Side by side comparison picture so you can see the difference.

I've installed some warm white and cool white LED lights ( which are replacements for the wedge based 921 incandescent bulb ) in our RV.

The neat thing is that they are installed so that I could get a great picture of both at the same time to get a comparison. I spent quite a bit of time color matching with my camera so that the picture looked almost exactly the same as the scene in real live.

Some quick notes on the LED lights :
* They are very high efficiency LED lights that have a wedge base.
* Each replacement light has 10 individual LED's on it ( This is a HUGE hint if you want the LED replacement to put out the same light as the 921 it replaced ).
* My wife and I both like the cool white a little better.
* The LED lights have 10 LED's that all project in one direction. This lighting application is solely a 180 degree application.

Now you can be the judge.
