If you've spent most of your adult life buying incandescent lights you're probably pretty comfortable choosing led light by its watts rating.
LED bulbs have come along, though, and introduced the lumens rating. Lumens and watts are different, which can make it harder to figure out what type of bulb to buy.
Luckily, it's simple enough to sort out any confusion.
.Picking the right bulb
The easiest way to figure out what bulb you need is by using an incandescent/LED conversion cart.
Say you normally use a 60-watt incandescent bulb, for example. You would probably want to choose an LED linear bar that uses 8 to 12 watts and has a lumen rating of 800 to get the same illumination. This conversion chart will help you find an LED bulb similar to the incandescent you've been using:
As you can see, with LEDs, the amount of wattage you'll need varies for each lumen rating. This is because some LED brands have created bulbs that offer more lumens for less wattage. For the best energy savings, Energy Star recommends that you find a selection of bulbs with the most lumens you need, and then choose one with the lowest wattage.
