DIY HID light kits ??
Kepp seeing these diy kits for sale on the net offering all required to convert your standard headlights to HID ones , seen a set today being offered at just £65 with a choice off colour temp outputs ie. white / intense white , blue / purple etc.
so okay whats the catch with these cheaper kits ?? only required for dipped beam so not a problem to keep to the original lights on full beam.
anything that will give me that intense blue / purple colour given off by the latest corsas / etc ?? why do some cars like the latest cors seem to give off an almost purple / blue effect when others just give a very strong intense white colour - is this again purely down to the power output off the sstmn itself ??
bit confused by it all ??!!
any advice would be much appreciatted.
cheers

Do a search on here for HID, also read the thread on the HID group buy. Some good info there, and links to sites that explain it all.
Basically, the prices are coming down, because other players besides Philips/Hella have entered the market. Whether the newer stuff is up to the original standard is open to speculation at the moment.
You DO need to be careful though. Optical alignment is the key to a decent light output. Just have a look at recent tests in Auto Express, when H4 bulbs with GOOD alignment scored better than supposedly higher wattage bulbs that were poorly made.
I mention this, since some HIDs are just an HID envelope glued to an H4 or whatever base, making the alignment hit or miss at best
Colour temeprature has nothing to do with power output. What it has to do with is Lumens, or light output.
Look at the graph of light output vs colour temperature on one of those sites above: You'll see that as colour temperature increases, light output DEcreases, with BEST LIGHT output at 4200K, and worst at 10-12000K. The 10-12000K look purple, the 4200K, bright bluish white.
Your colour temperature choice therefore depends on whether you want to SEE or be SEEN
