How to choose the right LED bulb
LED bulbs come in a number of shapes and sizes. To guarantee a good fit, start by checking the shape and base type of the bulb you wish to replace. Next, check if your fixture is dimmable. When in doubt, take a photo of the bulb you wish to replace, or bring the bulb to the store.
Instead of thinking about light bulbs based solely on the amount of energy they use, focus on their brightness level. Lumen is the measurement of brightness. Higher lumen bulbs produce a brighter light. Watt (W) is the measure of power consumption. Lower wattage bulbs can lower your electric bills.
A light bulb’s color temperature, measured in degrees Kelvin (K), lets you know what the appearance of the light produced will be. Understanding Kelvin temperature makes it easier to choose lighting that gives you the look and feel you want. LED bulbs can produce a wider range of color — from warm (2700K) to cool daylight tones (5000K).
