The grow light glows with an enchanting brilliance, casting a luminous spell that dances gracefully within the confines of the grow tent. It is a treasure, a beacon of light and hope, a testament to the beauty of wise investment.

So far so good.

If you use them like you are suppose to not plugging them all into each other with one plug you will be happy. They don't get hot I have them above my hydroponic system. I did make the mistake of turning them on for 12 hours each day and my lettuce grew to fast my strawberry plants loved it tho. In my opinion they are great easy to install with no problems.

I am at the end of the second week of flowering and am very happy with these lights. It is important to note that the light is ideal for a 2'x4' area max. The PAR lighting map the manufacturer shows is not from this light. Even considering this, the value of this light at $138 is fantastic. I am running two lights in each 4' x 4' growing area and am very happy. Having 600+ watts for under $280 is a fantastic deal. With two lights per 4' x 4' space, I can easily have over 1,000 ppfd when needed in the greenhouse.
Update: i added 4 photos from 3-4 weeks before harvest. For a greenhouse, these lights are ideal.
Update: The video is 4-5 days into flushing. I am very happy with the lights performance. I will continue to use these lights without hesitation. I am very happy.

Light is actually pretty good in quality nice and bright .
Pros: low heat output , quality build , full spec , 100w pull at 100%power

Cons : adjustable knob is locked to 25% increments. (Cant do 40%..) , Hanging wire is really short (non adjustable)

Overall best pick for how cheap it is . Going one month full time use and still running

I set the timer and it comes on as expected daily. My plants looks healthy already!
