I'm a believer! I've been running the older 90 watt K7 Pro II for about a year now. Recently I purchased a 75 watt V3 and love it! I'm in the process of setting up a new tank so I got two of the 140 watt V3. I'm loving them! Thanks Noopsyche!

Great controller, it was very easy to set. I am using the SPS/LPS settings, just did some adjustments to the timers. It was easy.

I love these lights! They make my tank look amazing. Just set them on the LPS setting and done. They have a nice smooth ramp up and beautiful shimmer. They also look great physically with their small size and nice stands. Thank you Noopsyche!!

Very impressed with the light. They're amazing.

I'd be grateful as I am just getting back in to the hobby after about 20 years and these looks fantastic. I set up a 125. ;-)

Awesome light. Although some reviews say that it was difficult to program, the programming was not bad. Overall happy so far.

I am new to the group but I would be more than thankful as I have just recently setup a new reef cube. Been out of reef tanks for about 20 years but I and getting back into the hobby.

Happy Holidays

This looks like a very nice light and all of the comments I have read on it and pictures I've seen of corals growing under the lights say this is the kind of lamp I'm looking for. Looking to upgrade from a 15 gallon peninsula style to a 40 breeder but the AI Prime I have just isn't going to cut it on that size tank.

I now have 6 of the K7 V3 140w lights over my SPS dominant reef tank. The build quality and performance of these lights is far better than the price would indicate. The only negative about these is the lack of an app to control the lights and the controller. The controller is cheap feeling, and a little confusing at first, but once you get used to the controls setting the light programming isn't too bad.
If these lights had an app to control them, or even better a 0-10v control port so they could be controlled with an aquarium controller, then they could rival the lights from the major high end manufacturers in my opinion.
If you need high quality reef lighting and don't want to spend a fortune on Radions, Kessil, SKY, etc then the K7 V3 is a good substitute at a fraction of the cost.

Nicer than a kessil mixing and shimmer.

Great light for my 40 breeder.

Would be a great upgrade for my rebuild had to start all over Dam Hurricane IDA

PAR/PUR levels are absolutely amazing. 10/10 At 40% output I get over 100 par on my sandbed. This is 32 inches from the light. I had to turn these down for my bubble tip anemone as 40% was too strong. My old lights are equal to 20% of these lamps. Much acclimation is needed.

Now for the controller. This is a built in control, display screen. There is no implemented web control for the lights. I am absolutely okay with this. I have enough on my computer as it is. It will save 2 light settings. So if you want to toggle between 2 light programs you can do so. I rate this 8/10
In order to measure par, I must keep the control active on light schedule. This is okay. I would like to leave the controller alone while recording the different light settings. The only reason for the 8/10 stars.

Cord length is very generous. I actually like the way it is designed. Should anything happen to the cord, you will now need to repair the whole unit. There are 3 sections of the cord. 1. Power cable. 2. the power box cable 3. you have the cord on the light. This is well over 10feet in length. 10/10

Next up is the looks. Very sleek. I love the overall design and look. I can't say I could ask for more improvement on ascetics. 10/10

Mounting brackets I find they are like any other bracket to use. No real positive or negatives. I did mount these on the outside of my canopy. So that is a big plus for the design. The bracket offers a very generous 1 and a fourth inch opening for framed tanks. Very strong and stable, will not work for euro bracing, I never found bracing that does. I am sure there is a work around.

Overall, I am extremely pleased with these lights. I do not think there is better for the price tag.

Sadly, I cannot find where to post pictures. Hopefully I can add those later.

Footprint and spectrum of these lights are great.
