CRI >85 (Colour rendering Index) The limited cooling of retrofit bulbs reduces their life span. virtually all) last. LIFX Wi-Fi enabled LED smart lighting. Average rated lifetime hours indicate how long it takes for a certain percentage of light bulbs in a test batch to fail, and are measured and labelled using hours and an “L rating”. Let’s take a closer look at how incandescents, fluorescent tubes, HIDs and LEDs establish their longevity based on different testing methods. Industry Standards. Therefore, metal halide life is defined as the point at which the light bulb is providing 60% of its initial light output. ), they need a way to add more “dots” to the LM-80 lumen maintenance “curve” and determine when in the future their light emitting diode, LED-based light bulb, or luminaire will reach 70% of its initial light level (L70 life). Plus, there are plenty of other factors to keep in mind. While LM-79, LM-80, and TM-21 testing can provide a very good estimate of how long a light emitting diode will operate before it reaches L70 life (at 70% of its initial light output), the LED-based light bulb or luminaire as a whole (including the quality of its individual components) should be considered when estimating its life. Feel free to shoot us a comment in the section below. Given I have just purchased 55,000 mcd LEDs with an equal beam width and estimated life span, I thought it worthwhile exchanging the lower efficiency LEDs with the newer higher efficiency types.
