Unfortunately, this site does not allow us to attach pics to posts unfortunately, I have them attached to a post I made on RX8club.com.
I didn't want to get beyond 4500Kish since I want to have good intensity to the lights as well. When you get beyond 5K, intensity drops with regular bulbs even though the color goes toward blue. These were $25 shipped from a good eBayer.
The four pics are with the MTEC Super White on the right (driver) and the stock 9004 bulb on the left (passenger). The MTEC is definitely much much whiter than the yellow stock. But the yellow stock seems to put out a little more light/intensity than the MTEC. I wish the MTECs were a bit more intense, but I definitely like the whiter light. I guess I'll have to drive with the MTECs for awhile to decide. More later I guess.
