I had 8k bulbs and aftermarket housings ( no high beam) Then swithched to the 4 runner front clip... Repalced bulbs to another set of 8k's in the composite lamps... For anyone who says the light output is sacrificed above 5k is nuts. Anyone in SoCal can go for a ride in my truck at night and see the output is WAAAAAYYYYYY better than the factory sealed beams. Closest to white is most light output, but mine are very blue and outlight any factory ones on the road. I,ll post a vid if need be. Once you get above 8k, the color seems to take over (unless you are running projectors). Just my .02.

 

This may help some folks trying to decide what kit they want
The differences in color produced by HID bulbs come from the ignition of the xenon gas inside the bulb. The color temperature of the HID bulb which is measured in Degrees Kelvin determines the color at which the light will burn. In HID kits this usually ranges from 4300K to 12000K.Light output

Many believe think that the higher the color temperature, the brighter the light output. Contrary to this common misconception, the lower the Degrees Kelvin the greater the light emitted. Therefore, if improving your driving visibility is your primary reason for purchasing and installing a HID kit, it is best to choose HID headlights with 4300K. Above this, light output decreases slightly, for example, a 8000K bulb will have ten per cent less brightness than a 6000K bulb. While a 4500K bulb will produce three times the light of a traditional halogen one, 10000K HID bulbs will only produce twice the light of halogen bulbs.
Color range

Halogen headlamps have a color temperature or around 3200K which produces their yellow appearance. A HID bulb with 4500K gives optimal visibility and produces a fairly white light with a slightly yellow hue. This light is the closest to daytime sunlight and therefore the most natural kind which is easiest on the eyes. 6000K is one of the most popular colors as it is the purest of white light with a slight hint of blue, combining the two appealing features of HID kits: greater light output and a distinctive HID headlight color. The next common temperature color after this is 8000K which has a stronger blue hint. 10000K - 12000K produces a deep blue to violet light respectively.

I've got a cheap 35 watt 6k and I can see pretty good .in the rain it's kinda sketchy tho

yup. i heard that the higher wattage balasts will "wash out" the color hue of the bulb (from reading on DDM website). so a 6000k with 55wat will = a 5000k color/output......? generally making light color slightly brighter?

 

For the last 6 years + i have run the DDM 55w W/ 8k bulbs in 6 of my cars/trucks and installed this same set up in atleast 10+ friends and familys cars

I belive the 8k bulbs with the wash out from the 55w ballist give a super clean bright white with out the blue tint

 

I hope somebody will be able to help me with my issue that im having. I bought some cheapy ebay HID's and housings from here 7x6 H6054 Clear Square Projector Headlight Head Light H4 6000K HID Thin Ballast | eBay and im fairly happy with it. Well im sorta happy since Im not even able to run the HID's in them yet because I cant figure out why all they do is flicker the moment plug them in and turn them on. Ive looked around and saw that it may be a bad ballast, contacted the seller and they sent me new ballasts, still no luck though. The new ones still flicker. I was looking at possibly buying one of these HID Canceler Capacitors 2 Pcs HID Flicker Error Warning Canceller Canbus Capacitors Computer Decoder | eBay Just to see if that may get rid of the flicker. Read in a few places that it may work but im completely clueless with it.

 

When you say flicker like flash on and off?

Are your running them with a relay or through just your stock harness?

 

Im trying running them through the stock harness right now. When I turn them on they rapidly blink on and off like a strobe light.

I did just fix the problem. I had to swap the positive and negative prongs in the connector on the bulb and now they shine bright as hell. too cold to get them all set into the housings right now but Ill post pics when theyre set tomorrow
