I have to quote 300 pcs of 8" commercial downlight conversions plus 40 pcs with an emergency back up. The customers asked for 23W, so I guess we can use your 27W. 4000k, 0-10V dimmable. Please give me lead time and terms as well. Thank you very much, Olaf Haas

I just heard back from our customer. They installed all the lamps (720 if I remember correctly) and they were extremely happy. Not a single failure! Great job to everyone that designed and manufactured these products. You are our commercial downlight line!
