I suddenly needed a replacement bulb for our candle warmer and was confused at first because there were such packs of 3 bulbs at a great price and others where a bulb was three times the price. In the end these bulbs work great and are pretty sturdy so I expect them to hold up well. Fortunately, before it was too late, I noticed that when you reach this type of lamp, many conclude that the power is too high, but this is not very obvious. Just check the details.
