AODE® 2x A Pair 39mm 3W Super Bright White Car Truck Vehicle COB LED Bulbs Festoon Interior Dome Map Lamp Front Number Plate Light 130188
Very bright, even, white light.  I love the even panel-like output of light from COB LEDs.  These were a little expensive when compared with standard SMD lights, however it was worth it for my application.  These have a little metal heat sink fins on the back to dissipate heat from the LEDs -- seems like a durable, smart design.  I don't have any feedback as to their lifespan yet.
