In general, low quality products. Primarily from china. As a contractor, I can say this is not the best place to go. I've done some level of business with 1000bulbs.com for years now. Our last project that we used 1000 bulbs as a vendor will be our last purchase. Fixtures and lamps from same manufacturer at same color were not the same color lamps. We tried different products from 1000bulbs but were not able to get a color match. Had to go to one of our regular wholesalers before we could get the situation resolved. Lots of wasted time, jobsite labor and money with minimal help or real concern from the 1000bulb staff.
