Where natural ambient light isn't enough, its powerful LED light elevates shots to a higher level. Whether used in conjunction with smartphones, digital cameras or action cams, the Lume Cube 2.0 is absolutely brilliant in its simplicity. It is the ideal, space-saving flash or continuous light for photo and video shoots. It's here, the new generation of the powerful clever LED light cube: Lume Cube 2.0 - The already ingenious light power dwarf Lume Cube has been perfected once again. Long-lasting, eco-friendly and super energy efficient…what’s not to love? LED bulbs are fast becoming the coolest light bulb of them all-literally, as they emit almost no heat and they thrive in cold locations.Lume Cube 2.0 Single Light LED Light Cube And, yes, there are many that create that same wonderful, warm glow of the incandescent we’ve known and loved for a century. The LEDs now on the market are available in an amazing array of sizes, colors and shapes. Department of Energy estimates a collective household savings of $3 billion dollars nationwide-each year. There are serious, measurable benefits to these changes. These federal regulations first applied to 100W incandescents (in 2012), 75W bulbs (in 2013) and 40-60W bulbs (in 2014).Īs of 2023, incandescent bulbs will be phased out completely from the American market. Since 2012, federal laws have gradually required the common types of light bulbs to be 25% more energy efficient. The other 90% is heat-aka unused (essentially wasted) energy.Ĭoncerned about this significant waste of energy, the federal government set out to change regulations on light bulbs, requiring them to be more efficient. The problem with traditional incandescent bulbs is that only 10% of their energy goes toward the production of light. Rely on new bulb labeling standards to show lumen output and help you choose the right brightness for your needs. On the low end, replace a 40W bulb with an LED bulb of about 450 lumens. As a rule, you’ll replace a standard 75W bulb with an energy-saving bulb of about 1100 lumens. LEDs use much fewer watts than incandescents with the same brightness. Lumens equal brightness watts measure energy used. Pure white light hovers around 4000K, while cooler temperatures that simulate daylight are 5000K or higher. So, if that’s your preference, look for LEDs with light color temperatures in the 2700K to 3000K range. The warmer light colors associated with incandescents are on the lower end of the scale. On light bulb labels, you can find the bulbs’ color temperature, measured on the Kelvin scale. Our LED bulbs and fixtures are 90 or above, with a few 80 CRI exceptions. A really good one is 90 or above, which is an excellent choice for bathroom vanity lights. A good CRI for most indoor residential applications is 80 or above.

All old halogen/incandescent light bulbs have a CRI at or near 100, which is the maximum and roughly equivalent to full daylight. The color rendering index shows how true colors are displayed under a light source. Look at the bulb’s Color Rendering Index (CRI). Lighting experts currently recommend only buying Energy STAR-qualified LED light bulbs, as they must pass numerous quality tests to earn that designation. As manufacturers rush to fill the market with LED bulbs in the wake of changing laws, watch out for cheap fixes-if it seems too good to be true, it likely is. Newer bulbs have a Lighting Facts label that will give you all the details of a particular bulb:Įspecially in LEDs, the manufacturing quality of the bulb varies, with lesser bulbs not lasting as long as their better-built counterparts. For example, while we’ve previously looked to watts to learn a bulb’s brightness, that information is now presented in lumens. How do I read the light bulb label?Ĭhanges in lighting regulations and technologies mean that there are new lighting terms to learn. Additionally, you can use the color temperature chart to help you in choosing the best lighting for your application. This should provide you with a good understanding of how bright 120 lumens is vs. Use the chart above to determine exactly how many lumens are in a watt and vice versa.

See how to measure lumens below: How many lumens do you need? With new, energy-efficient LED technology, we can no longer rely upon wattage to indicate how bright a bulb is. Not that watts are bad, but they measure energy use, not light output. The definition of lumen is: “a unit of luminous flux in the International System of Units, that is equal to the amount of light given out through a solid angle by a source of one candela intensity radiating equally in all directions.” What is a lumen? How is it different from a watt?
