I vouch for www.VLEDS.com
. eBay ones are cheap and look purple or bluish-white. Every time I see a car on the road at night with cheap eBay LEDs or autozone LEDs I can't help but to think about how poorly the LEDs look. They are advertised as "Pure, Hyper, Xenon White" but yet they do not look white. They look Bluish-White or some even look damn near Light Purplish-White.
If you want TRUE 5k PURE CRISP CLEAN WHITE than you have to get it from V-LEDs... If you want cheap LEDs that claim they are "White" but are really 6,000k-6,500k range than go for eBay.. Also VLEDs use 5050 SMD style LEDs. 5050SMD is better than 3528..
However, there are very few eBay sellers that actually do sell pure white 5k LEDs that are also 5050SMD style. Those are rare and hard to come by and most of the sellers don't even specify in the description if it's 5k or 6k
The ones you posted in the picture below even looks bluish-white... I would never put those on my car. They look like you paid $0.99 for them.
And no, it's not your "camera" that makes the picture look purple/bluish-white. It's actually the color your LEDs emit. Those who are unfamiliar with the differences between 5k and 6k will say 6k looks white when actually no it does not.
This is how pure white should look..
Here's a picture of my 5K LEDs in my back seats compared to my eBay "White" LED strips.. Both are advertised as white, but honestly do you really think those LED strips look white? They are more Purplish-white..
It's possible to get 5K Pure white LEDs on eBay, but nearly 75% of eBay sellers only have 6,000k+ LEDs..
