1. LED floor lamps have different brightness (MCD) and different prices. LEDs
used in LED lamps should comply with laser class I standards. Anti-static
ability LEDs with strong anti-static ability have long lifespan and therefore
are expensive. Generally, LEDs with an antistatic rating greater than 700V can
be used in LED lighting.

2. LEDs with the same wavelength have the same color. If the same color is
required, the price will be high. It is difficult for manufacturers without LED
spectrophotometers to produce products with pure colors. Leakage current LED is
a luminous body that conducts electricity in one direction. If there is reverse
current, it is called leakage. LED ground lamps with large leakage current have
short lifespan and low price.

3. LEDs with different lighting angles and uses have different lighting
angles. Special lighting angle, higher price. Such as full diffusion angle, the
price is higher. The key to different qualities of life is life, which is
determined by light decay. Small light decay, long life, long life, high price.
The luminous body of chip LED is a chip, and the prices of different chips vary
greatly. Chips from Japan and the United States are more expensive, and
generally the prices of chips produced in Taiwan and China are lower than those
from Japan and the United States (CREE). Chip size: The size of the chip is
expressed in terms of side length. The quality of LEDs with large chips is
better than those with small chips. The price of LED energy-saving lamps is
directly proportional to the size of the chip.
