Wow! Doesn't matter! These fluorescent lamps are a real find. (3) The 23w bulbs in my ceiling fans put out LOTS of bright light. I didn't rate the efficiency or durability of these bulbs because I just plugged them in. But if you need bright daylight lamps, this is for you. I only use two of the three bulbs in the ceiling fan to keep the brightness low.
