HID vs. LED Lighting The useful life of LEDs is typically defined as the operating time prior to 30% lumen depreciation, or 70% lumen maintenance (L70) . This level of LED lumen depreciation has been widely adopted as the standard for useful life since a 30% decline in lumen levels is not easily detectable by most people.

- How efficient are led bulbs compared to incandescent bulbs?The efficacy of the newer led light bulbs is more than five times higher than comparable incandescent bulbs. In other words, led light bulbs use only about 20% as much electricity to produce the same amount of light. However, because led bulbs direct a larger percentage of light where it is needed, in many applications they are as much as ten times as effective as incandescent bulbs, reducing energy use by 90%.

- Not only do LED holiday lights consume less electricity, they also have the following advantages: 1  Safer: LEDs are much cooler than incandescent lights, reducing the risk of combustion or burnt fingers. 2  Sturdier: LEDs are made with epoxy lenses, not glass, and are much more resistant to breakage.

How Long Does An LED Light Bulb Last? While it can vary slightly depending on the bulb, on average LED light bulbs last over 50,000 hours. That would be almost six years if left on twenty-four hours, seven days a week. In terms of usage, if you leave your light on all day (16 hours), an LED replacement bulb would last 3,125 days or approximately 8.5 years. If you leave it on only during the evening (4 hours), an LED replacement bulb would last 35 years. Comparatively speaking, both incandescent and compact fluorescent light bulbs last a mere fraction of that. LEDs last 50 times longer than a traditional incandescent bulb and 10 times longer than a compact fluorescent.

How Long Do LED Lights Last The life expectancy of the bulb in an LED flashlight ranges from 50,000 to 100,000 hours. Also, because LED lights are energy efficient, consumers will find that each fully charged set of batteries will last more than twice as long as when powering flashlights with incandescent bulbs.ctually, the answer is dependent on the type of the LED light that is being used.

CFL vs LED: The energy saving light bulb debate is over LED bulbs save you energy and money by using less Watts to give you the same amount of brightness. With LEDs the way to measured brightness is not with Watts but with lumens. The more lumens, the brighter the light.

Why people still use inefficient incandescent light bulbs Incandescents are inefficient – 90% of the energy goes toward heat and only 10% toward light. Incandescents also don't last as long as CFLs and LEDs. The typical incandescent bulb lasts about 1,000 hours, while a 15-watt CFL bulb lasts 10,000 hours and a 12-watt LED bulb lasts 25,000 hours. In other words, incandescents last about a year while CFLs can last 10 years and LEDs up to 25.

- And it is now 15 days after the party, and the LEDs are *still* glowing. Here's some things to keep in mind when using this great product: - They are not brilliant, that is, the light is not strong. It is a single LED (powered by two batteries, hence the long life) and easily overcome by indoor lighting.

- Unlike incandescent and fluorescent light sources, Cree LED Lighting products produce virtually no light in the ultraviolet (UV) or infrared (IR) spectrums. Useful life has been defined as the number of hours an LED device can operate until it emits only a certain percentage of its original lumen output.

CFL Fluorescent Light Bulbs: More Hype Than Value If you try to leave the light on longer so the bulb will last longer, the electricity savings are then lost. A more accurate longevity statement would be 250 to 10,000 hours depending on use.. In an episode of Mythbusters, a group of different light bulbs are turned on and off every two minutes for six weeks.

LED Life Expectancy These have an average life time of around 1 year, if used regularly. Capacitors are part of the circuit in every LED driver. Now a number of companies are making their capacitors from ceramics, giving them a much longer life expectancy.

- Energy efficient - LED’s are now capable of outputting 135 lumens/watt. Long Lifetime - 50,000 hours or more if properly engineered. Rugged - LED’s are also called “Solid State Lighting (SSL) as they are made of solid material with no filament or tube or bulb to break. No warm-up period - LED’s light instantly – in nanoseconds.

Understanding the difference between LED rated life and lumen-maintenance life (MAGAZINE) The combination of lumen-maintenance life (Lp) with statistically-measured failures (Bp) is the LED light source’s rated life, or BpLp value. For example, if an LED light source is claimed to have B50L70 of 30,000 hours, then 50% of tested samples should have a lumen-maintenance life of 30,000 hours. Ideally, to obtain the rated life for LEDs, the statistical failure measurement can be integrated with lumen-maintenance measurements during the life test.

LED buying guide For instance, a 10W LED that puts out 800 lumens of light (lumens are units of brightness for a light source -- more on that in just a bit) will add about $1.20 per year to your power bill if used for 3 hours a day at an average energy rate of 11 cents per kilowatt hour (kWh).

Learn About LED Lighting Lifetime of LED Bulbs. The useful life of LED lighting products is defined differently than that of other light sources, such as incandescent or compact fluorescent lighting (CFL). LEDs typically do not “burn out” or fail.

Longevity of light bulbs and how to make them last longer The life of a CFL is significantly shorter if it is turned on and off frequently. While you may not turn your light on and off every 5 minutes, a 5-minute on/off cycle the lifespan of a CFL reduces its lifespan to life of an incandescent light bulb.

- Cheaper ILBs last 750 to 1,000 hours or less than a year of normal usage. Long life span ILBs can be up to 1,500 to 2,000 hours, but they cost a lot more. Still, they last only about 2 years with normal use. Fluorescent & CFL Lamps. Fluorescent lights and compact fluorescent lights (CFLs) have a similar burn out scenario as ILBs already discussed.

- The new standards also require a minimum-rated lifetime (how long the lamp typically lasts before burning out) of 1,000 hours compared to 750 hours. that is typical now. For now, these standards apply only to “general service” lamps. Specialty lamps like rough service lamps, 3-way lamps, and others are exempt.
