This grow light is amazing, the light is bright and my plants absolutely love it, they’re growing unbelievably fast under this light during winter! The light doesn’t get hot, however it still gets warm but not enough to burn your hand. Overall if you’re looking for a grow light, look no further as these are amazing and at a very good price!

Time function is great and easy to use. This is my second time buying, got one two years ago for my living room and loved it! Got this second one for my bedroom and love it even more with the newly added features like dimming and the added light option. Not to mention the lighting offers a great mood to any room :)
