No problems. Well worth the purchase.

Bought this lil light to try to grow herbs and tomatoes because the bugs are very bad where we live and I don't like using pesticides . I haven't got to start any plants yet but wow that light is very bright so I'm sure it will do the job I need it to do . The build quality is very nice and made in the USA so that was a major selling point and the shipping was very fast.

I have purchased 3 of these lights.
1 new and 2 refurbished.
I have 2 lights with a whiter or more blue visible light.
I also have 1 that give a more visibly red light.
Not sure if it makes a difference but my plants seem to grow 9knfor now.

I’ve been using t-5 high bay lights to start my plants indoors, but my selves are spaced for 18” height from the bulbs to the 10” x 20” flats; so I needed lights to grow on after the plants grow a bit. These lights seem to be working ok, actually I had mature lettuce in five weeks. Future successions will go out side, but it’s nice to be eating lettuce in mid March.

I have set up two solarsystem550 with controller in a small indoor room to grow veggies/etc year round. I am pleased with the lights and controller. Easy to adjust R,W,B and time. I have only had the lights running for two days, but can see they are exactly what I wanted. Thank you!!

Very pleased with this lights performance and would definitely recommend. I may buy another in the near future.

Replaced an old high intensity light. Solar Extreme 600 is smaller, lighter and cooler. Arrived promptly, well packaged has worked just fine. I Recommend it.

So I have not used it for its reasoning yet but I have set it up and turned it on, it’s a very intense light, reaches very far. I have it set between 2 1500 lights.

I only bought recently, but it is a quality product. My plants are just entering flowering so can not comment on whether this improves terpenes or trichomes. I will know in a month after using for 2 hrs daily.

The light is no-frills, meaning no adjustment to levels and no on/off switch. Also no ratchet hangers included. I personally have not found that the light level adjustment on other brands is much good to me, as I always have it on the highest setting, but if that feature is important to you this is not the unit. It is very solid and compact with fans on top rather than heat sinks on the drivers like some brands have. The form factor is really nice.

This comment is aside from the product itself, but customer service is total joke. There is a chat feature but no one monitors it. There is an email option but no one responds. I have unanswered questions about my account, and as a result have not purchased a second light as I was going to.

Just went 12/12. Will find out

Shipped on time, lights and controller works as advertised.

Great light, plants happy. This runs very hot though - plan accordingly with circulation and cooler inflow air

The light was delivered promptly and set up. Everything is awesome and much appreciated. Second one in the next weeks actually. Danke!
