I only chose two stars because these lightbulbs are buzzing. I've read reviews of all of Amazon's dimmable compact fluorescent bulbs and there have been no reports of hum. I will do my best to return them and purchase dimmable LEDs for a rough equivalent. Update 10 Jun 201: More like Bulbrong. One of them exploded. I didn't use them in "dim" mode at all; The only reason I bought them was that non-dimmable bulbs are not recommended for dimming outlets as they wear out faster. It also seems to wear out pretty quickly. Again I strongly recommend an LED, even one direct from a Chinese manufacturer via ebay will likely last longer as LEDs use a completely different substrate to produce light.
