  • 1.14What's the application of LED in lighting field?

    LEDs are widely used in lighting area according to the power and type of them. For instance, low-power LEDs usually can be found in indicator panel of car dashboard or your mobible phones. Middle-power LEDs are applied in exterior lighting of cars, backlighting LCD screens and emergency lights and lamps. High power LEDs are used for illumination like flashlight, car headlights, home lighting, office lighting, street lighting etc. and high lumens LEDs belong to a complete lighting system. LONEN LED lighting devices are mainly for indoor and outdoor illumination use with medium and high power LEDs.

  • 1.15How is LED(light-emitting diode) differentiated from other lamp types?

    LED, short for Light-emitting diode, is a solid-state semiconductor device without gas, filament, glass bulb or any moving part. LED is a two-lead semiconductor light source. It is a basic pn-junction diode, which emits light when activated. When a fitting voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons.

  • 1.16What’s the standard of LONEN products?

    The standard of LONEN rechargeable LED products is:

    LED Type:

    luminous intensity: 1400-1600 MCD ; Life-span: 50000 hrs

  • 1.17The color of the light from my LED flashlight looks different than the light from the same model flashlight when I shine them on the wall together. Is one LED defective?

    There is nothing wrong with either LED. LED technology produces an unavoidably wide range of tints. The light will always be bluer than an incandescent, and there will be more variation between identical products than with incandescent lamps.

  • 1.18What’s the difference between flashlights with different lumen?

    Flashlight with higher lumens beam carries further and appears brighter light than that with lower lumens beam.

  • 1.19How can I tell when my flashlight is fully charged?

    Follow the guidelines on the package. The recharging time ranges from 8 to 12 hrs. The red light indicates a charged condition.

  • 1.23What’s the different between watts and lumen?

    Watts VS Lumen

    Watts are a measure of power draw. As LED technology improves brightness and power draw diminishes, watts are no longer considered as a suitable brightness indicator. Lumen is a measure of actual output brightness and is generally considered a better gauge.
