We basically measure their efficiency using a function of 2 indicators, which are lumens and watts. Specifically we measure the light emission of the lighting fixture in relation to its electrical power and therefore its power consumption.
The meaning of color in LED products is the temperature of light. Specifically it defines how cold or warm is the light emission. This temperature is measured in Kelvin degrees and essentially measures the hue of light. The usual color temperatures range from 2700 K (Kelvin) to 6500 K. The lowest color temperature emits what …
The color produced by the LED chip of each fixture, even if it has the exact same characteristics (3.00k or 4.00k), is likely to differ from product to product.
Viokef products that are LED integrated (not LED bulbs) have a lifetime of 50,000 operating hours. The operating hours refer to the LED chip and not to the lifetime of the product. All our products are covered by a two-year guarantee.
All our products are specially designed to be capable of LED lamps. Some of our products do not need light bulbs as they include LED integrated circuits.
