Pay attention to how to choose a right LED grow light?

As a professional team,we have a good judge of genuine and fake lights.We’d like to be honest and sincere to guide you to choose genuine and good light.

1.Pay attention to actual power rather than output power

High output power described in title or parameter not means the light has so high power draw indeed.Actual wattage is what matters.Please beware 300W/800W(true watt 180w only)/900W/1200W(true watt 180w only)/1600W(True watt 220W only)light listed with high output power but with low true watt.

2.Beware fake 6w or 10w

5W is highest watt of LED chip in the current market, 6w or 10w is not existing at all.

3.Impossible for high lumen with low power and bad chip

If seller lists high lumen but low power and bad chip,like 300w with over ten thousand lumen,unbelievable!

*Dear friend,please DO NOT be misled by these fake and exaggerated information.Sharpen your eyes and choose genuine and good light,let your money well spent and plants healthily thrive.

Please read Full Description carefully and pay attention to real power draw and IR led before buying.

What kind of plants can I grow with your LED grow lights?

Ideal for all phases of plant growth, and works well with water solution and culture and soil culture. Can be used in house garden, pot culture, garden, sowing, breeding, farm, flower exhibition, bonsai, green house, water soluable breeding, greenhouse cultivation, etc.

Few leds seem to be dim? What happened?

If you find out some leds seem to be dim at first using, you should doubt that these leds are infrared leds. You can wear sunglasses to look them clearly, and actually they’re working well.

How many actual watts of power will it take for me to grow decent or high quality meds?

You should be able to get decent results with as little as 20-25 actual watts of power per square foot of grow space with the light set about 18”above the canopy during bloom.

If you want to step up your game, increase yields, and grow really thick and dense nuggets with higher resin content then you’ll probably want to be somewhere around 30 to 50 watts of actual power per square foot during bloom with the lights set approximately 18” above the canopy.

In general, the more power per square foot, the better the quality of the finished product…within reason of course.

Yes. There is such thing as too much light. Anything over 50 actual watts per square foot would likely require CO2 supplementation and heat issues would need to be adequately addressed.
