What color light do these put out? Is it more of a warm yellow or bright white?

This is just the housing. You can put in any H4 bulb you choose to install.

The light seems to be a bright white. The bulbs can be changed to your liking.

On the lighting facts label look for the K number (Kelvins, which means color temperature). These are 2700K...a warm-white which is the "yellow" look you mention. The higher the number, the whiter and less "yellow"the light gets. 5000K, for example, is very, very white, almost blue-white.

They are definitely warm white. I put them on the columns in front of my home and they near perfectly match the warm white icicle lights previously purchased from my local Sams Club.

In my opinion they are very bright yellow to white in color. There is a YouTube video titled Philips VisionPlus and mine look like that too.

The light is very white, CRI is unknown. Light distribution is very even. We used three of these lights to light up a sign from 5 feet away, the front of the church sanctuary from 30 feet away, and most of the front of the church from about 60 feet away. I will buy many more of these lights. Btw, they worked great to -10 deg F this winter

AS noted below, the White in the RGB (Red, Green, Blue) isn't a true white. However, Amazon offers OLS kits in Bright White and Warm White. Amazon's number for the Bright White is B002CQ0GYA. Warm White is B004ZO3BSK. My eyes aren't very good, so I need A LOT of light. They are pretty bright and the bright white and warm white have similar features such as 8 dim / bright settings. Plus On / Off. The warm white is around 3000 to 3500K temp. Bright white is 6000K to 7000k. Hope that helps.

It is a cool bright white (maybe slightly blue-ish). Definitely not yellowish at all. I really like them. They are brighter than I expected.

It is white with a very light blue hue. The light is definitely white. They are strictly for decor and offer enough lighting so you can see where you are going. On a scale of 1 to 10, 10 being the brightest, like a small flashlight bright, I would say they are a 10. Hope that helps. They are beautiful and very appropriate for landscape lighting and walkways. I love them and will be purchasing more for the spring.

The ones I received are definitely white. I have had others that are yellow. Quite a difference.

Just re-checked - they are white; and they are just fantastic! Bright light just where you need it.

Warm white is more like an incandescent lamp, slightly yellowish. I'm no expert, but I have another LED with 2700K; it's slightly yellow. The lamp in question is not at all yellowish, nor is it as blueish-white as the fluorescent tubes I have as my main ceiling lights near this one.

They are about the same brightness, but I think they are a more white color of light. The original lights seemed to have a slight yellow tint. I like the color better, the best thing is that they stay cool to the touch and draw much less power.

My guess would be neutral white. I do not notice any warm yellows or cold blue tinges. A typical white LED found in most LED flashlights. edit 2/13/2012 I bought more of these bulbs and had an interesting experience. The bulbs are white in my angle head GI flash light but a bluish in my Maglights. It may be a function of the lens and reflector. MY Black and Decker Snakelight shows white also.

More yellow..I put a 200w bulb in and it is works much better in a smaller studio such as mine.

This specific set lights up white. There is a different type with similar styling that lights up yellow and you can tell by the different tint on the lens in the pictures.

They are actually 865 lumens. I like the 4000k bulbs, I am not a fan of the yellow look. The cool white also tend to give the room more of a daylight look I find.
