Each bulb was packed in a separate box and then 4 boxes were packed in a large box. The large carton was then packed into a shipping carton with labels. I don't know what else they could have done to ensure they arrived in perfect condition. Guess what . they arrived in perfect condition. The light emitted by these bulbs is amazing and you feel like it is daylight inside. I use them in a $6 metal clip on lampshade from Home Depot, which works well. We either use them to grow herbs or we use them on a photo shoot to sell something. I can see that they work well in any daylight.
