Sonneman Ultra Slim Long Wall Sconce

The web page specifies the fixture comes with four 50 W halogen bulbs. the units I received (four) all came with four 40 xenon bulbs. We are using these fixtures on either side of our bathroom sinks and are disappointed with the lower light output. From what I can learn, the light output for G9 halogen 50 W bulbs produce more that twice the number of lumens of 40 halogen bulbs. I also found that halogen and xenon bulbs have equivalent lumen production. Xenon bulbs have a much longer usable life. Wayfair never contacted me to see if the 40 W bulb would be acceptable. I have requested their assistance to resolve the problem. I purchased dimmers to use with these light fixtures before installing the fixtures. No need to use the dimmers! I will say the fixtures are very attractive and would buy them again if they had the light output specified in the description.
