![]() ![]() You’re probably familiar with color temperature terms like warm white, cool white, or daylight. In practical terms, it tells you how yellow (warm) or blue (cold) a “white” light may be. Color temperatureĬolor temperature reflects the warmth or coolness of a light source. ![]() LEDs have CRI ratings that range from 80 for standard LEDs to over 90 for high-CRI LEDs. It’s a number from 0 to 100 that measures how accurately a light source reveals the true colors of objects compared to natural light, with 100 being the most accurate. CRI ratingĪ number you may notice when shopping for LED lamps is a CRI rating. A brightness of 450 lumens is adequate for most desk lamps, but for some detailed tasks, like drafting documents, crafting, or aesthetician services, 800 or even 1000 lumens may be necessary. The brightness of any lamp or light bulb is measured in units called lumens. Task lighting needs to be brighter than ambient or accent lighting. And LED desk lamps tend to have higher upfront costs than other lamps. Some aren’t designed to be user-replaceable at all. Many LED desk lamps have built-in elements that are a lot harder to replace than simply screwing in a new bulb. What to think about when choosing an LED desk lamp Drawbacks to LEDs Still, LED, fluorescent, and halogen bulbs often show their equivalent incandescent bulb wattage. The wattage of an incandescent bulb used to be the primary way to distinguish how bright a light was, but fluorescents and LEDs use less electricity for the same amount of illumination. If you’re in need of a desk lamp, an LED desk lamp should be high on your list. Compared to other lighting technologies, LEDs are versatile, eco-friendly, and more economical over time. While early LEDs used for lighting got a reputation for giving off cold, impersonal light, LEDs today can produce light in almost every possible color and white light at an array of temperatures, from warm yellowish to cool blueish. Unlike most fluorescent bulbs, LEDs can be dimmed, and unlike halogen bulbs, they don’t get very hot at all. (For the sake of comparison: A traditional incandescent bulb usually lasts from 2,000 to 5,000 hours.) LED elements often boast a lifespan of 50,000 hours, which means 10 or even 20 years of use. They use 75% to 90% less energy than incandescent bulbs of comparable brightness and last much longer before needing replacement. LEDs, or light-emitting diodes, are tiny semiconductors that emit light when fed an electric current. Like more traditional desk lamps, LED desk lamps illuminate the surface of your desk for reading, writing, and other work activities where a bright, adjustable, directional light is required. A LED desk lamp is a task lighting fixture that uses LED elements to produce light. ![]()
