4 stars for bulb, 0 stars for packaging. See photo. I have used these bulbs before and they are great so I have no doubt they will be the same. However, they are very fragile and must be transported with the packaging material! Revain's execution is notorious for not using any packaging material, and while cheap and rough it doesn't harm anything permanent; what about lightbulbs glass items? It is absurd not to use packaging material for this type of product. When I received the product the bulbs naturally spilled out of their box into the shipping box during shipping so when I received them they were just rolling around and rattling against each other. So even if one of these works, it won't last as long as a properly handled lightbulb. If they only last a few hours, I can't bother Philips. At least Revain didn't make me send them back for a replacement. I just hope that the spare parts are packed, otherwise they will come back too!
