What's the pro and con of HID?!

I've searched around but found no answer.

What's the pro and con of HID?

What's the risk that you will take by installing after market HID kit?

Please don't tell me the HID is brigther and expensive... :)

 

[xerofighter]

pro - super bright lights
con - super expensive to buy. and when rosak how? buy again?

Thanks but I already said don't tell me the HID is brigther and expensive...

Pro:
1. Consume less energy
2. Brighter output
3. HID bulbs last longer 2500 hrs compared to normal Halogen which is 250 hrs

Con:
1. Expensive

Pros : brighter,can see furthur..reducing chance of accidents
lasts longer
way cooler than normal lights

cons : expensive
certain colour temperatures not street legal..might get questioned if stopped..
the bright lights piss other drivers off =D wait..this might be under 'pros'

resilienthunter, are you sure the HID produce less heat than normal bulbs? The reason I ask is I've seen many cars's headlights with plastic lens turn yellowing. My friend's headlights turn yellowing as well after a year of HID installation.

con : when it is too bright, its it quite irritating for other road users who don't use HIDs. some not properly tuned, 1 high 1 low. very very glaring and disturbing.

colour temperature means the colour of the HID..not heat-wise..

eg. 4350k is white-yellowish , 8000k is blueish..12k is purplish..

Oops I oversight your post coz I thought you were saying the HID is cooler as produce less heat. I do know the color difference but I wanted to know does HID produce more heat than the normal Halogen bulbs?

 

[resilienthunter]

i read an article that HID heat production is only ~60% of the original halogen..

dunno how true.. =)

you having difficulty deciding whether or not to install huh.. im goin to install next week =D

craps. i only read half your question. sorry. but basically, you will get the same answer as the one you already know.

 

[kher]

some say during raining time or like in genting higlands got fog u canot c well even ur HID is super bright coz it's also white after all...

 

[resilienthunter]

yep i believe visibility in the rain is compromised a little unless u take those kits which are slightly yellowish .. correct me if im wrong..

HID is hot?

the ballast only consume 35watts of power and normal halogen bulbs consume more.. some aftermarket 'white' bulb rated at almost 100watts which is required to use special harness. so, you do the math, it ain't hot as you think.

the best is 4350k to 5000k.. which is used as factory fitted HID for almost all car makers

it's a very good article regarding HID and everything you want to know is there

Dremel, thanks a lot for the link and lots of useful articles up there.

Yes, I do know the HID should produce less heat than the normal Halogen bulbs, but I've seen couple car's plastic headlights get yellowing after doing the HID conversion.

I'm not sure about automotive HID lamp. But in general lighting, metal-halide produces more heat than a halogen bulb.
Example:
small 50W halogen bulb (rocket - base GY6.35) bulb wall temp max. is 430C.
35W metal-halide (T type - base G12), OUTER bulb wall temp max. is 450C. the arc-tube temp will be way higher than 450C.
This is because of the high pressure arc-tube.

heat dissipation is not only related solely to power consumption. Types of lamp technology has to be consider as well.
e.g : ur house fluorescent tube 36W or 58W produces very little heat comparing to the metal-halide 35W.


So, in automotive HID, the 35W HID bulb could produces as much heat as the 55W bulb.

btw, HID produces a lot of UV radiation. Cheap bulb has no proper UV filteration. UV could also be a contributing factor to discoloring of the plastic headlamp cover.

just my 2cents
