Hello There, the delivery took a while. I have for the interior lighting lamps ordered in an RV. The old with the bulbs and the LEDs in and ready !!! If everything works without problems. All lamps have worked. The light is brighter than the 21 watt bulbs, but the light is quite "cold". But that is a matter of taste. As interior lighting in Womi no problem, as the illumination at the car well not permitted. Greeting Rainer
