I have two waveform 6500k four foot T8 bulbs in a standard fixture. I was given a 4ft T5 fixture with four regular 6500k bulbs. Absolutely no comparison between the two. The plants under the waveform were larger, greener and healthier under two light bulbs than the same plants under the four T5 bulbs. A distance of several inches must be kept between the T5's and the plants or they will burn from the heat out put. I had plants touching the waveform LEDs with no effect. I will be purchasing the waveform 6500k T5 LEDs for the T5 fixture. Truly a excellent product.
LED Grow lights work as advertised. I purchased these lights for starting seedlings indoors. A great improvement over the T8 fluorescent lights that were replaced. It is remarkable the difference in the amount of light delivered. Shipping was fast too.
I purchased the 6500K LED grow light tubes for starting seedlings indoors and they are working out fantastically. The shipping and delivery was smooth. Product arrived in a timely fashion in excellent condition.
Purchased these lights to replace some old grow lights, and am impressed with the amount of light they emit. The seedlings in the trays are really responding to the intense light, and have doubled in size since the lights were installed. The tubes are mounted in fluorescent light fixtures in which I removed the ballast transformers, and not only is the light more intense but the hum of the light fixtures is completely gone. Looking forward to the long life of these tubes for raising seedlings.
