any more power so they can't produce any more heat.

True high power globes like 55/100w, 80/100w and 90/130w and a few other combinations use the filiment with differant gases to increase light output and when you go higher in wattage the winding of the filliment becomes thinner, with high powered globe filiments seeing they have smaller windings they have a common trait of the filiments vibrating and in the end the filiment breaks and this is why you will get a shorter life the higher you go in wattage.

With + 30, 50 and 80's the filiment is the same (winding size) as the standard globes ( this is why the have the same power consumption as standard globes but higher light output) but they use a mixture of differant gasses and reflective coatings to increase the light output...the higher the output the higher the temp.

You can buy heavy duty lights globes that have a suporting bridge in the middle of the filiment to stop filiments vibrating and breaking but they are only avaliable in 12 and 24 volt standard output globes and mostly used in trucks.

One thing halogen globes don't like is having the wrong voltage sent to them, the best voltage is 13 to 13.2 volts, any lower and the globe will form deposits on the filiment as the gases inside the globe will not vapouris correctly and any higher voltage the filiment will over heat.

Check you headlight voltage, we have not had a +30 or 50 come back not working yet.

Most standard globes have a life of between 800 and 1000 hours.

Thanks for your detailed reply Richard. Will check voltages but glass and filaments look pristine naked eye, just the filament has broken away from the lower contact. If voltages check out OK, I think I will give these globes another go as I have been happy with their performance as far as illumination is concerned.

Thanks to others for their input too.

Regards Mark

What's the old saying about doing the same thing and expecting a different result??

Look for the Philips globe that equals the Narva spec, and it will do what the Narva didn't - last.

Mark we don't sell the Narva brand due to quality.

We only recondmend Phillips.

OK...OK...sounding a bit like SWMBO. I'm a slow learner but I finally got the message! Got a pair of Phillips. Put them in. Work great in the daylight. I am sure they will work great in the dark (like me). Will let you know in a couple of years.

Thanks again fellas!

Best wishes, Mark

Thats OK Mark, nothing wrong with Narva just that they are lower quality then the Phillips.

It the same thing as anything else you pay for what you get.

Check out the Phillips new +80's
