How many watts should a light bar have?
Light bars have a variety of options. Higher quality products can have fewer watts and put off more lumens. The lowest amount of watts for a standard light bar should be around 120 watts and a good one should be in the 240-300 range.

ABOUT UV&IR

UV can increase THC yield,but it will also shorten lifespan of silicon and plastic parts on LED,so we do not suggest to add single uv diode directly in the fixtures.
lR is used for control the process of growing with 730nm.
The SUNLIKE diode we adopt is a full spectrum LED including all wavelength of sun. It emmits white color but include the UV and lR which don't destroy the LED chips.

PVISUNG LED GROW LIGHT

1.When the light intensity is exceeded light saturation point , the plant is saturated, the protoplasm of the plant is destroyed,the detailed spore loss is excessive, and the photosynthetic action is weak.
2. When the light intensity drops below light compensation point, the photosynthetic action of plants is weak, and the botanical society withers.
