Ok so i have my 99 f-150 with the oxford white
and right now i have the 8k HIDs with the chrome reflectors behind
i found some nice black out covers but im not sure if i should upgrade to the 10k or stick with the 8k. any suggestions?
thanks

 

Switch to 4300k or 5000k. Best light output and doesn't look all ricer. Add some projectors too.

 

8-10K lights WITH smoked covers? I hope you don't do any driving at night....

 

im pretty sure you need to read into hids a little better. switching to 10k would be a DOWNgrade.

 

depends on how old you are

Around here, high-schoolers think the K temp is how cool you are. I think Mr. 30,000K is in the lead.

 

would still be brighter than stock....but yes it is a down grade

 

Brightness should not be confused with luminance. Yes they might have more lumens but brighter? No.

 

lumens is the power of light perceived by the human eye....so yes

 

a 35W 10,000K HID puts out about 1,900 to 2,100 lumens (depending on the quality of the factory). Looking at a few headlight covers, one of them lists a 35% VLT percentage.

2,000 x .35 = ~700 lumens

A stock 9007 bulb puts out about 1400 lumens (low filament). Even figuring a 3+ year old halogen bulb with OEM 10th gen housings, in this case the halogen would be brighter than the HID with covers.

 

The high kelvin HID will still look brighter to oncoming traffic due to glare even if luminous output is less. Performance wise, it will obviously be worse than the halogen. Its just an all around fail.

 

you sir are very very wrong. doesnt everybody know "hyper deep blue" is the best and brightest?!

theres a guy that tried telling me he had hids that he could adjust the amps on and the bulb goes from 6k to 12k and the 6k is pretty bright but the 12K would "burn through trees" and you could see for miles! i just started laughing and shook my head

in case everybody was wanting some of the super cool hyper deep blue, heres a link to an ebay seller that carries them. lol hyper deep blue bulbs

 

I work for a car shop and we were told by our HID distributor that the "K" reading has to do with the color not the brightness. We primarily carry the 35w HID kits but we have installed some 50 watt kits. The 50 watt kits are much brighter imho. If you want a brighter HID bulb get a higher wattage simple as that.

We just installed a 35watt 8000K kit on an 08' Super Duty and he wanted headlight covers and I will say they did cut down on his lights significantly. If you are going to put headlight covers on I would highly suggest a 50watt or higher kit.

Also keep in mind that the closer you keep to pure-white the brighter everything will seem. It seems that around here 8000k has been the best combination of pure-white with a slight blue tinge to cut through foggy conditions.

I have a 97 F150 with 8000k 35watt lights and my dad owns a 03 F250 with 6000k 35watt lights and he clearly outshines my lights on clear nights but in foggy conditions mine seem to cut through fog better.

 

4300k or 5000k have the highest lumen output, 5000k being slightly whiter. 3000k-4000k is best for fog. 6000k+ you are really losing luminous output and gaining color. 50w kits are brighter when comparing the same kelvin bulbs, but a 35w 4300k kit will outperform a 50w 10000k kit with ease.

Headlight covers are like a bandaid to a gaping cut...just use projectors.

 

your math is wrong

should be

2000x.35=700 then 2000-700=1,300

 

I stand corrected. It's too late for me to be doing math

lower Kelvin pierces water better than higher
