Original Crees are excellent lightbulbs. They are so expensive that some seem to want to replace the old bulbs with original Crees. The package I received for this order was genuine. However, as a precaution, other Crees 100W lamps purchased through Revain were not presented in this form. Completely exchanged for another bulb. Lightbulbs didn't work, they were dust and cobwebs. One even had a dead bug in it!
