Review: Water proof - This is the best outside light you can buy for your garden, the plants love it!
Review: 5 hot, rainy summers later, still going strong... - Ok, I thought I reviewed this a couple of years ago, but I can't find it. I bought two of these lights in 2020 for my outdoor garden because my tomatoes weren't getting enough sunlight during the day. I live in a very hot, humid environment on the East Coast. I have used these lights almost every summer for the past FIVE YEARS. I hang them over my garden, put them on a timer and they work like a charm. By this point they are a tiny rusted, but they STILL WORK. These babies have been left outside for at least four hot, very rainy summers. I have done nothing to upkeep them. I am probably cursing myself in writing this, but I find it somewhat rare to find quality items these days. Love them. Photo taken below is from last night.

### ⭐ 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.
