Review: Fantastic outdoor grow light - Love how my shady tree trunk area is no longer a problem area for my succulents. I have purchased eight of these over the last four years and yes, they only last three to four years but give me success where before I had failure. I did get a single new one shipped to me for free after I contacted customer service about numerous of them failing after three and some after four years. I'd say at this price point that it is worth it. I do have to play with the distance that is necessary for them to grow, the lights are not strong enough to place too far away.

### ⭐⭐⭐⭐⭐ Plug is not waterproof
*by L***G on June 17, 2026*

It’s working great!

### ⭐ Not recommended and search for another one
*by J***I on May 27, 2026*

These lights have good spectrum and definetely helps plants grow. However being 450W surely raises the electricity bill. Also when hanged the lamp handle starts to weaken and then the position that you need for them can't be hold. Lastly the durability is around a year or so. I bought three and the first two that I put into work already stopped working. I would suggest anyone searching for growlights to invest in another lamp than this.
