Determining LED Rated Life A Tricky Challenge DigiKey

WebBased on this, we can now calculate how long will a 200 Ah battery be able to power an 800 W 240 V air conditioner: 200 Ah Battery Life = 200 Ah / 3.33 A = 60 hours. As we can see, because the amp draw is halved, the battery life is increased. That’s because an 800 W air conditioner on 240V requires fewer amps than an air conditioner on 120V. WebAll LED bulbs are subjected to rigorous testing to determine their average rated life. As part of this testing, the LED chips used within a bulb/lamp are illuminated and, under careful observation, their lumens output is continuously measured.
