    • It lasted one day before a Meanwell blew
I love the light so I bought a new Meanwell XLG-240-H-AB driver. It was about $50 and easy to replace because I just cut the wires and reconnected them to the new driver.

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 🥶 ... show more

    • Very impressive performance!
Review Image by Mailinqueput
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. ... show more

    • Better then most !
Review Image by Eddy M.
Had several lights and tried one of these and was hooked. Tried the spider farmer sf4000 wasnt impressed , tried the sonofarm 4000 was definitely lacking brightness. What i can tell you is this light was worth it. Now i own a total of 5 and will purchase more if they become availible. Soon as i put my girls under her for flower they grow about an additional foot . They stay a nice green healthy color. Buds explode and grow tight with these lights. The build quality is top notch. The aluminum base is way thicker then any other light by about 3 to 4 times. Kts about id say a quarter inch to a half thick . Ill measeure later. The meanwell driver actually is raised of the aluminum over a half inch so it can actually breathe. The cord that attach it are metal and coated with a plastic. Trust me you will love thos light. Enjoy ... show more
