Utility of the electric current just like accelerator of a car, the harder you step on gas, the faster you will be, you can’t make it 430km/h when the car limits on 250km/h. All electric devices work the same even LED light. The higher input current, the more brightness it performs. But there is a limitation. You cross the line the LED light go wrong.

And color temperature is usually described as Kelvin. Generally speaking, incandescent is 2500-4000 Kelvin (warm white, yellowish white), sun light is 6000-6500 Kelvin (neutral white, the best lighting reveal actual objects) another white is 10000-12000 Kelvin (cool white, bluish white, it gives people an image of pale and cold).

When we sourcing lighting fixture for advertising light boxes, we have to consider what emotions we get from the graphic, graphic design is one thing, color temperature is another. Warm white transmit a feeling of old school, classic.
