First one I received didn't work upon arrival. Replacement worked for just 3 weeks then stopped working. Very cheaply made. There are much better options out there.

I like how quiet this ballast runs and am blown away at how bright this is. Very impressed extreme power ( I have to dial back to %75 , never had too that ) crisp instant striker, good investment, let's see if it hold up, I sure hope so, it's a beast.

The 1000wtt ballast are working exactly the way they should with no problems, will be replacing all our ballast to tophort, the light weight makes for easy mounting. And no overheating and quite running.

Does not work after 1 month stay away if you value your grow. I have to go down to my tent everyday at 7am thats when my lights go on and unplug and plug back in numerous times to get this piece of junk to go on as its does not go one with the timer. I have to think its a quality issue. Came back to add to this so its been 4 days and no contact from the manufacturer and Amazon has given me the wrong contact info for them when I asked for the right contact info they can not help me. When I google TOPHORT I only get adds I can not find them and they have no web site on any of the box it came in no warranty card nothing. DO NOT BUY get a different one.

Had high hopes for this brand after switching from a vivosun, haven't had a dimmable Electronic Ballast last any longer than a grow and a half in my life, there's something innately flawed with these things, if i were you just buy a quantum board led, for however many times you'll spend replacing these things you may as well.

The ballast worked with no problems. My vivosun ballast went out on me so I bought this as a replacement.. Don’t know how long it will last but will see.

Purchased Oct 28, 2019 and by Jan 8 2020 was dead.SEE UPDATE BELOWI have four 1000 watt MH/HPS automatic ballasts in the greenhouse. Three were purchased 1.5 years ago and there have been no problems. I could not find that model any longer, so I tried this one (TOPHORT). I've been buying 1000 watt ballasts for over 10 years, and I've never had one BREAK DOWN AFTER 3 MONTHS. I cannot recommend this to anyone.UPDATEThe seller is replacing the unit completely free of charge! It doesn't get any better than this.

I bought this ballast since my apollo finally bit the dust after 5 years. I was gonna go back to apollo since it lasted so long but noticed that they weren't available anymore on amazon. This ballast shipped fast and took seconds to hook up. It comes with a 2 year warranty so hopefully it atleast last that long. I was a little worried that the ballast plug in wouldn't work with my apollo hood but everything hooked up just fine

I am returning this because the electrical connection is not compatible with my light bulb. Came to find out that I needed to order a reflected which has a plug n play connection with the ballast’s. I was not aware of that at purchase.September 2019I ended up not returning this and making it work Big thanks to the supplier of this ballast that showed great customer service and technical support. The supplier was very generous to send me the adapter that makes it possible to connect to my bulb.
