![]() ![]() Incandescent, CFL, or LED Lights: Which Bulb and How Many?ĭetermining which bulb type you would like and which ones to purchase to ensure a sufficient amount of light depends heavily on the square footage and purpose of the room. Tables and Raised Surfaces: 30 Lumens per Square Footĭesks and Task Lighting: 50 Lumens per Square Foot While that above definition of lumens is helpful, you're probably asking, “So, exactly what number of lumens do I need to light up my room?” The answer will vary based on the design and color scheme of your room, but here is good rule of thumb, loosely based on the IESNA Lighting Handbook: Why is this? It's because the brightness of LED lights is determined by lumens, not wattage. Or, other times, you may end up with a bulb that's so bright that it practically blinds you. In many cases, choosing an LED bulb based solely on the stated wattage equivalent will leave you with a bulb that is nowhere near as bright as the one it's replacing. However, if you opt to upgrade to newer lighting technology such as LED light bulbs, you'll need to get rid of any notions you have about wattage or incandescent equivalencies. The higher the wattage, the brighter the bulb. This is because incandescent bulbs' brightness is base on its wattage. If you are buying another incandescent bulb, which is getting harder to find these days, then looking at just the wattage is fine. Many people mistakenly assume that they need to look solely at wattage when buying replacements for incandescent bulbs. No, you may not even be sure which funny-looking 60-watt equal light bulb you need. Long gone are the days of throwing your favorite brand of 60-watt light bulb in your cart and being on your way. If you shop for light bulbs in a store today, you may find a couple “full spectrum” incandescents or halogen floodlights, but other than those, compact fluorescent and LED bulbs line the shelves. In recent years, household incandescent light bulbs have given way to new, sometimes unfamiliar technologies. ![]()
