When it comes to choosing your new LED candle bulbs simply ask yourself these three questions:
1) Is it definitely a candle bulb I need?
Would a smaller golf ball bulb fit better? Sometimes candle bulbs can stick out of the top of light shades leaving them looking unsightly. Candle bulbs are usually fine, but just a thought.
2) What cap/base do I need?
There are 4 main types of bases
BC or B22 (two small prongs)
ES or E27 (large screw)
SES or E14 (small screw)
SBC or B15 (smaller version of the two small prongs)
3) What wattage do I need?
3w LED = 20w incandescent
4w LED = 25w incandescent
5.5w LED = 40w incandescent
