- Technical features of the device.
- Temperature allowed for operation. Most often, the packages indicate the interval from -40 degrees to +40 degrees.
If the buyer understands the marking of LED lamps, it will be easy for him to choose the device. The purchased product will serve for a long time.
Differences between indoor and outdoor products

LED lamps can be used instead of fluorescent ones thanks to a tubular bulb. Such connections are marked G13. Lamps marked GX53 are provided for the ceiling.
Whyis it important to choose the right light output and color rendering parameters?
For human vision, the correct organization of the supply of light is necessary. Of great importance is the transfer of the color of the object on which the light falls. You need to choose the appropriate color rendering index. The strength of the luminous flux also affects the supply of lighting.
Color reproduction is responsible for ensuring that the lamp correctly reproduces the natural colors of Ra. The luminous flux is responsible for the lighting power. It is usually measured in lumens. On each package, manufacturers write the luminous flux of the lamp. It is usually higher for LED light sources than for standard lamps. It must be remembered that the brightness of the LED source decreases as it is used.
