Review: Dont think twice! Save some money without losing quality! BUY THIS LIGHT!! - I'm going to save you money and time... Are you ready? BUY THIS LIGHT!! this thing is so awesome!! I have a rather small enclosure for flowering so they stay pretty close to the plants. Ive been running this light for about a week now and its a huge upgrade from 2 100w quantum boards. No doubt this light can flower out a whole 4x4 tent. The light does an awesome job at dispersing heat. In my tiny enclosure i barely notice a change in temps. I had a bit of a fiasco recieving my light but maxsisun has awesome customer service! They helped me out the whole way through the process. I never lost contact with them and they made sure I was satisfied with my purchase. Before spending so much money on a light i wanted to make sure i did my research on it. I contacted them before i bought the light to ask about specifics and they were more then happy to help... Not so much with other light companies. Great customer service goes a long way in my book and i look forward to working with them again. The light is awesome. The customer service is outstanding! The price is more then great! What are you waiting on? Scroll back up and click add to cart!! Thank you maxsisun!!
Review: Put A Couple Mother’s Thru Hell & Bacc - 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 🥶

### ⭐⭐⭐⭐⭐ Better then most !
*by E***. on April 26, 2022*

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
