Beam distance and shape: For around-the-house or running use, your best option is a thinner beam.(Running a 400-lumen headlamp at 200 will also make the battery last longer.) We looked at headlamps that offered at least 200 lumens (except for the headlamps for kids). Based on our experience and research, we’ve found you don’t need more than 300 lumens for everyday tasks, and often 200 will do just fine. Lumen count also doesn’t tell you much about the actual light quality, either: From an optics perspective, the beam length and the shape both impact a light’s output more than the lumen number. However, there is the trade-off with weight, low run-time, and price,” said Victor Kabo, the co-founder of Bookman Urban Visibility, a Swedish company that makes bicycle lights. “A lot of lumens can be attractive to many and feel fun. But when you’re buying a headlamp, you don’t want to just go for the highest lumen count possible. For reference: 1 lumen is 10 times brighter than moonlight a flashlight offers about 20 lumens. Lumen count: Lumens are a measure of the quantity of light emitted from a light source.(If you want to save a little money, the discontinued Spot 350 is still a good headlamp, if you can find it.) As of 2023, you can also buy an add-on rechargeable battery for the Spot. The Spot 400 weighs 3 ounces, has a lock mode, and is weather-resistant.Īlthough headlamps with brighter, higher-quality beams exist, none offer the same combination of brightness, simplicity, and reliability at such a low price. It has a red light (for night use), a “proximity” floodlight (for a wider field of view), and strobe options (for throwing an emergency signal). The Spot 400’s two top buttons are intuitive to use you’ll have to experiment with clicking through the various modes, but the learning curve is fairly quick. The Spot has been at the top of our list since 2012 because it’s reliable and bright enough to light the way in most situations, indoors or outdoors. In your dining room, you'll want about 30 lumens per square foot on your dining table (you want enough light output to see your food, but not examine it), so if your table is 6 x 3 feet, that's 540 lumens.Whether you’re car camping or digging through a closet, the Black Diamond Spot 400 provides exactly what you need: a bright beam, easy-to-navigate buttons, and long-lasting battery life. However, if the light fixture is a lamp with a shade, you'll need a bit more. That's 200 lumens each (50 lumens x 4 square feet). If you read on your couch and need more light output in that area, you'll need about 4 square feet of task lighting on each end of the couch. For the average living room of 250 square feet, you'll need 5,000 lumens as your primary light source (20 lumens x 250 square feet), equivalent to about five 100 watt incandescent light bulbs, five 23 watt CFLs, or eight 10 watt LED bulbs. 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.
