    Light for 27"x27"x63" Grow Tent

    LED wattage question

    Curious to know if there is any difference between choosing a 5 watt LED vs a 3 watt LED. The 5 watt LED has 120 bulbs and the 3 watt LED has 200 bulbs. Each totaling the same wattage and pretty much the same light spectrums. I thought I heard the 3 watt LED was better. TIA spy
