Been looking for replacement H3 120w bulbs for my piaa drive lamps on my 00my, can only find 100w or 130w locally and the dealership wants £24 per bulb for 120w piaa's own replacement bulbs. Any ideas anyone.

I used 130 watt bulbs from Halford in mine no probs!!

I've got 130Ws in my PIAA driving lamps. No probs either

I use 130w ordered from GGR. Delivered in a few days. Much better than 120w. Suggest you upgrade your head and side light bulbs at the same time to PIAA. If you don't change the side lights they will look yellow against the head lights. Details are on their web site as Sonic says.

Hi

I've had 4 genuine PIAA bulbs fail,normally after about 6 months use.Replacements were 16 pounds from the dealer or 18 pounds from Demon Tweeks!!.

I'm also trying some of the 130 watt Halfords bulbs (5 pounds each) to see if last any longer.

Hi All,

As we are on the subject of bulbs. I've currantly got standard main and side light bulbs + 100w in my PIAA's. I want to upgrade all of them.

Is there anywhere I can get the hole set together. A PIAA package deal?????.

If so where can I get them ?

Thanks Andy

Will do.

Had some PIAA 150/150W bulbs fitted yesterday to my std headlamps, they draw 85 w so the std wiring is fine. The differance is amazing over the std bulbs.

Thanks Roger Clark Motorsport! my drive home was fun.

If you've got plastic reflectors (MY99 on), let us know how long before they develop large ventilation holes in the back.....

Walker,

What you written doesn't make sense. 150W bulbs require 150W of power, not 85W. Either they are 85W bulbs or 150W, but not both. Those manufacturers that claim 55W bulbs give out the equivalent light to an 80W bulb are talking crap.

So tell us, what have you actually bought and for how much? I can imagine that a 85W/85W front bulb will give out a lot more light than the standard 55W/55W but it does draw higher current and will increase the operating temperature in the light.

RJC,

Yes an 85w bulb will draw 85w, but it is possible for different bulb types to convert power into light with a greater degree of efficiency e.g. more light / less head.

Compare a 60W incandescent bulb to a similarly rated florescent bulb for example.

Cheers,

Alex

Yes, you are right but you are also talking about two different technologies. I'm assuming that we are still talking about tungsten filament bulbs and the efficiency of these things is pretty much fixed.

Take a sample of all the 55W bulbs out there and they will all have pretty much the same brightness. You don't get something for nothing. As most of the on-line guides show, about all you can do if add a lens to change the distribution of the 55W of light generated so that you have 'hot spots' in different places, usually resulting in loss of peripheral vision.

The only way to get more light out and still use 55W of power is to use another technology like HID.

Guys

The bulbs are new in, they are PIAA H.I.D. Platinum 150/150w but only draw 80w.

They cost me £67-86 +vat and £8-69 for the side lights from Roger Clark Motorsport(01455 828610) fitted.

I`m sure they will be fine, if not i`ll be going back, they are decent lads and i know they would sort it!

"Phillips" new vision range just stormed a H4 test in "revs" magazine ( Dont buy it I just skip through whilst in tesco's!!!

£20.50 delivered for a pair

Rjc,
Bulb manufacturers now have better QC, getting a greater amount of Halogen or Xenon inside the bulb, these gases help the filament work, and also give out a small amount of secondary emissions, meaning that what you get is a bulb giving out the equivanlent of 120W ie but only drawing 55Wie.
Youre right. On the energy stuff, Newtons third law, whats going on is a piece of marketing by the bulb manufacter's
