Qualität die wir beanspruchen lässt auch Lieferanten nicht kalt:
Letzte Frage an Lieferanten bevor wir Muster bestellen:
Thank you for the Analysis for the LED of the LED-Tubes. Because we only bay 50 Tubes for sample we would like to know more about the Quality. If the LED inside the Tubes are too high loaded (to high = 100%) the quality is low. There exist two system of electronic control of LED. Current-stable or Tension-stable control. What kind of power-supply do you have in the Tubes. To which level are the Tubes loaded with energy? 60% 80% 100%? The lifespan of the Tubes refers to the Level of load of the single LED.
This is part of the Entrance-Check, we do with unknown Products in our Company. Can you give us any information to that item, perhaps in relation to the light-output (Lumen) of the Tubes. The result of that Analysis defined the Quality-level in sales for Necono AG.
With the best regards
Antwort des Kunden:
You are so professional in LED lighting products.
We use current constant driver not voltage constant driver for the LED lighting, as the current constant is better for LED lifetime.
The power of all LEDs is about 26.4W and the driver about 3.6W (driver efficiency 88% ). We use 216pcs 2835 LED for the 30W T8 LED tube light, so the power of each 2835 LED is only about 0.12W (26.4W/216). We only use about 60%load of each single LED to guarantee the long lifetime and extra high lumen 160lm/w.
Please do not worry about the lifetime and quality of our LED tubes. We are really professional in LED lighting and export more than 50,000pcs LED lighting to over thirty countries each month.
