## Customer Reviews

### ⭐⭐⭐⭐⭐ Very impressive performance!
*by M***T on October 18, 2020*

As a business that specializes in building custom automated hydroponic systems we have tested several dozen lighting solutions for indoor applications. Our lighting testing procedure compares tried and true lighting solutions like fluorescent and HID lights to a given LED fixture. The results (in short) of the Maxsisun PB 4000 tested against a HO 6 bulb T5 fixture and a 600 watt HID (MH/HPS) fixture was staggering. The PB 4000 far out performed the T5 fixture and due to the much lower power consumption rate the PB 4000 it crushed the HID light even though the efficacy was about the same. Even though most of the quantum board LED fixtures are yielding very impressive results they seem to have very comparable efficacy, the major advantages of the Maxsisun fixtures however is price per watt and performance comparable to fixtures 4 times the cost. Are there better LED fixtures? That’s still up for debate. Some of the more expensive fixtures have not responded to our request to include them in our testing cycle which give me some doubt about their claims and cost vs. efficacy. For the price and the performance of the PB 4000 why would you need a $1,600 light when a $400 one does the trick?ALL effective lighting makes heat, It’s that simple, this fixture is no different. Growers need to have a means in which to remove the heat generated by the fixture, JUST LIKE ANY OTHER EFFECTIVE FIXTURE! If you’ve ever used HID lighting fixtures you know that these lights generate as much energy in heat as they do light. Heat metagation is a full time job for the indoor grower. As long as you’ve got a plan for dealing with the heat there is no problem. However it’s a thermodynamic issue so your solution should include a little math so your grow space isn’t positive or negative pressure. Having said that, we are very pleased with our experience and will be using the Maxsisun line of lighting fixtures in our FlexFarm equipment.

### ⭐⭐⭐⭐⭐ Put A Couple Mother’s Thru Hell & Bacc
*by K***I on August 2, 2021*

The media could not be loaded. Well I’ve shown more then just a demonstration, ran a test, grew one of my autoflower strains, and put it to the test on this light because I expected nothing but quality for the cost of this light. Yes it gives off heat, but if you’re smart and work smarter and not harder you can use it efficiently and it puts out great LED lighting for females. This an autoflower, 90 day cycle finished before 90 days of course…. Tortured the whore, made her my bitch and she flowered and I made sure she showed her true colors at the end of the day. Don’t mind me, don’t get at me either. Nobody really spends the time to review a product anyways, everyone complains about electronics coming from another country and built to last but actually break. This isn’t the story with this here device. I didn’t even use it on 100% LED lighting it has a dimmer. I ran it 40% and 10% most of the 3 month period. I’ve grown MULTIPLE AUTOS AS WELL. This one particular no training No LST, no trellis, no HST, just organic nutrients from the soil, roots organic mix, great amount of perlite the right temps at all times 75-80 barely drops below 71 in cold temps if anything…. Running experiments like Mad Max ! Keepin it legit runnin cool. Fans blowing on it I’m using the PB4000 jus so you know I ain’t grabbin ya balls and twisting your theories. It’s not the best light but I see it does better then most… especially to good genetics, any other genetics prolly would’ve killed the poor lady due to bad genes, and light intensity which happened to this her female, that actually fattened like a cake, the smoke is minty, sweet and spicy on this phenotype in this grow tent, 4x4 more then enough space maybe I should’ve dropped the cash for spider farms but I would’ve had to make other adjustments and nobody just has money laying around unless your bill gates! Anyways, worth the money, def, I used only water keep it natural conservative, and ready for another job. Also keep in mind autoflowers will continue to make & develope more pistils and trichomes, I wanted to go full amber % on that one particular auto. I’ve made my point and it sounds ignorant but hopefully this was helpful information…. Cheap light build quality ehhh does its job not mad, it was either this or spyder and honestly happy with my purchase because I prefer LED over HPS sorry not sorry. Heat efficient 🥶

### ⭐⭐⭐⭐⭐ The only review you need to read!
*by J***A on February 9, 2021*

I bought one of these early in the summer of 2020. I used it to grow tomato and pepper plants and it was amazing. I used it for some other plants and it seemed to stumble. I used Korona light meter phone app and realized that it was too close and the plants were experiencing light stress. Using the meter and ppfd guidelines I had to back the light off a full 10” to get the advertised light output.My plants recovered and grew extremely well. I’m not used to these budget lights under representing their output but it was refreshing. This light is a solid performer!.I’m using it to cover half of a 4x8 tent. I’ve had suck good luck with it I ordered a second Sunday. It arrived today in excellent condition. These are shipped directly from Maxxisun with thick, hard shipping boxes and foam inserts. It is very well protected in transit. I now have full coverage in my 4x8.I came here to leave a review of my experiences with this light and seen it was 100 off from my purchase Sunday and bought a third.I’m super fussy. I expect products to arrive immaculate and perform flawlessly. The fact that I’ve purchased three of these lights and I am completely happy speaks for itself.Prior to this I had used the Mars Hydro TS full spectrum lights. I liked them. They had a few extra features like daisy chain, and dimmer switches, but this light is so much brighter and just don’t stop performing. I have plans to add a dimmer control myself later. It can be done and google will help.
