I have used the 450 w vivo Sun LED light now for two grows as long as you follow the included directions it works great. I was using t5 500 w grow lights and these are tripled my yields just have to watch the light distance so you don't get light burn Great light otherwise. I will be looking to buy another one shortly to add to my setup.

I have had nothing but fine performance from an assortment of Vivosun lights from 100w to 450w and all work fine. I have this 450w in 1/2 half my 4x8. I find that heat has not been a problem with any of the afore mentioned lights. The VSFL6450 a pretty good light so far as this is the first grow for this light, which hangs in 1/2 of a 4x8 tent. I some times run 3 tents so I need 8 lights total and 6 are Vivosun. The VSFL6450 creates more heat than is desirable and I don't find any benefit from the detachable heat sink without an extension cable that I can't find.

This is a really nice light, a rockstar of lights if you will. The light bars are removable and it was very easy to assemble. the light has a nice solid feel to but its not too heavy for my tent. This light is even compatible with the Vivosun HUB system. On top of everything else this light is doing a incredible job of evenly lighting my girls with a variable light dial to boot. I think anyone currently looking for a light option for your 4x4 or bigger should really give this light a serious consideration.

This light is energy efficient, very well made, has easy to follow instructions and works well with my Vivosun grow tent setup. It connections to the controller and covers all of the growth stages.

Very good product and light with a lot of adjustable features. Really brought out the best out of my plants and has the nice UV feature included in the light bar. Would highly recommend and would possibly buy another one if need to

The media could not be loaded. I've now run this light for 2 full grows, and I feel comfortable leaving a review. I've used a few other lights before, and let me tell you this light is going to really boost, you're home growing power and harvest. I've run a 6 plant 5 gallon autoflower grow, and I've grown out a photoperiod 6 plant phenohunt of EG's Next Level, both in a 4x4. From both grows I've achieved over 1 lb of dried medicine. It does run a little on the warm side, but most experienced growers are masters of dealing with heat. So have a vent fan! But this light is strong, and capable of getting a great even spread of light for you canopy and the light penetration is great with it having multiple light bars giving overlapping zones of coverage. Happy growing fellow growmies.😀
