OOOO H.I.D Lamps

LOL.. I have used 100 watters before on my car they do give of more light, but burn out real quick.. I believe the highest wattage allowed on the road is a 55 watt bulb.. Now the hid maybe say a 35 watt bulb but will give off more lumens of light per watt of power.. So while like 5 times brighter they would be legal on the road... hid rules :cool:
 
you can over volt halogen bulbs safely by about 12% and they do give a lot more light.
genuine 100w bulbs would be a dull glowworm with 55w electrics, or they would burn out your wires, not sure which, I'm not a leccy expert.
the ring xenon bulbs have a higher %'age of zenon in the inert gas within the bulbs, so they are allowed to burn hotter, therefore whiter, or they use a more delicate element that needs the extra zenon to prevent them burning out.

real hid's like dave's are nothing like normal bulbs and £135 is absoutly bargainous (usually a £1000-1200 option on new cars) and about £500 PER LIGHT as an aftermarket box of stuff to fit to your car. real hid's have a halogen 'equivlent' of a 100w halogen bulb, yet they are actually still 50 or 55w.
I know with bikelights that a 10w HID set, burns 13w of power, yet is the 'halogen equivilent' of 35w.

but don't they have a limited number of switchons? i.e the life of them is measured in turn ons, turn offs, rather than hours?
 
so does this SA fella have loads to sell, or just the one?

just mk1 dipped beams are poo, and using front fogs isn't a legal option.
with mk1's though the main and dipped beam are as one (H3 or H4?) so how would that work, does anyone know?
 
The HID lights which are fitted to cars as an option or as an aftermarket accessory are gas discharge bulbs, they have no filament and work on electrode eaxch end of the bulb envelope. In order to start the discharge you need a ballast which can provide a high voltage, hence the reason you need more than the bulb in a kit. The colour of the light and it's intensity etc is governed by the gas mix in the bulb and not by the electrode material or any filament. They will normally last for the life of the car in normal circumstances and require less power to operate than a standard bulb. More of the energy is converted to light and so they are also cooler.

Impurities in the gas envelope are what causes a bulb to "wear" out, in the case of the filament type bulb it causes oxidisation of the filament and in the gas discharge it is a combination of impurities which are released preventing the discharge (in many case water vapour left during manufacture etc).

The perfect bulb could be produced but it increases manufacturing costs to a point where it is not viable compared to bulb replacement.

I spent a whole year working on the design of these bulbs at Philips in Holland. There is also no reason for them to blind people if properly adjusted, on the factory fitted units they must have a auto levelling system but it is not required for aftermarket fitments.
 
Even so, HID 'bulbs' fitted to standard lamps are illegal here in NZ. The entire lamp has to be replaced for an approved item (not just the bulb). Something about the HID having a different-shaped point source of light. Most halogen bulbs have a longitudinal filament (H4), some like the H3 have a transverse filament. Reflectors are designed around this short spread of light generated.

The HID bulb has a different shape, so the reflector produces different light; Dave, what do you have to say about this? Is your beam pattern still cut-off? Are there holes in the beam?

I always thought the Mk2 Punto had fantastic headlights, even having that nice coloured twinkly effect usually associated with gas-discharge lights (but in this case produced by poor-quality optics :rolleyes:)

I agree with jug (or at least, I know what jug is saying) about the coated bulbs to give a 'whiter' or 'bluer' light - they do this by filtering out the yellow-coloured light, so you end up with less illumination, particularly of such things as yellow or green roadsigns (in England, you might not have these). In short, coloured bulbs are a con. And wattage ratings aren't reliable on no-name bulbs. Really cheap bulbs may even have the filament in the wrong place, which is bad for the reasons described above.

Does Sharon know you have bought them with the weekly shopping money if she finds out you will get a clip round the ear :nerner: :tempt:
 
I thought the xenon +50's on my 1.6 were good but they aint a patch on the HiD units fitted to the JTD! Was initially disappointed that the JTD has no front fogs, but have found since that it don't really need them as the headlamps work just as well in fog, mist & heavy rain...
 
Hi!

For the guys who have fitted HID lights on their Punto MK2s, does the D2S bulb go into the bulb area completely or does it jut out a bit from the back?

Mine doesn't seem to go in completely, and I can SEE the light from the engine compartment!

Any advice?

THanks!
