Worked as described.
By Rob on Reviewed in the United States on January 1, 2013
I bought this item based on the reviews here to grow leafy vegetables indoors during the winter. I have no previous experience with indoor growing or HID lights at all. The item arrived precariously packaged though. I had bought some soil at the same time and these items were bundled together in the same box from Amazon. When I opened the box the huge bag of soil was on top of the box with the lights! There was a little crushing, and I expected the bulbs to be shattered but thankfully everything was in working order. I knew from searching around online that they put out a lot of heat, and this item is no exception to that rule. The el-cheapo amazon tent I bought had its temperatures raised around 10f after I fired this badboy up. The heat was easily mitigated with a inline fan and some simple ducting. The only real problem I encountered when moving air out of the tent was the incredibly bad smell of my cherry tomato plants. Guys who grow medicinal herbs recommend using a carbon filter, so I guess I will begin research on that soon! Here are a few things I thought were relevant: -The ballast is quite small and makes a light humming sound from cooling fans. It stays cool to the touch. Dimming the bulb is achieved via a silver knob that shows the power percent level. The ability to dim the bulbs is rather handy in controlling temperatures. -The wing reflector feels incredibly flimsy. The socket assembly to screw the bulb into feels just as flimsy. -The eyes to hang the reflector by are actually just metal tabs that need to be folded up in order to use. This is just sheet metal that could easily break if flexed too many times. I would suggest just bending them out once and leaving them alone. -The power cables are quite long and seem to be made very well. -The bulbs seem generally good. I have very little experience in this area, but they light up and are blindingly bright. -The included rope ratchets are just the generic type of ratchet found here on Amazon. I have ordered 2 different brands and received the exact same item both times. Works like a champ. I think for the price this is a very good deal. It's just not logical to complain about a item feeling cheap when it was the cheapest thing available! I believe generally you get what you pay for, but in this items regard I believe you get more than that. It becomes a incredible deal with prime shipping added in. If I decide that 400 watts isn't enough I would not hesitate to buy another iPower bundle.

HORRIBLE RF Interference; this ballast will bring unwanted attention.
By Yelsew Nafets on Reviewed in the United States on February 3, 2013
Before you purchase, do a web search "iPower RF Interference" and you'll get most of your info there. I had a bizarre personal experience, and I can tell you that unless you're into the idea of a white van with tinted windows pulling up to your house, and/or guys with a Db meter hanging outside your door, this ballast is NOT for you. It will cause your network equipment and possibly others around yours to malfunction if placed too close to a cable line. Cheaply made in China, no FCC stickers, it is actually probably illegal for Amazon to sell this. As far as the light , it works great. HPS and MH bulbs are top notch and superb color spectrum. Couldn't ask for anything else in terms of performance but as I mentioned, having your Internet bomb out on a Saturday night with an unwarranted visit is the last thing you want if you're a simple quiet person trying to hang below the radar. It did make me take a closer look. I am a professional recording engineer (and review writer apparently) so using music studio mics I did an AM radio test and was shocked to find that from just 8ft away from my building there is a +6Db increase of RF noise while the ballast is powered on. A 3Db increase is DOUBLE what the human ear can hear (meaning a change in power ratio by a factor of two is approximately a 3 dB change). So as you can tell having that multiplied by two is not good at all. This is important because the guys "probing" my apartment area used a handy tool called an "Ultraprobe 2000", which can pick up even just a 1db increase from 800+ feet away. It can also give an infrared reading of the heat signature the light gives off. Space age stuff really, big brother stuff even. This RF interferrence is subject affecting various comms equipment, including smartphones, wireless routers, modems, etc. When the ballast is dialed to just 200w, you will literally see your wifi suffer if it is too close to a cable line as mine was. At 300w the wifi completely shut down, as well as my neighbors, which shortly after led to a knock on my door. I am beyond the 30 day return period but I did present a case to Amazon that they are possibly selling non-FCC regulated products on their site and they gladly honored my return. :)
